public Object parseExpressionString(String pExpressionString)
                             throws ELException

Description copied from class: lumis.portal.el.commonsel.ExpressionEvaluatorImpl

Gets the parsed form of the given expression string. If the parsed form is cached (and caching is not bypassed), return the cached form, otherwise parse and cache the value. Returns either a String, Expression, or ExpressionString.

Overrides:

parseExpressionString in class lumis.portal.el.commonsel.ExpressionEvaluatorImpl

Throws:

ELException

evaluate

public Object evaluate(String expressionString,
                       Class expectedType,
                       VariableResolver resolver,
                       FunctionMapper functions)
                throws ELException

Description copied from class: lumis.portal.el.commonsel.ExpressionEvaluatorImpl

Evaluates the given expression String

Overrides:

evaluate in class lumis.portal.el.commonsel.ExpressionEvaluatorImpl

Parameters:

expressionString - The expression to be evaluated.

expectedType - The expected type of the result of the evaluation

resolver - A VariableResolver instance that can be used at runtime to resolve the name of implicit objects into Objects.

functions - A FunctionMapper to resolve functions found in the expression. It can be null, in which case no functions are supported for this invocation.

Returns:

the expression String evaluated to the given expected type

Throws:

ELException
