Detailed Description

ObjectBuffer - This class acts as a container for the memory buffer used during generation and loading of executable objects using MCJIT and RuntimeDyld. The underlying memory for the object will be owned by the ObjectBuffer instance throughout its lifetime. The getMemBuffer() method provides a way to create a MemoryBuffer wrapper object instance to be owned by other classes (such as ObjectFile) as needed, but the MemoryBuffer instance returned does not own the actual memory it points to.

MemoryBuffer* llvm::ObjectBuffer::getMemBuffer ( ) const

inline

getMemBuffer - Like MemoryBuffer::getMemBuffer() this function returns a pointer to an object that is owned by the caller. However, the caller does not take ownership of the underlying memory.
