| <p> The package <tt>org.apache.lucene.queryparser.flexible.config</tt> contains query configuration handler abstract class that all config handlers should extend. </p> |

| <p> The <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.QueryConfigHandler.html">QueryConfigHandler</a> and <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.FieldConfig.html">FieldConfig</a> are used in the processors to access config information in a flexible and independent way.

| <h4><a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.AbstractQueryConfig.html">AbstractQueryConfig</a></h4> |
| <section><p>This class is the base of <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.QueryConfigHandler.html">QueryConfigHandler</a> and <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.FieldConfig.html">FieldConfig</a>. |
| It has operations to set, unset and get configuration values. |
| <p> |
| Each configuration is is a key->value pair. The key should be an unique |
| <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.ConfigurationKey-1.html">ConfigurationKey<T></a> instance and it also holds the value's type. |

| <section><p>LUCENENET specific class used to access the NewInstance |
| static method without referring to the ConfigurationKey{T}'s |
| generic closing type.</p> |
| </section> |
| <h4><a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.ConfigurationKey-1.html">ConfigurationKey<T></a></h4> |
| <section><p>An instance of this class represents a key that is used to retrieve a value |
| from <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.AbstractQueryConfig.html">AbstractQueryConfig</a>. It also holds the value's type, which is |
| defined in the generic argument.</p> |
| </section> |
| <h4><a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.FieldConfig.html">FieldConfig</a></h4> |
| <section><p>This class represents a field configuration.</p> |
| </section> |
| <h4><a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.QueryConfigHandler.html">QueryConfigHandler</a></h4> |
| <section><p>This class can be used to hold any query configuration and no field |
| configuration. For field configuration, it creates an empty |
| <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.FieldConfig.html">FieldConfig</a> object and delegate it to field config listeners, |
| these are responsible for setting up all the field configuration. |
| <p> |
| <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.QueryConfigHandler.html">QueryConfigHandler</a> should be extended by classes that intends to |
| provide configuration to <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Processors.IQueryNodeProcessor.html">IQueryNodeProcessor</a> objects. |
| </p> |
| <p> |
| The class that extends <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.QueryConfigHandler.html">QueryConfigHandler</a> should also provide |
| <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.FieldConfig.html">FieldConfig</a> objects for each collection field. |

| <section><p>This interface should be implemented by classes that wants to listen for |
| field configuration requests. The implementation receives a |
| <a class="xref" href="Lucene.Net.QueryParsers.Flexible.Core.Config.FieldConfig.html">FieldConfig</a> object and may add/change its configuration.</p> |
