Method Detail

getQualifierType

PsiTypeElement getQualifierType()

Returns the type element used as the qualifier of the reference.

Returns:

the qualifier, or null if the reference is qualified by expression.

isExact

boolean isExact()

Returns:

if there is only one possible compile-time declaration with only one possible invocation type, regardless of the targeted function type return true, false otherwise

isPotentiallyCompatible

boolean isPotentiallyCompatible(PsiType functionalInterfaceType)

15.12.2.1 Identify Potentially Applicable Methods ................................................. A method reference (15.13) is potentially compatible with a functional interface type if, where the type's function type arity is n, there exists at least one potentially-applicable method for the method reference at arity n (15.13.1), and one of the following is true: The method reference has the form ReferenceType::NonWildTypeArgumentsOpt Identifier and at least one potentially-applicable method either i) is declared static and supports arity n, or ii) is not declared static and supports arity n-1. The method reference has some other form and at least one potentially-applicable method is not declared static.

Specified by:

isPotentiallyCompatible in interface PsiFunctionalExpression

getPotentiallyApplicableMember

PsiMember getPotentiallyApplicableMember()

Returns:

potential applicable member for exact reference, otherwise null

isConstructor

boolean isConstructor()

Returns:

true if reference is of form ClassType::new

isAcceptable

boolean isAcceptable(PsiType left,
                     PsiMethod method)

Potentially compatible, and if exact - congruent

Specified by:

isAcceptable in interface PsiFunctionalExpression

Returns:

true if assignment SAM s = expr is correctly shaped
