Method Details

fixesByReplacingExpressionWithLocallyDeclaredField

public static com.google.common.collect.ImmutableList<Fix> fixesByReplacingExpressionWithLocallyDeclaredField(com.sun.source.tree.ExpressionTree input,
 Predicate<com.sun.tools.javac.tree.JCTree.JCVariableDecl> validFieldPredicate,
 VisitorState state)

Suggest replacing input with a qualified reference to a locally declared field with a similar or the same name as the input expression.

Parameters:

input - a MEMBER_SELECT or IDENTIFIER expression which should be replaced.

validFieldPredicate - Predicate used to decide which locally declared fields are appropriate candidates for replacement (e.g.: is the appropriate type)

fixesByReplacingExpressionWithMethodParameter

public static com.google.common.collect.ImmutableList<Fix> fixesByReplacingExpressionWithMethodParameter(com.sun.source.tree.ExpressionTree input,
 Predicate<com.sun.tools.javac.tree.JCTree.JCVariableDecl> validParameterPredicate,
 VisitorState state)

Suggest replacing input with a reference to a method parameter in the nearest enclosing method declaration with a similar or the same name as the input expression.

Parameters:

input - a MEMBER_SELECT or IDENTIFIER expression which should be replaced.

validParameterPredicate - Predicate used to decide which method parameters are appropriate candidates for replacement (e.g.: is the appropriate type)
