A predicate DSL for matching javac AST nodes.

See: Description

Interface Summary

Interface	Description
Matcher<T extends com.sun.source.tree.Tree>	Define a predicate on a Tree, which also accesses the state of AST traversal.
MultiMatcher<T extends com.sun.source.tree.Tree,N extends com.sun.source.tree.Tree>	An matcher that applies a single matcher across multiple tree nodes.
Suppressible

Class Summary

Class	Description
AbstractTypeMatcher<T extends com.sun.source.tree.Tree>	Base class for type matchers.
AnnotationDoesNotHaveArgument	Matches an annotation that does not have a particular argument, possibly because the default value is being used.
AnnotationHasArgumentWithValue
AnnotationMatcher<T extends com.sun.source.tree.Tree>	Matches if the given annotation matcher matches all of or any of the annotations on the tree node.
AnnotationMatcherUtils	Utilities for matching annotations.
AnnotationType
Asserts	Matches assert statements which have a condition expression matched by the given matcher.
ChildMultiMatcher<T extends com.sun.source.tree.Tree,N extends com.sun.source.tree.Tree>	A MultiMatcher that applies a matcher across multiple children of a single ancestor node.
CompileTimeConstantExpressionMatcher	A matcher for compile-time-constant expressions.
CompoundAssignment	Matcher for a compound-assignment operator expression.
ConstructorOfClass	Applies the given matcher to the constructor(s) of the given class.
Contains	A matcher that recursively inspects a tree, applying the given matcher to all levels of each tree and returning true if any match is found.
Description	Simple data object containing the information captured about an AST match.
Description.Builder	Builder for Descriptions.
Enclosing	Adapt matchers to match against a parent node of a given type.
Enclosing.Block<T extends com.sun.source.tree.Tree>
Enclosing.BlockOrCase<T extends com.sun.source.tree.Tree>
Enclosing.Class<T extends com.sun.source.tree.Tree>
Enclosing.Method<T extends com.sun.source.tree.Tree>
FieldMatchers	Static utility methods for creating Matchers for detecting references to fields.
HasArguments	Matches if the given matcher matches all of/any of the parameters to this method.
HasIdentifier	Matches if the given matcher matches all of the identifiers under this syntax tree.
InjectMatchers	Utility constants and matchers related to dependency injection.
IsSameType<T extends com.sun.source.tree.Tree>	Matches an AST node if its erased type is the same as the given type, e.g.
IsSubtypeOf<T extends com.sun.source.tree.Tree>
JUnitMatchers	Matchers for code patterns which appear to be JUnit-based tests.
Matchers	Static factory methods which make the DSL read more fluently.
MethodHasParameters	Matches if the given matcher matches all of/any of the parameters to this method.
MethodInvocation	Matches a method invocation based on a matcher for the method select (receiver + method identifier) and one for the arguments.
MethodInvocationArgument	Applies an Expression matcher to an argument of a MethodInvocation by position.
MethodInvocationMethodSelect	Adapts a matcher on MethodInvocationTree to match the MethodSelect of the MethodInvocation.
MethodVisibility	A matcher for method visibility (public, private, protected, or default).
MultiMatcher.MultiMatchResult<N extends com.sun.source.tree.Tree>	A result from the call of MultiMatcher.multiMatchResult(Tree, VisitorState), containing information about whether it matched, and if so, what nodes matched.
NullnessMatcher	Matches an expression based on the result of the nullness dataflow analysis.
Returns	Matches a return statement whose returned expression is matched by the given matcher.
StringLiteral
Throws	Matches a throw statement whose thrown expression is matched by the given matcher.
WaitMatchers	Matchers for method invocations related to Object.wait() and Condition.await();

Package com.google.errorprone.matchers Description

A predicate DSL for matching javac AST nodes. This allows concise, readable declarative code for describing a match, by composing generic-type-safe matchers on the inspected AST subtree.
