Constructor & Destructor Documentation

◆ MutableData()

Murl::MutableData::MutableData	(	void *	data,
		UInt64	byteSize
	)

inline

The constructor taking data and byte size.

Parameters

data	Pointer to the memory data location.
byteSize	Byte size of the memory data location.

Member Function Documentation

◆ GetMutableData() [1/4]

template<class DataType >

DataType* Murl::MutableData::GetMutableData ( ) const

inline

Get the pointer to the mutable memory data location.

Template Parameters

DataType The type of the returned pointer.

Returns: The pointer to the mutable memory data location.

◆ GetMutableData() [2/4]

UInt8* Murl::MutableData::GetMutableData ( ) const

inline

Get the pointer to the mutable memory data location.

Returns: The pointer to the mutable memory data location.

◆ GetMutableData() [3/4]

template<class DataType >

DataType* Murl::MutableData::GetMutableData ( UInt64 byteOffset ) const

inline

Get the pointer to the mutable memory data location including a byte offset.

A valid byte offset is in range [0 .. GetByteSize() - 1].

Template Parameters

DataType The type of the returned pointer.

Parameters

byteOffset The byte offset.

Returns: The pointer to the mutable memory data location or null if the byte offset is out of range.

◆ GetMutableData() [4/4]

UInt8* Murl::MutableData::GetMutableData ( UInt64 byteOffset ) const

inline

Get the pointer to the mutable memory data location including a byte offset.

A valid byte offset is in range [0 .. GetByteSize() - 1].

Parameters

byteOffset The byte offset.

Returns: The pointer to the mutable memory data location or null if the byte offset is out of range.

◆ CopyDataTo()

UInt64 Murl::MutableData::CopyDataTo	(	MutableData &	destination,
		UInt64	byteOffset
	)		const

inline

Copy the memory data to a destination data object.

The destination data object must have already assigned memory. A valid byte offset is in range [0 .. GetByteSize() - 1].

Parameters

destination	The the destination data object.
byteOffset	The source byte offset.

Returns: The number of bytes copied to the destination.

References Murl::ConstData::CopyTo().

◆ CopyFrom()

UInt64 Murl::MutableData::CopyFrom	(	const void *	source,
		UInt64	byteSize,
		UInt64	byteOffset
	)		const

inline

Copy the memory data from a source memory location.

The data object must have already assigned memory. A valid byte offset is in range [0 .. GetByteSize() - 1].

Parameters

source	The pointer to the source memory.
byteSize	The source byte size.
byteOffset	The destination byte offset.

Returns: The number of bytes copied to the destination.

◆ CopyDataFrom()

UInt64 Murl::MutableData::CopyDataFrom	(	const ConstData &	source,
		UInt64	byteOffset
	)		const

inline

Copy the memory data from a source data object.

The data object must have already assigned memory. A valid byte offset is in range [0 .. GetByteSize() - 1].

Parameters

source	The source data object.
byteOffset	The destination byte offset.

Returns: The number of bytes copied to the destination.
