 Map<Integer,Object> resolvedExpressions,
 ContainerState containerState)
                throws SExpressionEvaluationException

Specified by:

evaluate in interface ExpressionExecutorStrategy

Parameters:

expression - the expression to evaluate

context - map containing the result of the evaluation of dependencies and also informations about the context of evaluation given by ExpressionExecutorStrategy.CONTAINER_ID_KEY and ExpressionExecutorStrategy.CONTAINER_TYPE_KEY

Returns:

the result of the evaluation of the expression of appropriate type

Throws:

SExpressionEvaluationException

onUpdate

public void onUpdate(ClassLoader newClassLoader)

Specified by:

onUpdate in interface SingleClassLoaderListener

onDestroy

public void onDestroy(ClassLoader oldClassLoader)

Specified by:

onDestroy in interface SingleClassLoaderListener

getExpressionKind

public ExpressionKind getExpressionKind()

Specified by:

getExpressionKind in interface ExpressionExecutorStrategy

evaluate

coerceResult

protected Object coerceResult(groovy.lang.GroovyShell shell,
 Object result,
 String returnType)
                       throws ClassNotFoundException,
SCacheException

Execute a Groovy expression that coerce the result into the returnType

Parameters:

shell - , the Groovy shell use for script evaluation

result - , the evaluation result

returnType - , expected expression return type

Returns:

the result with the expected type or a GroovyCastException if the coercion fails

Throws:
