Examples of org.apache.pig.PigServer.store()

org.apache.pig.PigServer.store()
Executes a Pig Latin script up to and including indicated alias and stores the resulting records into a file. That is, if a user does:
```
 PigServer server = new PigServer(); server.registerQuery("A = load 'foo';"); server.registerQuery("B = filter A by $0 > 0;"); server.registerQuery("C = order B by $1;"); 
```
Then
```
 server.store("B", "bar"); 
```
filtered but unsorted data will be stored to the file bar. If instead a user does
```
 server.store("C", "bar"); 
```
filtered and sorted data will be stored to the file bar. Equivalent to calling {@link #store(String,String,String)} withorg.apache.pig.PigStorage as the store function. @param id The alias to store @param filename The file to which to store to @return {@link ExecJob} containing information about this job @throws IOException
