Object::DelayChanges - instance method

TEMPLATE

void DelayChanges()

SPECIFIERS

public

DESCRIPTION

Increments the delayed change message counter by one. DelayChanges is the counterpart of FlushChanges.
Hint: DelayChanges and FlushChanges are usually not called directly. The utility class DoDelayChanges is used instead that exploits automatic destruction.
An example how to use DoDelayChanges can be found in the method VObjectText::Cut and the method StyledText::Cut.
See also technote 'Change Propagation'.

none

RETURN ARGUMENT

void

FILES

KNOWN PROBLEMS

(1) Although the delayed change messages should be discarded if their sender (the observed object in question) is deleted, the current implementation does not do it. This will be fixed in future versions.

(2) Clients (and suppliers as well) have to take care that the objects referenced by a delayed change message are still living until the change message is eventually forwarded.
