Detailed Description

Class for iterator handlers.

An iterator handler is the object that controls the iteration process. Iterator handles are used both by the collection classes and the browser classes.

The most important method in this class is the Iterate() method; overide this method in child classes to provide new iterator functionality.

Although you can use this class without creating a child class, such an iterator object would not provide any functionality.

◆ FCIteratorHandler()

FCIteratorHandler::FCIteratorHandler	(	bool	bUseProgressBar = false,
		bool	bUserAbortable = false )

inline

The constructor.

Parameters

bUseProgressBar	Set to true if a progress bar should be displayed during processing.
bUserAbortable	Set to true if a the progress bar process should be abortable by the user (pressing the Escape key).

This method is called even if the list of objects is empty.

Currently supported by FCBrowserNoteEntries.

◆ PostProcessIfExist()

virtual void FCIteratorHandler::PostProcessIfExist ( )

Currently supported by FCBrowserNoteEntries.

◆ PreProcessIfExist()

virtual bool FCIteratorHandler::PreProcessIfExist ( )

inlinevirtual

A virtual callback that can be used for preprocessing before any objects are processed, but only if there are objects to iterate.

Returns: Return true if it's ok to continue to iterate through the objects. Return false to don't process any objects.

Currently supported by FCBrowserNoteEntries.

◆ SecondPassIterate()

virtual bool FCIteratorHandler::SecondPassIterate ( __FCBase * pObject )

inlinevirtual

A second-pass virtual callback method when iterating through multiple objects.

This method can be of use if a second pass is required for auto-loaded/saved data collections.

Currently supported by FCBrowserNoteEntries

Returns: Return true if the iteration process should continue to the next object in the list. Return false if no more objects should be processed. By default, this method returns false - indicating that no data should be processed twice.

◆ SetLastAbortState()

void FCIteratorHandler::SetLastAbortState ( bool value )

inline

For internal use only! Sets the latest abort state.

Parameters

value The new value.

◆ SetProgressBarAbortable()

void FCIteratorHandler::SetProgressBarAbortable ( bool value )

inline

Sets the current state of the setting for being able the abort the progress bar processing.

This value value can also be set in the constructor.

◆ SetSaveAfterIterate()

void FCIteratorHandler::SetSaveAfterIterate ( bool value )

inline

Set the state that the iterator wants the caller to automatically save the data after the Iterate call. This feature might NOT be supported by the caller!

Please refer to the documentation for the caller class (browser or collection) to see if the feature is supported.

Parameters

value True to flag that data should be automatically saved.

◆ SetUseProgressBar()

void FCIteratorHandler::SetUseProgressBar ( bool value )

inline

Sets the current state of the setting for using the progress bar.

This value value can also be set in the constructor.
