◆ LoadCompactBinary()

FCbField LoadCompactBinary	(	FArchive &	Ar,
		FCbBufferAllocator	Allocator = FUniqueBuffer::Alloc )

Load a compact binary field from an archive.

The field may be an array or an object, which the caller can convert to by using AsArray or AsObject as appropriate. The buffer allocator is called to provide the buffer for the field to load into once its size has been determined.

Parameters

Ar	Archive to read the field from. An error state is set on failure.
Allocator	Allocator for the buffer that the field is loaded into.

Returns: A field with a reference to the allocated buffer, or a default field on failure.

◆ LoadFromCompactBinary() [10/20]

bool LoadFromCompactBinary	(	FCbFieldView	Field,

LoadFromCompactBinary attempts to load the output value from compact binary.

Implementations of LoadCompactBinary are expected to assign the output even on failure. Implementations may accept an optional default value to assign in case of load failure.

Returns: true if required fields had the values with the correct type and range, otherwise false.

◆ MeasureCompactBinary()

uint64 MeasureCompactBinary	(	FMemoryView	View,
		ECbFieldType	Type = ECbFieldType::HasFieldType )

Determine the size in bytes of the compact binary field at the start of the view.

This may be called on an incomplete or invalid field, in which case the returned size is zero. A size can always be extracted from a valid field with no name if a view of at least the first 10 bytes is provided, regardless of field size. For fields with names, the size of view needed to calculate a size is at most 10 + MaxNameLen + MeasureVarUInt(MaxNameLen).

This function can be used when streaming a field, for example, to determine the size of buffer to fill before attempting to construct a field from it.

Parameters

View	A memory view that may contain the start of a field.
Type	HasFieldType means that View contains the type. Otherwise, use the given type.

◆ operator<<() [1/3]

FArchive & operator<<	(	FArchive &	Ar,
		FCbArray &	Array )

◆ operator<<() [2/3]

FArchive & operator<<	(	FArchive &	Ar,
		FCbField &	Field )

Serialize a compact binary value to/from an archive.

◆ operator<<() [3/3]

FArchive & operator<<	(	FArchive &	Ar,
		FCbObject &	Object )

◆ SaveCompactBinary() [1/3]

void SaveCompactBinary	(	FArchive &	Ar,
		const FCbArrayView &	Array )

◆ SaveCompactBinary() [2/3]

void SaveCompactBinary	(	FArchive &	Ar,
		const FCbFieldView &	Field )

Save a compact binary value to an archive.

◆ SaveCompactBinary() [3/3]

void SaveCompactBinary	(	FArchive &	Ar,
		const FCbObjectView &	Object )

◆ TryMeasureCompactBinary()

bool TryMeasureCompactBinary	(	FMemoryView	InView,
		ECbFieldType &	OutType,
		uint64 &	OutSize,
		ECbFieldType	InType = ECbFieldType::HasFieldType )

Try to determine the type and size of the compact binary field at the start of the view.

This may be called on an incomplete or invalid field, in which case it will return false, with OutSize being 0 for invalid fields, otherwise the minimum view size necessary to make progress in measuring the field on the next call to this function.

Note: A return of true from this function does not indicate that the entire field is valid.

Parameters

InView	A memory view that may contain the start of a field.
OutType	The type (with flags) of the field. None is written until a value is available.
OutSize	The total field size for a return of true, 0 for invalid fields, or the size to make progress in measuring the field on the next call to this function.
InType	HasFieldType means that InView contains the type. Otherwise, use the given type.

Returns: true if the size of the field was determined, otherwise false.
