Class CodeTemplateManager

java.lang.Object
  org.fife.ui.rsyntaxtextarea.CodeTemplateManager

public class CodeTemplateManager
extends java.lang.Object

Manages "code templates."

All methods in this class are synchronized for thread safety, but as a best practice, you should probably only modify the templates known to a CodeTemplateManager on the EDT. Modifying a CodeTemplate retrieved from a CodeTemplateManager while not on the EDT could cause problems.

For more flexible boilerplate code insertion, consider using the TemplateCompletion class in the AutoComplete add-on library.
