BlockTransformScript

Class Overview

A Block Transform Script is a textual script that specifies how to transform a given Block tree. Each "step" of this script is performed sequentially by the way of a given Block Transform (see BlockTransform). The result is either a transformed Block tree (which has the same root) or a new Block tree which may be a subset of the original Block tree or a completely newly generated result.

The process of executing a script involves two separate steps:

1. First, the textual script is parsed (see setScript(String)) and converted into an "executable" form
2. Then, it is executed on a given "root Block" (see execute(Block)).

The result of the execute call is the new root Block. At each point a checked exception may be raised:

• If the script is malformed, an BlockTransformScriptInvalid exception is raised.
• If the script fails in the process of execution, a BlockTransformExecutionFailure exception is raised.
