Method Summary

Modifier and Type	Method	Description
int	getAssociateContentCount()
LinkedList<Integer>	getChildDescriptorNodes()
Vector<PSTObject>	getChildren(int numberToReturn)	get some children from the folder This is implemented as a cursor of sorts, as there could be thousands and that is just too many to process at once.

int	getContainerFlags()	Container flags Integer 32-bit signed
int	getContentCount()	the number of emails in this folder this is as reported by the PST file, for a number calculated by the library use getEmailCount
int	getFolderType()	the number of emails in this folder this is the count of emails made by the library and will therefore should be more accurate than getContentCount
PSTObject	getNextChild()	Get the next child of this folder As there could be thousands of emails, we have these kind of cursor operations
int	getSubFolderCount()	the number of child folders in this folder
Vector<PSTFolder>	getSubFolders()	get all of the sub folders...
int	getUnreadCount()	Amount of unread content items Integer 32-bit signed
boolean	hasSubfolders()	does this folder have subfolders once again, read from the PST, use getSubFolderCount if you want to know what the library makes of it all
private void	initEmailsTable()	this method goes through all of the children and sorts them into one of the three hash sets.
private void	initSubfoldersTable()
void	moveChildCursorTo(int newIndex)	move the internal folder cursor to the desired position position 0 is before the first record.
