Detailed Description

Manages a binary object of arbitrary length.

The data block is allocated with malloc() instead of the new operator so that we can use realloc() to resize it.

Constructor & Destructor Documentation

Blob::Blob	(	const uint8_t *	data,
		unsigned	length
	)

Constructor.

Makes a local copy of the data argument.

Blob::Blob

(

const Blob &

other

)

Copy constructor.

Makes a local copy of the data owned by other.

Blob::~Blob ( )

virtual

Destructor.

Disposes of the binary data associated with this object.

Member Function Documentation

void Blob::setData	(	const uint8_t *	data,
		unsigned	length
	)

Replaces the blob's data.

Copies data onto the blob's data. The blob does not assume ownership of data.

Parameters

data	Pointer to a buffer containing the data which will be copied into the blob.
length	Number of bytes pointed to by data.

void Blob::setLength

(

unsigned

length

)

Change the size of the blob's data.

Sets the m_length member variable to length and resizes m_data to the new length. The contents of m_data past any previous contents are undefined. If the new length is 0 then the data will be freed and a subsequent call to getData() will return NULL.

Parameters

length

New length of the blob's data in bytes.
