Method Summary

Modifier and Type	Method	Description
protected Description	describeReturnValueIgnored(com.sun.source.tree.MethodInvocationTree methodInvocationTree, VisitorState state)	Fixes the error by assigning the result of the call to the receiver reference, or deleting the method call.
com.google.common.collect.ImmutableMap<String,?>	getMatchMetadata(com.sun.source.tree.ExpressionTree tree, VisitorState state)	Returns a map of optional metadata about why this check matched the given expression.
protected Matcher<? super com.sun.source.tree.ExpressionTree>	specializedMatcher()	Match whatever additional conditions concrete subclasses want to match (a list of known side-effect-free methods, has a @CheckReturnValue annotation, etc.).

Method Details

specializedMatcher

protected Matcher<? super com.sun.source.tree.ExpressionTree> specializedMatcher()

Description copied from class: AbstractReturnValueIgnored

Match whatever additional conditions concrete subclasses want to match (a list of known side-effect-free methods, has a @CheckReturnValue annotation, etc.).

Specified by:

specializedMatcher in class AbstractReturnValueIgnored

getMatchMetadata

public com.google.common.collect.ImmutableMap<String,?> getMatchMetadata(com.sun.source.tree.ExpressionTree tree,
 VisitorState state)

Description copied from interface: ResultUsePolicyAnalyzer

Returns a map of optional metadata about why this check matched the given expression.

describeReturnValueIgnored

protected Description describeReturnValueIgnored(com.sun.source.tree.MethodInvocationTree methodInvocationTree,
 VisitorState state)

Description copied from class: AbstractReturnValueIgnored

Fixes the error by assigning the result of the call to the receiver reference, or deleting the method call. Subclasses may override if they prefer a different description.

Overrides:
