 <div class="block">The <code>Query</code> interface allows applications to obtain persistent
  instances, values, and aggregate data from the data store.

  The <a href="../../javax/jdo/PersistenceManager.html" title="interface in javax.jdo"><code>PersistenceManager</code></a> is the factory for <code>Query</code>
  instances.  There may be many <code>Query</code> instances associated with a
  <code>PersistenceManager</code>.  Multiple queries might be executed
  simultaneously by different threads, but the implementation might choose to
  execute them serially.  In either case, the implementation must be thread-safe.

  <P>There are three required elements in a <code>Query</code>: the class of
  the results, the candidate collection of instances, and the filter.

  <P>There are optional elements: parameter declarations, variable
  declarations, import statements, ordering and grouping specifications,
  result and result class, the range of results,
  and flags indicating whether the query result
  is unique and whether the query can be modified.
  <P>The query namespace is modeled after methods in Java:
  <ul>
  <li><code>setClass</code> corresponds to the class definition
  <li><code>declareParameters</code> corresponds to formal parameters of a method
  <li><code>declareVariables</code> corresponds to local variables of a method
  <li><code>setFilter</code> and <code>setOrdering</code> correspond to the method body
  </ul>
  <P>There are two namespaces in queries. Type names have their own namespace
  that is separate from the namespace for fields, variables and parameters.
  <P>The method <code>setClass</code> introduces the name of the candidate
  class in the type namespace. The method <code>declareImports</code>
  introduces the names of the imported class or interface types in the type
  namespace. Imported type names must be unique. When used (e.g. in a parameter
  declaration, cast expression, etc.) a type name must be the name of the
  candidate class, the name of a class or interface imported by method
  <code>declareImports</code>, or denote a class or interface from the same
  package as the candidate class.
  <P>The method <code>setClass</code> introduces the names of the candidate
  class fields.
  <P>The method <code>declareParameters</code> introduces the names of the
  parameters. A name introduced by <code>declareParameters</code> hides the
  name of a candidate class field of the same name. Parameter names must be
  unique.
  <P>The method <code>declareVariables</code> introduces the names of the
  variables.  A name introduced by <code>declareVariables</code> hides the name
  of a candidate class field if equal. Variable names must be unique and must
  not conflict with parameter names.
  <P>The result of the query by default is a list of result class instances,
  but might be specified via <code>setResult</code>. The class of the result
  by default is the candidate class, but might be specified via <code>setResultClass</code>.
  <P>A hidden field may be accessed using the 'this' qualifier: <code>this.fieldName</code>.
  <P>The <code>Query</code> interface provides methods which execute the query
  based on the parameters given. They return a single instance or a
  <code>List</code> of result class instances which the
  user can iterate to get results. The signature
  of the <code>execute</code> methods specifies that they return an
  <code>Object</code> which must be cast to the appropriate result by the user.
  <P>Any parameters passed to the <code>execute</code> methods are used only
  for this execution, and are not remembered for future execution.</div>

 <div class="block">Set the filter for the query.
  <P>The filter specification is a <code>String</code> containing a Boolean
  expression that is to be evaluated for each of the instances
  in the candidate collection. If the filter is not specified,
  then it defaults to "true", which has the effect of filtering
  the input <code>Collection</code> only for class type.
  <P>An element of the candidate collection is returned in the result if:
  <ul><li>it is assignment compatible to the candidate <code>Class</code>
  of the <code>Query</code>; and
  <li>for all variables there exists a value for which the filter
  expression evaluates to <code>true</code>.
  </ul>
  <P>The user may denote uniqueness in the filter expression by
  explicitly declaring an expression (for example, <code>e1 != e2</code>).
  <P>Rules for constructing valid expressions follow the Java
  language, except for these differences:
  <ul>
  <li>Equality and ordering comparisons between primitives and instances
  of wrapper classes are valid.
  <li>Equality and ordering comparisons of <code>Date</code> fields and
  <code>Date</code> parameters are valid.
  <li>White space (non-printing characters space, tab, carriage
  return, and line feed) is a separator and is otherwise ignored.
  <li>The assignment operators <code>=</code>, <code>+=</code>, etc. and
  pre- and post-increment and -decrement are not supported. Therefore,
  there are no side effects from evaluation of any expressions.
  <li>Methods, including object construction, are not supported, except
  for <code>Collection.contains(Object o)</code>,
  <code>Collection.isEmpty()</code>,
  <code>String.startsWith(String s)</code>, and
  <code>String.endsWith(String e)</code>.  Implementations might choose to
  support non-mutating method calls as non-standard extensions.
  <li>Navigation through a <code>null</code>-valued field, which would
  throw <code>NullPointerException</code>, is treated as if the filter
  expression returned <code>false</code> for the evaluation of the current
  set of variable values. Other values for variables might still qualify
  the candidate instance for inclusion in the result set.
  <li>Navigation through multi-valued fields (<code>Collection</code>
  types) is specified using a variable declaration and the
  <code>Collection.contains(Object o)</code> method.
  </ul>
  <P>Identifiers in the expression are considered to be in the name
  space of the specified class, with the addition of declared imports,
  parameters and variables. As in the Java language, <code>this</code> is a
  reserved word which means the element of the collection being evaluated.
  <P>Navigation through single-valued fields is specified by the Java
  language syntax of <code>field_name.field_name....field_name</code>.
  <P>A JDO implementation is allowed to reorder the filter expression
  for optimization purposes.</div>

