Method Detail

map

public <P> ComputeTSet<P,java.util.Iterator<T>> map(MapFunc<P,T> mapFn)

Description copied from interface: TLink

Performs elementwise map operation based on the MapFunc provided

Type Parameters:

P - output type

Parameters:

mapFn - map function T0 to O

Returns:

Compute tset

flatmap

public <P> ComputeTSet<P,java.util.Iterator<T>> flatmap(FlatMapFunc<P,T> mapFn)

Description copied from interface: TLink

Performs flat map operation based on the FlatMapFunc provided

Type Parameters:

P - map function to T0 to multiple elements of <O>

Parameters:

mapFn - map function which can produce multiple elements for a single <T0> element

Returns:

Compute TSet

mapToTuple

public <K,V> KeyedTSet<K,V> mapToTuple(MapFunc<Tuple<K,V>,T> mapToTupFn)

Description copied from interface: TLink

Maps the data passed through the TLink to Tuple based on a MapFunc and thereby creating a TupleTSet

Type Parameters:

K - key type

V - value type

Parameters:

mapToTupFn - MapFunc to generate a Tuple

Returns:

Keyed TSet

lazyForEach

public ComputeTSet<java.lang.Object,java.util.Iterator<T>> lazyForEach(ApplyFunc<T> applyFunction)

forEach

public void forEach(ApplyFunc<T> applyFunction)

Description copied from interface: TLink

Applies a function elementwise. Similar to compute, but the ApplyFunc does not return anything.

Parameters:

applyFunction - apply function
