Description copied from interface: TemplateTransformModel

Returns a writer that will be used by the engine to feed the transformation input to the transform. Each call to this method must return a new instance of the writer so that the transformation is thread-safe.

Specified by:

getWriter in interface TemplateTransformModel

Parameters:

out - the character stream to which to write the transformed output

args - the arguments (if any) passed to the transformation as a map of key/value pairs where the keys are strings and the arguments are TemplateModel instances. This is never null. If you need to convert the template models to POJOs, you can use the utility methods in the DeepUnwrap class.

Returns:

a writer to which the engine will feed the transformation input, or null if the transform does not support nested content (body). The returned writer can implement the TransformControl interface if it needs advanced control over the evaluation of the transformation body.
