NAME

       globus_gram_job_manager_script_interface - Job Manager Scheduler Interface The GRAM Job Manager
       interfaces with the job filesystems and scheduler through scheduler-specific Perl modules.

       GRAM provides several Perl modules which can be used to implement scheduler-specific interfaces to the
       GRAM Job Manager. These are:

       Globus::GRAM::Error
           This module implements the GRAM error results as objects. Methods in this module will construct a
           GRAM error with the value matching the values in the GRAM Protocol library. A scheduler-specific
           JobManager module may return one of these objects from its methods to indicate errors to the Job
           Manager program.

       Globus::GRAM::JobState
           This module defines the GRAM job state constants. A scheduler-specific JobManager module returns one
           of these values from its methods to indicate the managed job's current state.

       Globus::GRAM::JobSignal
           This module defines the GRAM job signal constant values. The Job Manager uses these values to
           communicate which signal is being invoked in the manager's signal method.

       Globus::GRAM::JobManager
           This module defines the actual implementatoin of the Job Manager scheduler interface. One writing a
           scheduler-specific GRAM interface will create a subclass of this object which overrides the default
           implementation's methods.

       Globus::GRAM::JobDescription
           This module mimics the RSL job description using perl syntax. The job manager passes an object of
           this type to the JobManager modules's constructor. The job manager stores RSL and some configuration
           values in that JobDescription object. The manager accesses values stored in the JobDescription by
           invoking methods containing the RSL attribute's name (example: $description->gram_my_job()). Method
           names are handled as if they were based on the canonical RSL representation of the attribute name.
           For example, the gram_my_job may be equivalently referred to as GramMyJob, grammyjob, or GRAM_My_Job.
