processDump

public ICore processDump(String path)
                  throws InvalidDumpFormatException,
IOException

Description copied from interface: ICoreFileReader

Called when a core reader should process the dump. This allows lazy initialisation of the readers especially when they are not subsequently used.

Specified by:

processDump in interface ICoreFileReader

Throws:

InvalidDumpFormatException

IOException

public ICoreFileReader.DumpTestResult testDump(String path)
                                        throws IOException

Description copied from interface: ICoreFileReader

Tests the dump described by the path for compatibility with this CoreFileReader.

Specified by:

testDump in interface ICoreFileReader

Parameters:

path - Path to dump file.

Throws:

IOException - If there was an IO problem reading the file (disk full etc.). Note that FileNotFound should be handled with DumpTestResult.
