edu.isi.pegasus.planner.invocation.Status

All Implemented Interfaces:

Serializable

public class Status
extends Invocation

This class encapsulates the exit code or reason of termination for a given job. The class itself contains the raw exit code. It also aggregates an instance of the JobStatus interface, which describes more clearly failure, regular execution, signal and suspension.

Field Detail

m_status

private int m_status

The raw exit code, unparsed and unprepared. There are several interpretation of the value. Usually, it is interpreted as unsigned 16 bit value. The high byte contains the exit code. The low byte has the core dump flag as MSB, and the rest denote the signal number. A value of -1 denotes a failure from the grid launcher before starting the job.

m_jobStatus

private JobStatus m_jobStatus

This member variable contains the real status of the job.

Constructor Detail

Status

public Status()

Default c'tor: Construct a hollow shell and allow further information to be added later.

Status

public Status(int raw)

Constructs a layer with the raw exit code.

Parameters:

raw - is the raw exit code to store.

Status

public Status(int raw,
      JobStatus status)

Constructs the complete class with raw exit code and a status child describing the exit code.

Parameters:

raw - is the raw exit status

status - is the description of the kind of exit.

Method Detail

getStatus

public int getStatus()

Accessor

See Also:

setStatus(int)

setStatus

public void setStatus(int status)

Accessor.

Parameters:

status -

See Also:

getStatus()

getJobStatus

public JobStatus getJobStatus()

Accessor

See Also:

setJobStatus( JobStatus )

setJobStatus

public void setJobStatus(JobStatus jobStatus)

Accessor.

Parameters:

jobStatus - is an instance of the class describing the real reason for program termination on the remote end.

getJobStatus()

toString

public void toString(Writer stream)
              throws IOException

Converts the active state into something meant for human consumption. The method will be called when recursively traversing the instance tree.

Specified by:

toString in class org.griphyn.vdl.Chimera

Parameters:

stream - is a stream opened and ready for writing. This can also be a string stream for efficient output.

Throws:

IOException - if something fishy happens to the stream.

toXML

public void toXML(Writer stream,
         String indent,
         String namespace)
           throws IOException

Dump the state of the current element as XML output. This function traverses all sibling classes as necessary, and converts the data into pretty-printed XML output. The stream interface should be able to handle large output efficiently.

Specified by:

toXML in class org.griphyn.vdl.Chimera

Parameters:

stream - is a stream opened and ready for writing. This can also be a string stream for efficient output.

indent - is a String of spaces used for pretty printing. The initial amount of spaces should be an empty string. The parameter is used internally for the recursive traversal. If a null value is specified, no indentation nor linefeeds will be generated.

namespace - is the XML schema namespace prefix. If neither empty nor null, each element will be prefixed with this prefix, and the root element will map the XML namespace.

Throws:

IOException - if something fishy happens to the stream.
