void initialize(RuntimeServices rs)

Initialize the ResourceManager.

getResource

Resource getResource(String resourceName,
                     int resourceType,
                     String encoding)
                     throws ResourceNotFoundException,
                            ParseErrorException

Gets the named resource. Returned class type corresponds to specified type (i.e. Template to RESOURCE_TEMPLATE).

Parameters:

resourceName - The name of the resource to retrieve.

resourceType - The type of resource (RESOURCE_TEMPLATE, RESOURCE_CONTENT, etc.).

encoding - The character encoding to use.

Returns:

Resource with the template parsed and ready.

Throws:

ResourceNotFoundException - if template not found from any available source.

ParseErrorException - if template cannot be parsed due to syntax (or other) error.

getLoaderNameForResource

String getLoaderNameForResource(String resourceName)

Determines is a template exists, and returns name of the loader that provides it. This is a slightly less hokey way to support the Velocity.templateExists() utility method, which was broken when per-template encoding was introduced. We can revisit this.

Parameters:

resourceName - Name of template or content resource

Returns:

class name of loader than can provide it