  to the candidate class of the query. If the result consists of one
  expression, the result class defaults to the type of that expression.
  If the result consists of more than one expression, the result class
  defaults to Object[].
  The result class may be specified to be one of the java.lang classes
  Character, Boolean, Byte, Short, Integer, Long, Float, Double, String,
  or Object[]; or one of the java.math classes BigInteger or BigDecimal;
  or the java.util class Date; or one of the java.sql classes Date,
  Time, or Timestamp; or a user-defined class.
  <P>If there are multiple result expressions, the result class
  must be able to hold all elements of the result specification
  or a JDOUserException is thrown.
 <P>If there is only one result expression, the result class must be
  assignable from the type of the result expression or must be able
  to hold all elements of the result specification. A single value
  must be able to be coerced into the specified result class
  (treating wrapper classes as equivalent to their unwrapped
  primitive types) or by matching. If the result class does not satisfy
  these conditions, a JDOUserException is thrown.
 <P>A constructor of a result class specified in the setResult method
  will be used if the results specification matches the parameters
  of the constructor by position and type. If more than one constructor
  satisfies the requirements, the JDO implementation chooses one of them.
  If no constructor satisfies the results requirements, or if the result
  class is specified via the setResultClass method, the following
  requirements apply:
  <ul>
  <li>A user-defined result class must have a no-args constructor and
  one or more public <code>set</code> or <code>put</code> methods or
  fields.
  <li>Each result expression must match one of:
  <ul>
  <li>a public field that matches the name of the result expression
  and is of the type (treating wrapper types equivalent to primitive
  types) of the result expression;
  <li>or if no public field matches the name and type, a public
  <code>set</code> method that returns void and matches the name of the
  result expression and takes a single parameter which is the
  exact type of the result expression;
  <li>or if neither of the above applies,a public method must be found
  with the signature <code>void put(Object, Object)</code>.
  During processing of the results,
  the first argument is the name of the result expression and
  the second argument is the value from the query result.

 <div class="block">Add a subquery to this query.
  A subquery is composed as a Query and subsequently attached
  to a different query (the outer query) by calling this method.
  The query parameter instance is unmodified as a result of the
  addSubquery or subsequent execution of the outer query.
  Only some of the query parts are copied for use as the subquery.
  The parts copied include the candidate class, filter, parameter
  declarations, variable declarations, imports, ordering specification,
  uniqueness, result specification, and grouping specification.
  The association with a PersistenceManager, the candidate collection
  or extent, result class, and range limits are not used.
  The String parameters are trimmed of white space.
  The variableDeclaration parameter is the name of the variable
  containing the results of the subquery execution. If the same value
  of variableDeclaration is used to add multiple subqueries, the
  subquery replaces the previous subquery for the same named variable.
  If the subquery parameter is null, the variable is unset,
  effectively making the variable named in the variableDeclaration
  unbound. If the trimmed value is the empty String, or the parameter
  is null, then JDOUserException is thrown.
  The candidateCollectionExpression is the expression from the
  outer query that represents the candidates over which the subquery
  is evaluated. If the trimmed value is the empty String, or the
  parameter is null, then the candidate collection is the extent
  of the candidate class.
  The String... version of the method binds the named expressions in
  turn to parameters in the order in which they are declared in the
  subquery, or in the order they are found in the filter if not
  explicitly declared in the subquery.</div>
