com.google.errorprone.matchers.method.MethodInvocationMatcher

public class MethodInvocationMatcher
extends Object

The machinery and type definitions necessary to model and compile a single efficient matcher out of a list of MethodMatchers.MethodMatchers.

Modifier and Type	Class and Description
static class	MethodInvocationMatcher.MethodKind The kinds of things that count as a method invocation.

Method Summary

Modifier and Type	Method and Description
static Matcher<com.sun.source.tree.ExpressionTree>	compile(Iterable<MethodInvocationMatcher.Rule> rules) Constructs a Matcher that matches for method invocations (including constructor invocations) satisfying at least one of the given Rule specifications.
static <T extends com.sun.source.tree.Tree> Matcher<T>	compiledAnyOf(Iterable<Matcher<? super T>> inputs) Compose several matchers together, such that the composite matches an AST node if any of the given matchers do.

Method Detail

compiledAnyOf

public static <T extends com.sun.source.tree.Tree> Matcher<T> compiledAnyOf(Iterable<Matcher<? super T>> inputs)

Compose several matchers together, such that the composite matches an AST node if any of the given matchers do.

This is semantically equivalent to Matchers.anyOf(Iterable), but if the list of matchers contains more than one MethodMatchers.MethodMatcher, then anyMethod will do some work up front to try and optimize out the repeated work that those matchers would otherwise do. Consider profiling your matcher before using this method: the up-front work can be substantial, and if the list of matchers is small or the result of this method is not used often, the extra work may not pay for itself.

compile

public static Matcher<com.sun.source.tree.ExpressionTree> compile(Iterable<MethodInvocationMatcher.Rule> rules)

Constructs a Matcher that matches for method invocations (including constructor invocations) satisfying at least one of the given Rule specifications. For an easy way to create such Rules, see the factories in Matchers returning subtypes of MethodMatchers.MethodMatcher.
