Method Detail

equal

public static boolean equal(java.lang.Object anObject,
                            java.lang.Object anotherObject)

Computes the equivalence of two objects, accounting for primitive numeric values that OCL considers equal but Java does not. This is also safe when either value is null.

Parameters:

anObject - an object or null

anotherObject - another object or null

Returns:

whether they are equivalent as far as OCL is concerned

hashCode

public static int hashCode(java.lang.Object anObject)

Computes hash of an object, accounting for the similar hashing of primitive numeric values that OCL considers equal but Java does not. It is also safe with null values.

Parameters:

anObject - an object or null

Returns:

its OCL hash

isPrimitive

public static boolean isPrimitive(java.lang.Object o)

Queries whether the specified object represents an OCL primitive value.

Parameters:

o - an object

Returns:

whether it is an OCL primitive value

dispose

public static void dispose(java.lang.Object object)

Disposes of the specified object. If, in particular, it is an EObject, then it and all of its contents will have their adapter-lists cleared.

Parameters:

object - an object to dispose
