Uses of InterfaceAudience.Public in org.apache.pig

Classes in org.apache.pig with annotations of type InterfaceAudience.Public

Modifier and Type	Interface and Description
interface	Accumulator<T> An interface that allows UDFs that take a bag to accumulate tuples in chunks rather than take the whole set at once.
interface	Algebraic An interface to declare that an EvalFunc's calculation can be decomposed into intitial, intermediate, and final steps.
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.
class	ComparisonFunc Deprecated.
class	EvalFunc<T> The class is used to implement functions to be applied to fields in a dataset.
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.
class	FilterFunc
class	FuncSpec Class to represent a UDF specification.
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.
class	IteratingAccumulatorEvalFunc<T> This class provides a much more intuitive way to write Accumulator UDFs. For example, you could express IsEmpty as follows:
class	JVMReuseManager This class is used to manage JVM Reuse in case of execution engines like Tez and Spark.
interface	LoadCaster An interface that provides cast implementations for load functions.
class	LoadFunc A LoadFunc loads data into Pig.
interface	LoadMetadata This interface defines how to retrieve metadata related to data to be loaded.
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	PigConstants
class	PigRunner A utility to help run PIG scripts within a Java program.
class	PigServer A class for Java programs to connect to Pig.
class	PigStreamingBase The interface is used for the custom mapping of - a Tuple to a byte array.
interface	PigToStream Deprecated. Use PigStreamingBase
class	ResourceSchema A represenation of a schema used to communicate with load and store functions.
class	ResourceStatistics An class that represents statistics about data to be loaded or stored.
interface	StoreCaster An interface that provides methods for converting Pig internal types to byte[].
class	StoreFunc StoreFuncs take records from Pig's processing and store them into a data store.
interface	StoreFuncInterface StoreFuncs take records from Pig's processing and store them into a data store.
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.
interface	StreamToPig Deprecated. Use PigStreamingBase
