Admin (GigaSpaces XAP 14.2.0 API)

All Superinterfaces:

DumpProvider, StatisticsMonitor

All Known Subinterfaces:

InternalAdmin

All Known Implementing Classes:

DefaultAdmin
```
public interface Admin
extends StatisticsMonitor, DumpProvider
```
The main interface for accessing Admin API. Created using the AdminFactory class.
Provides access to the main elements in the Admin API and in GigaSpaces such as the GridServiceAgents, LookupServices, GridServiceManagers, GridServiceContainers, ProcessingUnits, and Spaces.
Also allows to change monitoring (not statistics) interval (works in a polling fashion) of state changing elements such as the processing unit, the Grid Service Agent, and the Space.
Implements the StatisticsMonitor interface, allowing in one single call (StatisticsMonitor.startStatisticsMonitor()) to start statistics monitors on all the elements it manages (such as the Spaces, and VirtualMachines.
Provides one stop shop for registering all event listeners that extend AdminEventListener using the addEventListener(AdminEventListener) and their removal removeEventListener(AdminEventListener). The actual event listener interfaces will be automatically detected and added to the correct component.

- Method Detail
  - getGroups

void setProcessingUnitMonitorInterval(long interval,
                                      TimeUnit timeUnit)
```
    Sets the processing unit monitor (not statistics) interval. The monitor basically checks the status of each processing unit (ProcessingUnit.getStatus() among other things.
    Defaults to 1 second.
    
    Parameters:
    
    interval - The interval to use.
    
    timeUnit - The time unit the interval is at.
  - setAgentProcessessMonitorInterval
```
void setAgentProcessessMonitorInterval(long interval,
                                       TimeUnit timeUnit)
```
    Sets the Grid Service Agent processes monitor (not statistics) interval. The monitor basically updates the list of processes the agent manages (GridServiceAgent.getProcessesDetails().
    Defaults to 5 seconds.
    
    Parameters:
    
    interval - The interval to use.
    
    timeUnit - The time unit the interval is at.
  - setSpaceMonitorInterval
```
void setSpaceMonitorInterval(long interval,
                             TimeUnit timeUnit)
```
    Sets the Space monitor (not statistics) interval. The monitor checks each space instance and updates its different status (such as the replication status).
    Defaults to 1 second.
    
    Parameters:
    
    interval - The interval to use.
    
    timeUnit - The time unit the interval is at.
  - setSchedulerCorePoolSize
```
void setSchedulerCorePoolSize(int coreThreads)
```
    The Admin API uses a shared scheduler thread pool to perform *all* scheduled operations (monitoring, statistics monitoring). The number of threads used can be set here.

    Parameters:
    
    coreThreads - The number of threads the shared scheduler thread pool will use,
