Detailed Description

Data structure to hold a block of raw data.

This is basically a stripped down std::vector. It contains a contiguous block of memory with two sizes associated with it. The reserve indicates how much data is actually allocated while the size tells us how much of the data is relevant. The motivation for this as opposed to a vector is that this lacks element initialization.

Block() [1/5]

Fastcgipp::Block::Block

(

)

Initialize an empty block.

Definition at line 50 of file block.cpp.

Block() [2/5]

Fastcgipp::Block::Block

(

const size_t

size_

)

Initialize a block with equal size and reserve.

Definition at line 55 of file block.cpp.

Block() [3/5]

Fastcgipp::Block::Block	(	const char *const	data,
		const size_t	size_
	)

Initialize a block with equal size and reserve from source data.

Member Function Documentation

assign()

void Fastcgipp::Block::assign	(	const char *const	data,
		const size_t	size_
	)

Assign a sequence a data to the block.

If the reserve if smaller the requested size then reallocation occurs. Otherwise the allocation is unchanged.

Definition at line 105 of file block.cpp.

begin() [1/2]

char* Fastcgipp::Block::begin ( )

inline

Pointer to the first element.

Definition at line 103 of file block.hpp.

begin() [2/2]

const char* Fastcgipp::Block::begin ( ) const

inline

Constant pointer to the first element.

Definition at line 109 of file block.hpp.

References m_data.

clear()

void Fastcgipp::Block::clear

(

)

Deallocate memory and set size and reserve to zero.

Definition at line 98 of file block.cpp.

end() [1/2]

char* Fastcgipp::Block::end ( )

inline

Pointer to 1+ the last element.

Definition at line 115 of file block.hpp.

References m_data, and m_size.

Referenced by Fastcgipp::FcgiStreambuf< charT >::emptyBuffer(), Fastcgipp::Manager_base::localHandler(), and Fastcgipp::Transceiver::transmit().

end() [2/2]

const char* Fastcgipp::Block::end ( ) const

inline

Constant pointer to 1+ the last element.

Definition at line 121 of file block.hpp.

References m_data, and m_size.

operator=() [1/2]

Fastcgipp::Block & Fastcgipp::Block::operator=

(

Block &&

x

)

Steal the data from another block.

Definition at line 78 of file block.cpp.

References m_reserve.

operator=() [2/2]

Block& Fastcgipp::Block::operator= ( const Block &  )

delete

reserve() [1/2]

size_t Fastcgipp::Block::reserve ( ) const

inline

See the reserve size.

Definition at line 80 of file block.hpp.

References m_reserve.

reserve() [2/2]

void Fastcgipp::Block::reserve

(

size_t

x

)

Set the reserve size.

Unlike std::vector this always obeys your command even if you are decreasing the reserve size. All data is copied over when a reserve is changed.

Definition at line 32 of file block.cpp.

size_t Fastcgipp::Block::size ( ) const

size() [2/2]

void Fastcgipp::Block::size

(

size_t

x

)

Set the relevant data size.
