                                         String resource,
                                         ExpressionManager expressionManager)

Creates a new ExecutableScript from a source or resource. It excepts static and dynamic sources and resources. Dynamic means that the source or resource is an expression which will be evaluated during execution.

Parameters:

language - the language of the script

source - the source code of the script or an expression which evaluates to the source code

resource - the resource path of the script code or an expression which evaluates to the resource path

expressionManager - the expression manager to use to generate the expressions of dynamic scripts

Returns:

the newly created script

Throws:

NotValidException - if language is null or empty or both of source and resource are null or empty

getScript

scriptFactory - the script factory used to create the script

Returns:

the newly created script

Throws:

NotValidException - if language is null or empty or both of source and resource are invalid

                                                   String source,
                                                   ScriptFactory scriptFactory)

Creates a new ExecutableScript from a static source.

Parameters:
