## Member Function Documentation

virtual int asIScriptFunction::AddRef | ( |  | ) | `[pure virtual]`

Returns:
  The number of references to this object.

Call this method when storing an additional reference to the object.

virtual asDWORD* asIScriptFunction::GetByteCode | ( | asUINT * | length = `0` | ) | `[pure virtual]`

Parameters:

  `[out]` | length | The length of the byte code buffer in DWORDs

Returns:
  A pointer to the byte code buffer, or 0 if this is not a script function.

This function is used by the asIJITCompiler to obtain the byte code buffer for building the native machine code representation.

virtual const char* asIScriptFunction::GetConfigGroup | ( |  | ) | const`[pure virtual]`

Returns:
  The name of the config group, or null if not in any group.

virtual const char* asIScriptFunction::GetDeclaration | ( | bool | includeObjectName = `true` | ) | const`[pure virtual]`

Parameters:

  `[in]` | includeObjectName | Indicate whether the object name should be prepended to the function name

Returns:
  A null terminated string with the function declaration.

virtual asIScriptEngine* asIScriptFunction::GetEngine | ( |  | ) | const`[pure virtual]`

Returns:
  A pointer to the engine.

virtual int asIScriptFunction::GetId | ( |  | ) | const`[pure virtual]`

Returns:
  The id of the function

virtual const char* asIScriptFunction::GetModuleName | ( |  | ) | const`[pure virtual]`

Returns:
  A null terminated string with the module name.

virtual const char* asIScriptFunction::GetName | ( |  | ) | const`[pure virtual]`

Returns:
  A null terminated string with the name of the function.

virtual const char* asIScriptFunction::GetObjectName | ( |  | ) | const`[pure virtual]`

Returns:
  A null terminated string with the name of the object type if this a method.

virtual asIObjectType* asIScriptFunction::GetObjectType | ( |  | ) | const`[pure virtual]`

Returns:
  A pointer to the object type interface if this is a method.

virtual int asIScriptFunction::GetParamCount | ( |  | ) | const`[pure virtual]`

Returns:
  The number of parameters.

virtual int asIScriptFunction::GetParamTypeId | ( | int | index,
|  | asDWORD * | flags = `0` |
| ) |  |  | const`[pure virtual]`

Parameters:

  `[in]` | index | The zero based parameter index.
  `[out]` | flags | A combination of asETypeModifiers.

Returns:
  A negative value on error, or the type id of the specified parameter.

Return values:

  | asINVALID_ARG | The index is out of bounds.

virtual int asIScriptFunction::GetReturnTypeId | ( |  | ) | const`[pure virtual]`

Returns:
  The type id of the return type.

virtual const char* asIScriptFunction::GetScriptSectionName | ( |  | ) | const`[pure virtual]`

Returns:
  A null terminated string with the script section name where the function was implemented.

virtual bool asIScriptFunction::IsClassMethod | ( |  | ) | const`[pure virtual]`

Returns:
  True if this a class method.

virtual bool asIScriptFunction::IsInterfaceMethod | ( |  | ) | const`[pure virtual]`

Returns:
  True if this is an interface method.

virtual bool asIScriptFunction::IsReadOnly | ( |  | ) | const`[pure virtual]`

Returns:
  True if the class method is read-only

virtual int asIScriptFunction::Release | ( |  | ) | `[pure virtual]`

Returns:
  The number of references to this object.

Call this method when you will no longer use the references that you own.
