Overrides:

decorateProgramInfo in class ElfNote

Parameters:

programInfoOptions - Options to add entry to

markupProgram

public void markupProgram(Program program,
 Address address)

Description copied from interface: ElfInfoItem

Markup a program's info and memory with this item.

Specified by:

markupProgram in interface ElfInfoItem

Overrides:
