Evaluate type specified expressions with dependency values

Parameters:

expressionKind - the expression kind to indicate which type of ExpressionExecutorStrategy will be used to evaluate the expressions

expressions - a list of expressions to be evaluated

mustCheckExpressionReturnType

boolean mustCheckExpressionReturnType()

Should we throw exception if the real return type is incompatible with the declared one?

Returns:

true if an exception must be thrown if check fails, false otherwise.

mustPutEvaluatedExpressionInContext

boolean mustPutEvaluatedExpressionInContext(ExpressionKind expressionKind)

Should an expression result of a specified ExpressionKind must be put in the evaluation context?

Parameters:

expressionKind - the ExpressionKind

setExpressionExecutorStrategy

void setExpressionExecutorStrategy(List<ExpressionExecutorStrategy> expressionStrategies)
