Specified by:

shuffled in interface BaseStream<T,A,P,C,PL,OT,IT,S extends com.landawn.abacus.util.stream.StreamBase<T,A,P,C,PL,OT,IT,S>>

Returns:

toImmutableList

public ImmutableList<T> toImmutableList()

Specified by:

toImmutableList in interface BaseStream<T,A,P,C,PL,OT,IT,S extends com.landawn.abacus.util.stream.StreamBase<T,A,P,C,PL,OT,IT,S>>

toImmutableSet

public ImmutableSet<T> toImmutableSet()

Specified by:

toImmutableSet in interface BaseStream<T,A,P,C,PL,OT,IT,S extends com.landawn.abacus.util.stream.StreamBase<T,A,P,C,PL,OT,IT,S>>

println

public void println()

Specified by:

println in interface BaseStream<T,A,P,C,PL,OT,IT,S extends com.landawn.abacus.util.stream.StreamBase<T,A,P,C,PL,OT,IT,S>>

isParallel

public boolean isParallel()

Description copied from interface: BaseStream

Returns whether this stream, if a terminal operation were to be executed, would execute in parallel. Calling this method after invoking an terminal stream operation method may yield unpredictable results.

Specified by:

isParallel in interface BaseStream<T,A,P,C,PL,OT,IT,S extends com.landawn.abacus.util.stream.StreamBase<T,A,P,C,PL,OT,IT,S>>

Returns:

true if this stream would execute in parallel if executed

sequential

public S sequential()

Description copied from interface: BaseStream

Returns an equivalent stream that is sequential. May return itself, either because the stream was already sequential, or because the underlying stream state was modified to be sequential.

Specified by:

sequential in interface BaseStream<T,A,P,C,PL,OT,IT,S extends com.landawn.abacus.util.stream.StreamBase<T,A,P,C,PL,OT,IT,S>>

Returns:

a sequential stream

parallel

public S parallel()

Description copied from interface: BaseStream

Returns an equivalent stream that is parallel. May return itself if the stream was already parallel. Any parallel should be closed by try-catch or call tried before last step.

Specified by:

parallel in interface BaseStream<T,A,P,C,PL,OT,IT,S extends com.landawn.abacus.util.stream.StreamBase<T,A,P,C,PL,OT,IT,S>>

Returns:

a parallel stream

See Also:

BaseStream.parallel(int, Splitor)

parallel

public S parallel(int maxThreadNum)

Description copied from interface: BaseStream

Returns an equivalent stream that is parallel. May return itself if the stream was already parallel with the same maxThreadNum as the specified one.

Specified by:

parallel in interface BaseStream<T,A,P,C,PL,OT,IT,S extends com.landawn.abacus.util.stream.StreamBase<T,A,P,C,PL,OT,IT,S>>

Returns:

See Also:

BaseStream.parallel(int, Splitor)

maxThreadNum

public int maxThreadNum()

Description copied from interface: BaseStream

Return the underlying maxThreadNum if the stream is parallel, otherwise 1 is returned.

Returns:

maxThreadNum

public S maxThreadNum(int maxThreadNum)

Description copied from interface: BaseStream

Returns a parallel stream with the specified maxThreadNum . Or return itself, either because the stream was already parallel with same maxThreadNum, or because it's a sequential stream.
