Method Details

getAddress

public ImagePointer getAddress()

Description copied from interface: CorruptData

Return an address associated with the corruption. If the corruption is not associated with an address, return null. If the corruption is associated with more than one address, return the one which best identifies the corruption.

Specified by:

getAddress in interface CorruptData

Returns:

the address of the corrupted data.
