Detailed Description

An implementation of BinaryStream which holds its entire data set in a single contiguous buffer.

As with BinaryByteStream, the mutable version also guarantees that no read operation will ever incur a copy, and similarly it does not own the underlying buffer.

getLength()

uint32_t llvm::MutableBinaryByteStream::getLength ( )

inlineoverridevirtual

Return the number of bytes of data in this stream.

Implements llvm::BinaryStream.

readBytes()

Error llvm::MutableBinaryByteStream::readBytes ( uint32_t  Offset, uint32_t  Size, ArrayRef< uint8_t > &  Buffer  )

inlineoverridevirtual

Given an offset into the stream and a number of bytes, attempt to read the bytes and set the output ArrayRef to point to data owned by the stream.

Implements llvm::BinaryStream.

Definition at line 101 of file BinaryByteStream.h.

readLongestContiguousChunk()

Error llvm::MutableBinaryByteStream::readLongestContiguousChunk ( uint32_t  Offset, ArrayRef< uint8_t > &  Buffer  )

inlineoverridevirtual

Given an offset into the stream, read as much as possible without copying any data.

Implements llvm::BinaryStream.

Definition at line 106 of file BinaryByteStream.h.

writeBytes()

Error llvm::MutableBinaryByteStream::writeBytes ( uint32_t  Offset, ArrayRef< uint8_t >  Data  )

inlineoverridevirtual

Attempt to write the given bytes into the stream at the desired offset.

This will always necessitate a copy. Cannot shrink or grow the stream, only writes into existing allocated space.

Implements llvm::WritableBinaryStream.
