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.

    public void testParsingAsGenerateInForeachWithOutBlock() throws Throwable {
        PigServer server = new PigServer(ExecType.MAPREDUCE, cluster.getProperties());
        PigContext context = server.getPigContext();
        
        String strCmd = "a = load 'foo' as (foo, fast, regenerate); "
                + "b = group a by foo; c = foreach b generate "
                + "{(1, '1', 0.4f),(2, '2', 0.45)} "
