Method Detail

isNoTypeExpectation

public boolean isNoTypeExpectation()

Description copied from interface: ITypeExpectation

Returns true if anything is allowed and no constraints are expected.

Returns:

true if anything is allowed and no constraints are expected.

getExpectedType

public JvmTypeReference getExpectedType()

Description copied from interface: ITypeExpectation

Returns the expected type. The expected type may be not too concrete thus ITypeExpectation.getExpectedType() may return null or some sort of unresolved, specialized reference. If null is returned, clients may want to check ITypeExpectation.isNoTypeExpectation() or ITypeExpectation.isVoidTypeAllowed().

Returns:

the expected type. This may be null.
