oscript.compiler.CompiledNodeEvaluator
| CompiledNodeEvaluator | | abstract public class CompiledNodeEvaluator extends NodeEvaluator (Code) | | This is the base class for all compiled script functions. I could have
used an interface, but there was no need for a compiled script function
object to subclass any other object.
A compiled function does not store the scope the script function was
defined in, but simply a compiled version of the function's syntaxtree.
This means that once a function is compiled for one scope, it does not
need to be recompiled for a different scope.

| Method Summary | |
| final protected static Value | evalHelper(String str, Scope scope)
A helper function for evaluating an EvalBlock. | | abstract public Object | evalInnerNode(int idx, StackFrame sf, Scope scope)
Evaluate, in the specified scope. | | public Object | evalNode(StackFrame sf, Scope scope)
Evaluate, in the specified scope. | | public AbstractFile | getFile()
Get the file that this node was parsed from. | | public int | getId()
Get the function symbol (name), if this node evaluator is a function,
otherwise return -1. | | abstract public SymbolTable | getInnerSharedMemberIndexTable(int idx, int perm)
Get the SMIT for the scope(s) created when invoking this node evaluator. | | public SymbolTable | getSharedMemberIndexTable(int perm)
Get the SMIT for the scope(s) created when invoking this node evaluator. | | final protected static Value | importHelper(String path, Scope scope)
A helper function for evaluating an ImportBlock. | | final public static Value | returnHelper(Value val)
A helper function for evaluating an ReturnStatement or

is not (undefined). |
| CompiledNodeEvaluator | | protected CompiledNodeEvaluator(String name, String desc)(Code) | | Class Constructor.
Parameters:
name - the name of this function
Parameters:
desc - the description of input source (ie. filename) |

Parameters:
scope - the scope to evaluate the function in the result of evaluating the function |
| evalNode | | public Object evalNode(StackFrame sf, Scope scope) throws PackagedScriptObjectException(Code) | | Evaluate, in the specified scope. If this is a function, the Arguments
to the function, etc., are defined in the scope that the
function is evaluated in.
Parameters:
sf - the stack frame to evaluate the node in
Parameters:
scope - the scope to evaluate the function in the result of evaluating the function |
| getFile | | public AbstractFile getFile()(Code) | | Get the file that this node was parsed from.
the file |
| getId | | public int getId()(Code) | | Get the function symbol (name), if this node evaluator is a function,
otherwise return -1.
