Method Detail

getExpressionDfaValue

public DfaValue getExpressionDfaValue(PsiExpression expression)

getQualifierOrThisValue

public DfaValue getQualifierOrThisValue(PsiReferenceExpression refExpr)

Returns a DFA variable which represents the qualifier for given reference if possible. For unqualified reference to a non-static member, a variable which represents the corresponding this may be returned

Parameters:

refExpr - reference to create a qualifier variable for

Returns:

a qualifier variable or null if qualifier is unnecessary or cannot be represented as a variable
