Description
Interface Summary | |
---|---|
Algebraic | An interface to declare that an EvalFunc's calculation can be decomposed into intitial, intermediate, and final steps. |
LoadFunc | This interface is used to implement functions to parse records from a dataset. |
ReversibleLoadStoreFunc | This interface is used to implement classes that can perform both Load and Store functionalities in a symmetric fashion (thus reversible). |
SamplableLoader | Implementing this interface indicates to Pig that a given loader can be used by a sampling loader. |
Slice | A grouping of data on that can be processed individually by Pig. |
Slicer | Produces independent slices of data from a given location to be processed in parallel by Pig. |
StoreFunc | This interface is used to implement functions to write records from a dataset. |
Class Summary | |
---|---|
ComparisonFunc | |
EvalFunc<T> | The class is used to implement functions to be applied to a dataset. |
FilterFunc | |
FuncSpec | Class to represent a UDF specification - essentially encapsulates the class name and the arguments to the constructor |
Main | |
PigServer | This class is the program's connection to Pig. |
StandAloneParser | |
StoreConfig | A Class which will encapsulate metadata information that a OutputFormat (or possibly StoreFunc) may want to know about the data that needs to be stored. |
Enum Summary | |
---|---|
ExecType | The type of query execution |
PigWarning | An enum to enumerate the warning types in Pig |
Exception Summary | |
---|---|
PigException | All exceptions in Pig are encapsulated in the PigException
class. |
Public interfaces and classes for Pig.
PigServer
is the interface to Pig for use by other java
programs. Other interfaces and classes in this package are for use by users
when implementing user defined functions.
