| <pre>public final class <span class="typeNameLabel">Preconditions</span> |
| extends <a href="https://docs.oracle.com/javase/8/docs/api/java/lang/Object.html?is-external=true" title="class or interface in java.lang">Object</a></pre> |
| <div class="block">Static convenience methods that help a method or constructor check whether it was invoked |
| correctly (whether its <i>preconditions</i> have been met). These methods generally accept a |
| <code>boolean</code> expression which is expected to be <code>true</code> (or in the case of <code>checkNotNull</code>, an object reference which is expected to be non-null). When <code>false</code> (or |
| <code>null</code>) is passed instead, the <code>Preconditions</code> method throws an unchecked exception, |
| which helps the calling method communicate to <i>its</i> caller that <i>that</i> caller has made |
| a mistake. Example: <pre> <code> |
| |
| /** |
| * Returns the positive square root of the given value. |
| * |
| * @throws IllegalArgumentException if the value is negative |
| *</code><code> / |
| public static double sqrt(double value) { |
| Preconditions.checkArgument(value >= 0.0, "negative value: %s", value); |
| // calculate the square root |
| } |
| |
| void exampleBadCaller() { |
| double d = sqrt(-1.0); |
| }</code></pre> |
| |
| <p>In this example, <code>checkArgument</code> throws an <code>IllegalArgumentException</code> to indicate |
| that <code>exampleBadCaller</code> made an error in <i>its</i> call to <code>sqrt</code>. |
| |
| <h3>Warning about performance</h3> |
| |
| <p>The goal of this class is to improve readability of code, but in some circumstances this may |
| come at a significant performance cost. Remember that parameter values for message construction |
| must all be computed eagerly, and autoboxing and varargs array creation may happen as well, even |
| when the precondition check then succeeds (as it should almost always do in production). In some |
| circumstances these wasted CPU cycles and allocations can add up to a real problem. |
| Performance-sensitive precondition checks can always be converted to the customary form: |
| <pre> <code> |
| |
| if (value < 0.0) { |
| throw new IllegalArgumentException("negative value: " + value); |
| }</code></pre> |
| |
| <h3>Other types of preconditions</h3> |
| |
| <p>Not every type of precondition failure is supported by these methods. Continue to throw |
| standard JDK exceptions such as <a href="https://docs.oracle.com/javase/8/docs/api/java/util/NoSuchElementException.html?is-external=true" title="class or interface in java.util"><code>NoSuchElementException</code></a> or |
| <a href="https://docs.oracle.com/javase/8/docs/api/java/lang/UnsupportedOperationException.html?is-external=true" title="class or interface in java.lang"><code>UnsupportedOperationException</code></a> in the situations they are intended for. |
| |
| <h3>Non-preconditions</h3> |
| |
| <p>It is of course possible to use the methods of this class to check for invalid conditions |
| which are <i>not the caller's fault</i>. Doing so is <b>not recommended</b> because it is |
| misleading to future readers of the code and of stack traces. See |
| <a href="https://github.com/google/guava/wiki/ConditionalFailuresExplained">Conditional failures |
| explained</a> in the Guava User Guide for more advice. |
| |
| <h3><code>java.util.Objects.requireNonNull()</code></h3> |
| |
| <p>Projects which use <code>com.google.common</code> should generally avoid the use of |
| <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Objects.html?is-external=true#requireNonNull-T-" title="class or interface in java.util"><code>Objects.requireNonNull(Object)</code></a>. Instead, use whichever of |
| <a href="../../../../org/apache/arrow/util/Preconditions.html#checkNotNull-T-"><code>checkNotNull(Object)</code></a> or <code>Verify#verifyNotNull(Object)</code> is appropriate to the |
| situation. (The same goes for the message-accepting overloads.) |
| |
| <h3>Only <code>%s</code> is supported</h3> |
| |
| <p>In <code>Preconditions</code> error message template strings, only the <code>"%s"</code> specifier is |
| supported, not the full range of <a href="https://docs.oracle.com/javase/8/docs/api/java/util/Formatter.html?is-external=true" title="class or interface in java.util"><code>Formatter</code></a> specifiers. |
