Method Details

getCore

public ICore getCore()

Description copied from interface: IAddressSpace

The core file from which this address space has been created from

Returns:

the core file or null if this address space is not backed by an underlying core file

getCommandLine

public String getCommandLine()
                      throws CorruptDataException,
DataUnavailableException

Returns:

Process command line or null if the data is unavailable

Throws:

CorruptDataException

DataUnavailableException

getEnvironmentVariables

public Properties getEnvironmentVariables()
                                   throws DataUnavailableException,
CorruptDataException

This method tries to get environment variables by iterating through modules. It returns the one with environment variable "OPENJ9_JAVA_COMMAND_LINE" or "IBM_JAVA_COMMAND_LINE". If no module has either, then it returns the last one.

Returns:

Properties instance of environment variables

Throws:

DataUnavailableException

CorruptDataException

getExecutable

public IModule getExecutable()
                      throws CorruptDataException

Throws:

CorruptDataException

public long getProcessId()
                  throws CorruptDataException

Throws:

CorruptDataException

getThreads

public List<IOSThread> getThreads()
                           throws CorruptDataException

Throws:

CorruptDataException

getPlatform

public Platform getPlatform()

getSignalNumber

public int getSignalNumber()
                    throws DataUnavailableException

Throws:

DataUnavailableException

isFailingProcess
