C# Class FyreVM.Engine.Veneer

Provides hardcoded versions of some commonly used veneer routines (low-level functions that are automatically compiled into every Inform game).
Inform games rely heavily on these routines, and substituting our C# versions for the Glulx versions in the story file can increase performance significantly.

Public Methods

Method Description
ImplementsFuncGlulx ( uint slot ) : bool

Tests whether a particular function is supported for acceleration, using the codes defined in the Glulx specification.
InterceptCall ( Engine e, uint address, uint args, uint &result ) : bool

Intercepts a routine call if its address has previously been registered.
SetSlotFyre ( uint slot, uint value ) : bool

Registers a routine address or constant value, using the traditional FyreVM slot codes.
SetSlotGlulx ( Engine e, bool isParam, uint slot, uint value ) : bool

Registers a routine address or constant value, using the acceleration codes defined in the Glulx specification.

Method Details

ImplementsFuncGlulx() public method

Tests whether a particular function is supported for acceleration, using the codes defined in the Glulx specification.
public ImplementsFuncGlulx ( uint slot ) : bool
slot uint The routine index.
return bool

InterceptCall() public method

Intercepts a routine call if its address has previously been registered.
/// matches a registered veneer routine, but /// is too short for that routine. ///
public InterceptCall ( Engine e, uint address, uint args, uint &result ) : bool
e Engine The attempting to call the routine.
address uint The address of the routine.
args uint The routine's arguments.
result uint The routine's return value.
return bool

SetSlotFyre() public method

Registers a routine address or constant value, using the traditional FyreVM slot codes.
public SetSlotFyre ( uint slot, uint value ) : bool
slot uint Identifies the address or constant being registered.
value uint The address of the routine or value of the constant.
return bool

SetSlotGlulx() public method

Registers a routine address or constant value, using the acceleration codes defined in the Glulx specification.
public SetSlotGlulx ( Engine e, bool isParam, uint slot, uint value ) : bool
e Engine The for which the value is being set.
isParam bool to set a constant value; /// false to set a routine address.
slot uint The routine or constant index to set.
value uint The address of the routine or value of the constant.
return bool
