Method Summary

PsObject	duplicate() This is a shallow copy.
PsName	getTypeName() Needed for the "type" operator.

Method Detail

duplicate

PsObject duplicate()

This is a shallow copy. Specifically, composite objects should generally return themselves. Simple objects should return copies of themselves.

Returns:

A duplicate of this that conforms to what is expected by the "dup" operator.

isComposite

boolean isComposite()

The method should be overridden by composite objects.

Returns:

True iff this object is a composite PostScript object.

isExecutable

boolean isExecutable()

Indicates whether this object is executable.

Returns:

True iff this object is executable.

isComparable

boolean isComparable(PsObject object)

Test the comparability of two PSObjects. Used in the eq, ne, lt, etc. operators.

Parameters:

object - The object that should be tested for comparability.

Returns:

True if this is comparable to object, false otherwise.

getTypeName

PsName getTypeName()

Needed for the "type" operator.

Returns:

The type name as defined in PSRM2, Chapter 8, "type" operator.
