Method Detail

setInferredType

void setInferredType(@Nullable JTypeMirror mirror)

For a method ref or lambda, this is the type of the functional interface. E.g. in stringStream.map(String::isEmpty), this is java.util.function.Function<java.lang.String, java.lang.Boolean>

May be null if we're resetting some partial data.

Specified by:

setInferredType in interface ExprMirror

setFunctionalMethod

void setFunctionalMethod(@Nullable JMethodSig methodType)

This is the method that is overridden in getInferredType. E.g. in stringStream.map(String::isEmpty), this is java.util.function.Function<java.lang.String, java.lang.Boolean>.apply(java.lang.String) -> java.lang.Boolean

May be null if we're resetting some partial data.
