Modifier and Type	Method and Description
public ReferenceType	firstCommonSuperclass(final ReferenceType t) Deprecated use getFirstCommonSuperclass(ReferenceType t) which has slightly changed semantics. This commutative operation returns the first common superclass (narrowest ReferenceType referencing a class, not an interface).

public boolean	isAssignmentCompatibleWith(final Type t) Return true iff this is assignment compatible with another type t as defined in the JVM specification; see the AASTORE definition there.
public boolean	isCastableTo(final Type t) Return true iff this type is castable to another type t as defined in the JVM specification.

Deprecated

use getFirstCommonSuperclass(ReferenceType t) which has slightly changed semantics.

This commutative operation returns the first common superclass (narrowest ReferenceType referencing a class, not an interface). If one of the types is a superclass of the other, the former is returned. If "this" is NULL, then t is returned. If t is NULL, then "this" is returned. If "this" equals t ['this.equals(t)'] "this" is returned. If "this" or t is an ArrayType, then OBJECT is returned. If "this" or t is a ReferenceType referencing an interface, then OBJECT is returned. If not all of the two classes' superclasses cannot be found, "null" is returned. See the JVM specification edition 2, "4.9.2 The Bytecode Verifier".

public boolean isCastableTo(final Type t) throws ClassNotFoundException Return true iff this type is castable to another type t as defined in the JVM specification. The case where this is `NULL` is not defined (see the CHECKCAST definition in the JVM specification). However, because e.g. CHECKCAST doesn't throw a ClassCastException when casting a null reference to any Object, true is returned in this case.
