Detailed Description

Elementary part of a DataSource for a simple block of memory.

Class possibly referencing a buffer of bytes, specified in 4 possible different ways:

• a raw pointer + size.
• a trivially copyable object of type T.
• a vector<T> of trivially copyable objects of type T.
• an empty buffer (default constructor).

This class is meant to simplify the manipulation of a buffer of bytes, for use by DataSource. Only the constructors and assignment operators are meant to be used by code outside of DataSource.

Member Function Documentation

fillAndAdvanceBuffer()

void vrs::DataSourceChunk::fillAndAdvanceBuffer ( uint8_t *&  buffer ) const

virtual

Copy the data (if any), and update the provided buffer pointer accordingly. The number of bytes copied must be the exact size specified in the constructor.

Reimplemented in vrs::NonContiguousChunk.
