Examples of PigServer

org.apache.pig.PigServer
This class is the program's connection to Pig. Typically a program will create a PigServer instance. The programmer then registers queries using registerQuery() and retrieves results using openIterator() or store().
org.apache.pig.pigunit.pig.PigServer
Slightly modified PigServer that accepts a list of Pig aliases to override.
The list is given to the GruntParser.
