Examples of com.volantis.xml.expression.Function.invoke()

com.volantis.xml.expression.Function.invoke()
Invokes the function. @param context The context within which the function is beinginvoked. @param arguments The arguments to the function specified as an array of{@link Value}s. Neither the array nor any of the arguments will be null. @return The {@link Value} that is the result of the expression, thismust never be null. @throws ExpressionException If there was a problem invoking thefunction.
