boolean |
evaluate(InternalContextAdapter context)
Computes boolean value of this reference
Returns the actual value of reference return type
boolean, and 'true' if value is not null
|
java.lang.Object |
execute(java.lang.Object o,
InternalContextAdapter context)
gets an Object that 'is' the value of the reference
|
java.lang.String |
getDollarBang() |
java.lang.String |
getRootString()
Returns the 'root string', the reference key
|

static java.lang.String |
printClass(java.lang.Class clazz)
Utility class to handle nulls when printing a class type
|
boolean |
render(InternalContextAdapter context,
java.io.Writer writer)
gets the value of the reference and outputs it to the
writer.
|
boolean |
setValue(InternalContextAdapter context,
java.lang.Object value)
Sets the value of a complex reference (something like $foo.bar)
Currently used by ASTSetReference()
