Detailed Description

Value wraps an object pointer.

It is responsible for informing the garbage collector that the object is referenced outside of the GC'd heap and so should not be deallocated.

Note that the GC tracks the stack, so it is not necessary to use this class for object pointers stored purely on the stack.

Value() [2/4]

Interpreter::Value::Value ( Obj  o )

inline

Construct a new value from an object pointer.

Definition at line 61 of file interpreter.hh.

Member Function Documentation

address()

Obj* Interpreter::Value::address ( )

inline

Returns the address of the object.

This is used so that the storage can be used for values in a symbol table. All globals are handled by creating an instance of this class and then adding the address to the symbol table.

Definition at line 50 of file interpreter.hh.

getIntValue()

int Interpreter::Value::getIntValue ( )

inline

Returns the integer value of this object, if it is a small integer.

Definition at line 94 of file interpreter.hh.

Here is the call graph for this function:

isInteger()

bool Interpreter::Value::isInteger ( )

inline

Returns true if this object is a small integer, false otherwise.

Definition at line 87 of file interpreter.hh.

Here is the caller graph for this function:

operator Obj()

Interpreter::Value::operator Obj ( )

inline

Definition at line 80 of file interpreter.hh.

operator=() [1/2]

void Interpreter::Value::operator= ( Obj  o )

inline

Definition at line 78 of file interpreter.hh.

operator=() [2/2]

void Interpreter::Value::operator= ( Value &  o )

inline

Definition at line 79 of file interpreter.hh.
