java.lang.Objectde.odysseus.el.tree.Tree
public class Tree
Parsed expression, usually created by a TreeBuilder
.
The bind(FunctionMapper, VariableMapper)
method is used to create
Bindings
, which are needed at evaluation time to
lookup functions and variables. The tree itself does not contain such information,
because it would make the tree depend on the function/variable mapper supplied at
parse time.
