DetectFileType()

virtual string FileLoaderImpl::DetectFileType ( unsigned char *  buf, size_t  buflen, float &  matchness  ) const

pure virtual

Attempt to detect file type.

Parameters

buf	A buffer containing the header of the file.
buflen	The length of the buffer.
matchness	Set to a value between 0.0 and 1.0, indicating the match certainty.

Returns

A file type description, if there was a match; otherwise an empty string.

Implemented in FileLoader_aout, FileLoader_bout, FileLoader_ELF, and FileLoader_raw.

LoadIntoComponent()

virtual bool FileLoaderImpl::LoadIntoComponent ( refcount_ptr< Component >  component, ostream &  messages  ) const

pure virtual

Loads the file into a Component.

Parameters

component	The AddressDataBus component to load the file into. (This is usually a CPUComponent.)
messages	An output stream where debug messages can be put.

Returns

True if loading succeeded, false otherwise.

Implemented in FileLoader_aout, FileLoader_bout, FileLoader_ELF, and FileLoader_raw.
