getTypeMirror

Method Detail

getTypeMirror

@NonNull JTypeMirror getTypeMirror()

Returns the type of the functional interface. E.g. in stringStream.map(s -> s.isEmpty()), this is java.util.function.Function<java.lang.String, java.lang.Boolean>.

Specified by:

getTypeMirror in interface TypeNode

Returns:

The type mirror. Never returns null; if the type is unresolved, returns TypeSystem.UNKNOWN.

getFunctionalMethod()

getFunctionalMethod

JMethodSig getFunctionalMethod()

Returns the method that is overridden in the functional interface. E.g. in stringStream.map(s -> s.isEmpty()), this is java.util.function.Function#apply(java.lang.String) -> java.lang.Boolean
