void |
bind()
verify that variables mentioned in this expression are actually available in the supplied bindings list and infer/validate the type of this expression or its subexpressions where possible |
void |
bindAssign()
bind as an assignable expression. |
void |
compile(MethodVisitor mv,
CompileContext compileContext)
|
void |
compileAssign(MethodVisitor mv,
CompileContext compileContext)
compile an assignment to the referenced location using the value on the top of the Java stack. |
java.lang.Object |
interpret(HelperAdapter helper)
evaluate the expression by interpreting the expression tree |
java.lang.Object |
interpretAssign(HelperAdapter helper,
java.lang.Object value)
execute an assignment to the referenced location by interpretation of the expression, using the object passed in this call |
Type |
typeCheck(Type expected)
ensure that all type references in the expression and its component expressions can be resolved, that the type of the expression is well-defined and that it is compatible with the type expected in the context in which it occurs. |

- the type expected for the expression in the contxet in which it occurs. this
may be void but should not be undefined at the point where type checking is performed.

helper
- an execution context associated with the rule which contains a map of
current bindings for rule variables and another map of their declared types both of which
are indexed by variable name. This includes entries for the helper (name "-1"), the
recipient if the trigger method is not static (name "0") and the trigger method arguments
(names "1", ...)
