loadModel

public abstract ASMModel loadModel(String name,
 ASMModel metamodel,
 InputStream in)
                            throws IOException

Loads a model with given name and metamodel from in. Use this method only if there is no real URI available!

Parameters:

name - The model name.

metamodel - The metamodel of the model to be loaded.

in - The input stream from which to load.

Returns:

The loaded ASMModel.

Throws:

IOException

realLoadModel

protected abstract ASMModel realLoadModel(String name,
 ASMModel metamodel,
 String href)
                                   throws IOException

Throws:

IOException

loadModel

public ASMModel loadModel(String name,
 ASMModel metamodel,
 String href)
                   throws IOException

Loads a model from the URI represented by href.

Parameters:

name - The model name.

metamodel - The metamodel of the model to be loaded.

href - The model URI.

Returns:

The loaded ASMModel.

Throws:

IOException

inject

public ASMModelElement inject(ASMModel ret,
 String kind,
 String params,
 String uri,
