void PART_LIB::AddPart

(

LIB_PART *

aPart

)

Add aPart entry to library.

Note

A LIB_PART can have an alias list so these alias will be added in library. and the any existing duplicate aliases will be removed from the library.

Parameters

aPart

- Part to add, caller retains ownership, a clone is added.

Definition at line 247 of file class_library.cpp.

References fileName, IsBuffering(), isModified, m_mod_hash, m_plugin, and m_properties.

{
    // add a clone, not the caller's copy, the plugin take ownership of the new symbol.

LIB_ALIAS * PART_LIB::RemoveAlias

(

aEntry

)

Safely remove aEntry from the library and return the next entry.

The next entry returned depends on the entry being removed. If the entry being remove also removes the part, then the next entry from the list is returned. If the entry being used only removes an alias from a part, then the next alias of the part is returned.

Parameters

aEntry

- Entry to remove from library.

Returns

The next entry in the library or NULL if the library is empty.

LIB_PART * PART_LIB::ReplacePart	(	LIB_PART *	aOldPart,

Replace an existing part entry in the library.

Note a part can have an alias list, so these alias will be added in library (and previously existing alias removed)

Parameters
