Class DefaultSpecificationSource
java.lang.Object
|
+--com.primix.tapestry.engine.DefaultSpecificationSource
- All Implemented Interfaces:
- IRenderDescription, ISpecificationSource
- public class DefaultSpecificationSource
- extends java.lang.Object
- implements ISpecificationSource, IRenderDescription
Default implementation of ISpecificationSource
that
expects to use the normal class loader to locate component
specifications from within the classpath.
Caches specifications in memory forever, or until reset()
is invoked.
An instance of this class acts like a singleton and is shared by multiple sessions,
so it must be threadsafe.

cache

- Contains previously parsed specification.
DefaultSpecificationSource
public DefaultSpecificationSource(IResourceResolver resolver,
ApplicationSpecification specification)
reset
public void reset()
- Clears the specification cache. This is used during debugging.
- Specified by:
reset
in interface ISpecificationSource
getSpecification
public ComponentSpecification getSpecification(java.lang.String type)
throws ResourceUnavailableException
- Gets a specification. The type is either a component specification
path, or an alias to a component (registerred in the application
specification). The former always starts with a slash, the latter
never does.
If an alias (i.e, starts with a slash), then the value is passed through
ApplicationSpecification.getComponentAlias(String)
to
get a resource on the classpath that is parsed.
- Specified by:
getSpecification
in interface ISpecificationSource
- Following copied from interface:
com.primix.tapestry.ISpecificationSource
- Throws:
ResourceUnavailableException
- if the specification cannot be located or loaded.
parseSpecification
protected ComponentSpecification parseSpecification(java.lang.String resourcePath)
throws ResourceUnavailableException
