std::tuple< bool, Block > ndn::Block::fromBuffer ( ConstBufferPtr  buffer, size_t  offset  )

static

Try to construct block from Buffer.

Parameters

buffer

the buffer to construct block from

Note

buffer is passed by value because the constructed block takes shared ownership of the buffer

Parameters

offset

offset from beginning of buffer to construct Block from

This method does not throw upon decoding error. This method does not copy the bytes.

Returns

true and the Block, if Block is successfully created; otherwise false
