Uses of InterfaceStability.Evolving in org.apache.pig

Classes in org.apache.pig with annotations of type InterfaceStability.Evolving

Modifier and Type	Interface and Description
interface	CollectableLoadFunc This interface implemented by a LoadFunc implementations indicates to Pig that it has the capability to load data such that all instances of a key will occur in same split.
interface	ExecType The type of query execution.
class	Expression A class to communicate Filter expressions to LoadFuncs.
class	FileInputLoadFunc This class provides an implementation of OrderedLoadFunc interface which can be optionally re-used by LoadFuncs that use FileInputFormat, by having this as a super class
class	FileSplitComparable This class represents a relative position in a file.
interface	IndexableLoadFunc This class is intended for use by LoadFunc implementations which have an internal index for sorted data and can use the index to support merge join in Pig.
interface	LoadCaster An interface that provides cast implementations for load functions.
interface	LoadMetadata This interface defines how to retrieve metadata related to data to be loaded.
interface	LoadPredicatePushdown This interface defines how a loader can support predicate pushdown.
interface	LoadPushDown This interface defines how to communicate to Pig what functionality can be pushed into the loader.
static class	LoadPushDown.RequiredField Describes a field that is required to execute a scripts.
static class	LoadPushDown.RequiredFieldList List of fields that Pig knows to be required to executed a script.
static class	LoadPushDown.RequiredFieldResponse Indicates whether the loader will return the requested fields or all fields.
interface	LoadStoreCaster This is just a union interface of LoadCaster and StoreCaster, made available for simplicity.
interface	OrderedLoadFunc Implementing this interface indicates to Pig that a given loader can be used for MergeJoin.
class	PigRunner A utility to help run PIG scripts within a Java program.
interface	StoreCaster An interface that provides methods for converting Pig internal types to byte[].
interface	StoreMetadata This interface defines how to write metadata related to data to be stored.
interface	StoreResources This interface allow StoreFunc to specify resources needed in distributed cache.
