public GUID()

Default no-arg constructor

Method Detail

isNull

public abstract boolean isNull()

check if GUID is null. GUID 0.0.0.0 is null.

Returns:

true if this is a null GUID.

setNull

public abstract void setNull()

getModuleName

public java.lang.String getModuleName()

IDL-generated helper routine to get module name (currently unimplemented).

Overrides:

getModuleName in class Object

Returns:

name of this class's module

equals

public boolean equals(java.lang.Object c)

Standard IDL-generated equality test.

Overrides:

equals in class ValueBase

Parameters:

c - The object to be compared against this.

Returns:

true if this is equal to c

_equals_helper

public boolean _equals_helper(GUID c)

Internal IDL-generated equality test helper

matches

public boolean matches(java.lang.Object c)

Standard IDL-generated template match test.

Overrides:

matches in class ValueBase

Parameters:

c - The object to be checked against this template.

Returns:

true if this (as a template) matches the argument

_matches_helper

public boolean _matches_helper(GUID c)

Internal IDL-generated match test helper

writeObject
