Detailed Description

BinaryStreamRef is to BinaryStream what ArrayRef is to an Array.

It provides copy-semantics and read only access to a "window" of the underlying BinaryStream. Note that BinaryStreamRef is not a BinaryStream. That is to say, it does not inherit and override the methods of BinaryStream. In general, you should not pass around pointers or references to BinaryStreams and use inheritance to achieve polymorphism. Instead, you should pass around BinaryStreamRefs by value and achieve polymorphism that way.

◆ readBytes()

Error BinaryStreamRef::readBytes	(	uint64_t	Offset,
		uint64_t	Size,
		ArrayRef< uint8_t > &	Buffer ) const

Given an Offset into this StreamRef and a Size, return a reference to a buffer owned by the stream.

Returns: a success error code if the entire range of data is within the bounds of this BinaryStreamRef's view and the implementation could read the data, and an appropriate error code otherwise.
