- All Implemented Interfaces:
- ClassDeclarationPhase, Generator, InitMethodPhase
- public class TagPoolGenerator
- extends org.apache.jasper.compiler.GeneratorBase
- implements ClassDeclarationPhase, InitMethodPhase
This class generates tag pooling related information. Specifically,
it generates code to declare tag pools and to obtain tag pools
during jsp initialization.
