void clear

(

)

Clears data, free buffer and reset data size.

var clear

(

)

Clears data, free buffer and reset data size.

local clear

(

)

Clears data, free buffer and reset data size.

void copy	(	const unsigned char *	bytes,
		const ssize_t	size
	)

Copies the buffer pointer and its size.

Note

This method will copy the whole buffer. Developer should free the pointer after invoking this method.

See also

Data::fastSet

var copy	(	var	bytes,
		var	size
	)

Copies the buffer pointer and its size.

Note

This method will copy the whole buffer. Developer should free the pointer after invoking this method.

See also

Data::fastSet

local copy	(	local	bytes,
		local	size
	)

Copies the buffer pointer and its size.

Note

This method will copy the whole buffer. Developer should free the pointer after invoking this method.

See also

Data::fastSet

void fastSet	(	unsigned char *	bytes,
		const ssize_t	size
	)

Fast set the buffer pointer and its size.

Please use it carefully.

Parameters

bytes

The buffer pointer, note that it have to be allocated by 'malloc' or 'calloc', since in the destructor of Data, the buffer will be deleted by 'free'.

Note

1. This method will move the ownship of 'bytes'pointer to Data,

1. The pointer should not be used outside after it was passed to this method.

See also

Data::copy

var fastSet	(	var	bytes,
		var	size
	)

Fast set the buffer pointer and its size.

Please use it carefully.

Parameters

bytes

The buffer pointer, note that it have to be allocated by 'malloc' or 'calloc', since in the destructor of Data, the buffer will be deleted by 'free'.

Note

1. This method will move the ownship of 'bytes'pointer to Data,

1. The pointer should not be used outside after it was passed to this method.

See also

Data::copy

local fastSet	(	local	bytes,
		local	size
	)

Fast set the buffer pointer and its size.

Please use it carefully.

Parameters
