Method Detail

addLoader

void addLoader(java.lang.String id,
               java.lang.String name,
               
ILoaderFactory factory,
               boolean dynamic)
Add the named loader to the manager

Parameters:
id - the loader's unique identifier string
name - a descriptive name of the loader
factory - a factory for creating an instance of the loader.
dynamic - whether the loader supports dynamic matching of file types by implementing IModelLoader.canLoad(String).

removeLoader

void removeLoader(java.lang.String id)
Remove a loader from the manager. If the loader is managed by this manager then this method has no effect.

Parameters:
id - the unique identifier of the loader to remove.

setDefaultLoader

void setDefaultLoader(java.lang.String fileType,
                      java.lang.String id)
                      throws java.lang.IllegalStateException
Define a specific loader as the default model loader for a file type.

Parameters:
fileType - the file type (extension) for which the loader is the default
id - the id of the default loader
Throws:
java.lang.IllegalStateException - if the file type already has a default loader assigned to it.

clearDefaultLoader

void clearDefaultLoader(java.lang.String fileType)
Clear the default loader (if any) associated with the file type.

Parameters:
fileType - the file type(extension) for which the loader is the default.

getModelLoader

IModelLoader getModelLoader(java.lang.String id)
Return a model loader

Parameters:
id - the unique identifier of the model loader
Returns:
the model loader, or null if not found.

getDefaultModelLoader

IModelLoader getDefaultModelLoader(java.lang.String fileType)
Return the default model loader for the given file type.

Parameters:
fileType - the file type (extension)
Returns:
the default model loader, or null if there is no default model loader.

findCompatibleModelLoaders

IModelLoaderDescription[] findCompatibleModelLoaders(java.lang.String fileType)
Return an array of model loaders that are capable of loading files of the specified type.

Parameters:
fileType - the file type (extension)
Returns:
an array of model loader descriptions. This array may be empty, but will not be null.

getDefaultModelLoaderId

java.lang.String getDefaultModelLoaderId(java.lang.String fileType)
Return the id of the default model loader for the give file type.

Parameters:
fileType - the file type (extension)
Returns:
an model loader id, or null if no loader exists.

addLoaderForType

void addLoaderForType(java.lang.String id,
                      java.lang.String fileType)
Declare the the model loader represented by id can load files of type fileType.

Parameters:
id - the model loader unique identifier.
fileType - the file type (extension).

removeLoaderForType

void removeLoaderForType(java.lang.String id,
                         java.lang.String fileType)
Forget that the model loader id can load files of type fileType.

Parameters:
id - the model loader unique identifier.
fileType - the file type (extension).

getLoader

IModelLoader getLoader(java.lang.String url,
                       java.lang.String loaderId,
                       java.lang.String type)
                       throws 
CoreJETException
Find an appropriate loader.

Parameters:
url -
loaderId -
type -
Returns:
a model loader instance.
Throws:
CoreJETException - if a loader cannot be found
