com.wewebu.expression.language.OwExprArgumentsSuffix
public class OwExprArgumentsSuffix
An function arguments suffix of a primary expression.
In the expression
function(2,3,'sss')
the (2,3,'sss')
arguments will be parsed into an OwExprArgumentsSuffix
.
At evaluation time the function
function symbol will be used to perform a function
call with the designated arguments.
