inline explicit ScriptContext (const char* name = 0)
| ScriptContext |
Constructor
Parameters:
name | Name of the context |
inline NamedList& params ()
| params |

Returns: Pointer to a native named list
const String& toString ()
| toString |
[const virtual]
Override GenObject's method to return the internal name of the named list
Returns: A reference to the context name
Reimplemented from GenObject.
void* getObject (const String& name)

[static]
Fill a list with the unique names of all fields
Parameters:
names | List to which key names must be added |
list | List of parameters whose names to be added |
skip | Parameters starting with this prefix will not be added |
bool runFunction (ObjList& stack, const ExpOperation& oper, GenObject* context)
| runFunction |
[virtual]
Try to evaluate a single function in the context
Parameters:
stack | Evaluation stack in use, parameters are popped off this stack and results are pushed back on stack |

bool runAssign (ObjList& stack, const ExpOperation& oper, GenObject* context)
| runAssign |
[virtual]
Try to assign a value to a single field
Parameters:
stack | Evaluation stack in use |
oper | Field to assign to, contains the field name and new value |
context | Pointer to context data passed from evaluation methods |
Returns: True if assignment succeeded
Reimplemented from ExpExtender.
bool copyFields (ObjList& stack, const ScriptContext& original, GenObject* context)
| copyFields |
[virtual]
Copy all fields from another context
Parameters:
stack | Evaluation stack in use |
original | Script context to copy from |
context | Pointer to context data passed from evaluation methods |
Returns: True if all fields were copied
bool runMatchingField (ObjList& stack, const ExpOperation& oper, GenObject* context)
| runMatchingField |
