| ASTArrayAccess | | public ASTArrayAccess(int id)(Code) | | Create the node given an id.
Parameters:
id - node id. |
| ASTArrayAccess | | public ASTArrayAccess(Parser p, int id)(Code) | | Create a node with the given parser and id.
Parameters:
p - a parser.
Parameters:
id - node id. |
| evaluateExpr | | public static Object evaluateExpr(Object o, Object loc) throws Exception(Code) | | Evaluate the Array expression 'loc' on the given object, o.
e.g. in 'a[2]', 2 is 'loc' and a is 'o'.
If o or loc are null, null is returned.
If o is a Map, o.get(loc) is returned.
If o is a List, o.get(loc) is returned. loc must resolve to an int value.
If o is an Array, o[loc] is returned. loc must resolve to an int value.
Otherwise loc is treated as a bean property of o.
Parameters:
o - an object to be accessed using the array operator or '.' operator.
Parameters:
loc - the index of the object to be returned. the resulting value.
throws:
Exception - on any error. |
| execute | | public Object execute(Object obj, JexlContext jc) throws Exception(Code) | | evaluate array access upon a base object.
foo.bar[2]
makes me rethink the array operator :)
Parameters:
jc - the JexlContext to evaluate against.
Parameters:
obj - not used. the value of the array expression.
throws:
Exception - on any error |
| getIdentifierString | | public String getIdentifierString()(Code) | | Gets the variable name piece of the expression.
