execute

public Object execute(ScriptEngine scriptEngine,
 VariableScope variableScope,

Evaluates the script using the provided engine and bindings

Parameters:

scriptEngine - the script engine to use for evaluating the script.

variableScope - the variable scope of the execution

bindings - the bindings to use for evaluating the script.

Returns:

the result of the script evaluation

Throws:

ProcessEngineException - in case the script cannot be evaluated.

getActivityIdExceptionMessage

protected String getActivityIdExceptionMessage(VariableScope variableScope)

evaluate

protected abstract Object evaluate(ScriptEngine scriptEngine,
 VariableScope variableScope,
 Bindings bindings)

preprocessScript

protected String preprocessScript(String script,
 VariableScope variableScope)

Preprocesses a script before execution.

If script preprocessing is disabled, no preprocessor is configured, or the preprocessor returns null, the original script is returned unchanged.

If preprocessing fails with an exception, a warning is logged and the original script is returned as a safe fallback to ensure scripts continue to execute.

Parameters:

script - the script text to preprocess; may be null

variableScope - the current execution context; may be null

Returns:

the preprocessed script, or the original script if preprocessing is disabled, not configured, returns null, or fails with an exception
