class `BinaryDeltaHandler`

Inherits: IDeltaHandler

Generates and applies delta (differences) between two objects.

This handler is to be used for all native types, while a separate IDeltaHandler is to be provided for script types.

Provided object may be any IReflectable object, and special handling is done to also natively support delta between SerializedObject types.

SPtr<SerializedObject> GenerateDeltaRecursive(IReflectable *original, IReflectable *modified, ObjectMap &objectMap, RTTIOperationContext &context, bool replicableOnly) override

Recursive version of GenerateDelta(const SPtr <IReflectable > & , const SPtr <IReflectable > & , bool).

void GenerateDeltaApplyCommands(const SPtr<IReflectable> &object, const SPtr<SerializedObject> &delta, FrameAllocator &allocator, DeltaObjectMap &objectMap, FrameVector<DeltaCommand> &inOutDeltaCommands, RTTIOperationContext &context) override

Generates a set of commands that determine operations that need to be performed on in order to apply all the changes from .

Commands are output in .

void GenerateDeltaCommandForFieldEntry(RTTIType *rttiInstance, const SPtr<IReflectable> &object, RTTIIteratorField &field, const SPtr<ISerialized> &entryDelta, u32 arrayIndex, void *mapKey, DeltaObjectMap &inOutObjectMap, FrameVector<DeltaCommand> &outCommands, RTTIOperationContext &context, FrameAllocator &allocator)

Generates delta commands for a single field entry (e.g. a single array or map entry, or the entire field if not a container).

rttiInstance: RTTIType instance for the current object.
object: Object that contains the field we're applying the delta to.
field: Field to which to apply the delta to.
entryDelta: Object containing the delta value to apply.
arrayIndex: Optional array index, if the entry we're applying the value to is part of an array. Set to ~0u if not an array.
mapKey: Optional map key, if the entry we're applying the value to is part of a map. Set to null if not a map.
inOutObjectMap: Map that contains any deserialized objects so far, and into which new deserialized objects will be inserted.
outCommands: List of generated commands into which to output the commands.
context: Serialization context.
allocator: Allocator to perform temporary allocations with.

void GenerateDeltaCommandForDataBlockField(RTTIField &field, const SPtr<ISerialized> &entryDelta, FrameVector<DeltaCommand> &outCommands)

Generates delta commands for a data block field.
