Method Detail

testDump

ICoreFileReader.DumpTestResult testDump(String path)
                                 throws IOException

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

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.

testDump

ICoreFileReader.DumpTestResult testDump(ImageInputStream in)
                                 throws IOException

Tests the dump represented by the input stream for compatibility with this CoreFileReader.

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.

processDump

ICore processDump(String path)
           throws InvalidDumpFormatException,
                  IOException

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

Throws:

InvalidDumpFormatException

IOException

processDump

ICore processDump(ImageInputStream in)
           throws InvalidDumpFormatException,
                  IOException

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

Throws:

InvalidDumpFormatException

IOException
