Making your code run faster

Two simple coding practices can make a plug-in or OpenModel application run faster. These ideas are stated elsewhere in the API documentation but are worth repeating here. Adhering to these coding practices are even more important if your code will be dealing with large numbers of objects.

• Where possible, utilize the destructive wrapper methods such as nextD() or prevD() to iterate over objects. The destructive methods re-use the wrapper object so no memory allocation and destruction needs to be performed to iterate to another object.
• Turn off updating until you have finished a batch of changes. Many classes contain a doUpdates( boolean newState ) method. Before going into a batch of geometry changes, call doUpdates( FALSE ) to turn off updating. After the batch of geometry changes, call doUpdates( TRUE ) to update any changed object.

An additional coding practice that can be utilized is wherever possible takes advantage of methods that perform operations on multiple objects. Some of the batch routines are described above. These include creating and deleting keyframes.
