Conservative Dijkstra-style write barrier that processes an object if it has not yet been processed.
params | The parameters retrieved from GetWriteBarrierType() . |
object | The pointer to the object. May be an interior pointer to a an interface of the actual object. |

Conservative Dijkstra-style write barrier that processes a range of elements if they have not yet been processed.
params | The parameters retrieved from GetWriteBarrierType() . |
first_element | Pointer to the first element that should be processed. The slot itself must reside in an object that has been allocated using MakeGarbageCollected() . |
element_size | Size of the element in bytes. |
number_of_elements | Number of elements that should be processed, starting with first_element . |
trace_callback | The trace callback that should be invoked for each element if necessary. |

Generational barrier for maintaining consistency when running with multiple generations.
params | The parameters retrieved from GetWriteBarrierType() . |
slot | Slot containing the pointer to the object. The slot itself must reside in an object that has been allocated using MakeGarbageCollected() . |

Generational barrier for source object that may contain outgoing pointers to objects in young generation.
params | The parameters retrieved from GetWriteBarrierType() . |
inner_pointer | Pointer to the source object. |

inlinestatic |
Gets the required write barrier type for a specific write.
slot | Slot containing the pointer to the object. The slot itself must reside in an object that has been allocated using MakeGarbageCollected() . |
value | The pointer to the object. May be an interior pointer to an interface of the actual object. |
params | Parameters that may be used for actual write barrier calls. Only filled if return value indicates that a write barrier is needed. The contents of the params are an implementation detail. |

inlinestatic |
Gets the required write barrier type for a specific write.
slot | Slot to some part of an object. The object must not necessarily have been allocated using MakeGarbageCollected() but can also live off-heap or on stack. |
params | Parameters that may be used for actual write barrier calls. Only filled if return value indicates that a write barrier is needed. The contents of the params are an implementation detail. |
callback | Callback returning the corresponding heap handle. The callback is only invoked if the heap cannot otherwise be figured out. The callback must not allocate. |

Gets the required write barrier type for a specific write. This version is meant to be used in conjunction with with a marking write barrier barrier which doesn't consider the slot.
value | The pointer to the object. May be an interior pointer to an interface of the actual object. |
params | Parameters that may be used for actual write barrier calls. Only filled if return value indicates that a write barrier is needed. The contents of the params are an implementation detail. |

inlinestatic |
Steele-style write barrier that re-processes an object if it has already been processed.
params | The parameters retrieved from GetWriteBarrierType() . |
object | The pointer to the object which must point to an object that has been allocated using MakeGarbageCollected() . Interior pointers are not supported. |
