Detailed Description

A simple buffer of bytes.

This class is fully inlined and just aiming to provide RIIA and unified view of memory buffers. It is a kind of a std::vector with a reduced interface in the intentions of the author.

Constructor & Destructor Documentation

SimpleBuffer() [1/3]

gnash::SimpleBuffer::SimpleBuffer ( size_t  capacity = 0 )

inline

Construct a SimpleBuffer with an optional initial capacity.

Parameters

capacity

The initial buffer capacity. This is the amount of bytes you can append to the buffer before a new reallocation will occur.

References gnash::key::b, and operator=().

SimpleBuffer() [2/3]

gnash::SimpleBuffer::SimpleBuffer ( SimpleBuffer &&  )

default

Move constructor.

SimpleBuffer() [3/3]

gnash::SimpleBuffer::SimpleBuffer ( const SimpleBuffer &  b )

delete

Copy (construction) not allowed.

Member Function Documentation

append() [1/2]

void gnash::SimpleBuffer::append ( const void *  inData, size_t  size  )

inline

Append data to the buffer.

The buffer will be appropriately resized to have space for the incoming data. The data will be copied.

Parameters

inData	Data to append. Will be copied.
size	Size of data to append

References resize().

Referenced by append(), gnash::registerSharedObjectNative(), gnash::amf::writePlainNumber(), and gnash::amf::writePlainString().

append() [2/2]

void gnash::SimpleBuffer::append ( const SimpleBuffer &  buf )

inline

Append data to the buffer.

The buffer will be appropriately resized to have space for the incoming data. The data will be copied.

Parameters

buf	SimpleBuffer containing data to append

References append(), data(), and size().

appendByte()

void gnash::SimpleBuffer::appendByte ( const std::uint8_t  b )

inline

Append a byte to the buffer.

The buffer will be appropriately resized to have space.

Parameters

b	Byte to append.

References gnash::key::b, and resize().

Referenced by replyBWCheck(), sendCheckBW(), sendConnectPacket(), sendCreateStream(), sendDeleteStream(), sendFCSubscribe(), sendPausePacket(), and gnash::amf::write().

appendNetworkLong()

void gnash::SimpleBuffer::appendNetworkLong ( const std::uint32_t  l )

inline

Append 4 bytes to the buffer.

The buffer will be appropriately resized to have space.

Parameters

l	Long to append. Will be appended in network order. ie with high order bytes first.

References resize().

Referenced by gnash::registerSharedObjectNative(), gnash::rtmp::sendCtrl(), gnash::rtmp::sendServerBW(), and gnash::amf::writePlainString().

appendNetworkShort()

void gnash::SimpleBuffer::appendNetworkShort ( const std::uint16_t  s )

inline

Append 2 bytes to the buffer.

The buffer will be appropriately resized to have space.

Parameters

s	Short to append. Will be appended in network order. ie with high order byte first.

References resize().

Referenced by gnash::registerSharedObjectNative(), gnash::rtmp::sendCtrl(), and gnash::amf::writePlainString().

capacity()

size_t gnash::SimpleBuffer::capacity ( ) const

inline

Return capacity of the buffer.

data() [1/2]

std::uint8_t* gnash::SimpleBuffer::data ( )

inline

data() [2/2]

const std::uint8_t* gnash::SimpleBuffer::data ( ) const

inline

Get a pointer to start of data. May be NULL if size==0.

empty()

bool gnash::SimpleBuffer::empty ( ) const

inline

Return true if buffer is empty.

operator=() [1/2]

SimpleBuffer& gnash::SimpleBuffer::operator= ( const SimpleBuffer &  b )

delete

operator=() [2/2]

SimpleBuffer& gnash::SimpleBuffer::operator= ( SimpleBuffer &&  )

default

Move assignment is okay.

reserve()

void gnash::SimpleBuffer::reserve ( size_t  newCapacity )

inline

Ensure at least 'newCapacity' bytes are allocated for this buffer.

Referenced by resize().

resize()

void gnash::SimpleBuffer::resize ( size_t  newSize )

inline

Resize the buffer.

References reserve().
