Interface ProcessList

All Superinterfaces:

AutoCloseable, Closeable, OsidList, OsidList

public interface ProcessList
extends OsidList

Like all OsidLists , ProcessList provides a means for accessing Process elements sequentially either one at a time or many at a time. Examples:

while (pl.hasNext()) {
     Process process = pl.getNextProcess();
}            
  

or

while (pl.hasNext()) {
     Process[] processes = pl.getNextProcesses(pl.available());
}
