org.eclipse.rse.services.clientserver.processes
Class HostProcessFilterImpl

java.lang.Object
  extended by 
org.eclipse.rse.services.clientserver.processes.HostProcessFilterImpl
All Implemented Interfaces:
Cloneable, IHostProcessFilter

public class HostProcessFilterImpl
extends Object
implements IHostProcessFilter, Cloneable

A class representing a remote process filter string. This is a name pattern for returning lists of remote processes when used as input to the UniversalProcessMiner class. Valid generic names are names with one or two asterisks anywhere in the name, as in: ABC* or *ABC or A*C *ABC* or *A*C or A*C* To get the actual filter string back from objects of this class, just call toString().

Clients may instantiate or subclass this class. When subclassing, clients need to ensure that the subclass is always capable of performing a deep clone operation with the clone() method, so if they add fields of complex type, these need to be dealt with by overriding clone().

allows

public boolean allows(

Description copied from interface: IHostProcessFilter
Returns whether this filter allows a process with the status line status to pass through. The status line contains some of the contents of the status file contained in the processes numbered directory in the /proc filesystem. For example, the status line of process 12345 is the contents of the file /proc/12345/stat. The status line must be structured as follows: "pid|name|status|tgid|ppid|tracerpid|uid|username|gid|vmSize|vmRSS"

Specified by:
allows in interface IHostProcessFilter

Description copied from interface: IHostProcessFilter
Check whether this filter requires that the given state is set.

Specified by:
getSpecificState in interface IHostProcessFilter
Parameters:
stateCode - state code to check. One of the String constants in ISystemProcessRemoteConstants.ALL_STATES_STR.

setSpecificState

public void setSpecificState(
String stateCode)
Description copied from interface: IHostProcessFilter
Change this filter such that it requires the given state to be set.

Specified by:
setSpecificState in interface IHostProcessFilter
Parameters:
stateCode - state code to check. One of the String constants in ISystemProcessRemoteConstants.ALL_STATES_STR.

satisfiesState

public boolean satisfiesState(

Check whether a given process state String matches this filter.

Specified by:
satisfiesState in interface IHostProcessFilter
Parameters:
stateString - A state String, holding a list of state constants from ISystemProcessRemoteConstants.ALL_STATES_STR, separated by comma (",").

clone

public 
Object clone()
Return an identical (deep) copy of this filter. Subclasses must ensure that such a deep copy operation is always possible, so their state must always be cloneable. Which should always be possible to achieve, since this Object also needs to be serializable.

Overrides:
clone in class Object
