Member Function Documentation

◆ Find()

void Isis::Blob::Find ( const Pvl & pvl )

protectedinherited

This method searches the given Pvl for the Blob by the Blob's type and name.

If found, the start byte, number of bytes are read from the Pvl. Also, if a keyword label pointer is found, the filename for the detached blob is stored and the pointer is removed from the blob pvl.

Parameters

pvl	The Pvl to be searched
