Class RecompilingTemplateManager

java.lang.Object
  org.jamon.RecompilingTemplateManager

All Implemented Interfaces:

TemplateManager

public class RecompilingTemplateManager
extends Object
implements TemplateManager

An implementation of the TemplateManager interface which supports dynamic regeneration and recompilation of templates as they are changed, much as JSP does. RecompilingTemplateManager instances are thread-safe. In your applications, you generally want exactly one instance of a RecompilingTemplateManager (i.e. a singleton). Configuration of a RecompilingTemplateManager occurs only at construction time, and is determined by the RecompilingTemplateManager.Data object passed to the constructor. The properties on the Data are:

• setSourceDir - determines where the RecompilingTemplateManager looks for template source files. Default is the current directory, which is most likely unsuitable for most situations.
• setWorkDir - determines where the generated Java source files corresponding to templates are placed. Default is uniquely generated subdirectory under the directory specified by the system property java.io.tmpdir.
• setJavaCompiler - determines what program to execute to compile the generated Java source files. Default is bin/javac under the directory specified by the system property java.home.
• setClasspath - used to specify additional components to prepend to the classpath when compiling generated Java source files. Default is null.
• setClassLoader - used to set the class loader explicitly. Default is use the class loader of the RecompilingTemplateManager instance.
