Method Detail

evaluate

Object evaluate(SExpression expression,
                Map<String,Object> context,
                Map<Integer,Object> resolvedExpressions,
                ContainerState containerState)
         throws SExpressionEvaluationException,
                SExpressionDependencyMissingException

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 CONTAINER_ID_KEY and CONTAINER_TYPE_KEY

Returns:

the result of the evaluation of the expression of appropriate type

Throws:

SExpressionEvaluationException

SExpressionDependencyMissingException

validate

void validate(SExpression expression)
       throws SInvalidExpressionException

Validate the expression, an exception is thrown it is invalid

Parameters:

expression - the expression to validate

Throws:

SInvalidExpressionException - if the exception is invalid

Since:

6.0

getExpressionKind

ExpressionKind getExpressionKind()

evaluate

List<Object> evaluate(List<SExpression> expressions,
                      Map<String,Object> context,
