readBytes()

Error llvm::AppendingBinaryByteStream::readBytes ( uint64_t Offset, uint64_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 146 of file BinaryByteStream.h.

References llvm::ArrayRef(), llvm::WritableBinaryStream::checkOffsetForWrite(), llvm::Offset, Size, llvm::ArrayRef< T >::size(), llvm::ArrayRef< T >::slice(), and llvm::Error::success().

readLongestContiguousChunk()

Error llvm::AppendingBinaryByteStream::readLongestContiguousChunk ( uint64_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 159 of file BinaryByteStream.h.

References llvm::ArrayRef(), llvm::WritableBinaryStream::checkOffsetForWrite(), llvm::Offset, llvm::ArrayRef< T >::slice(), and llvm::Error::success().

writeBytes()

Error llvm::AppendingBinaryByteStream::writeBytes ( uint64_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.
