Constructor Detail

BufferManager.CloseableDistinctBuffer

protected BufferManager.CloseableDistinctBuffer(String name,
                                     boolean onHeap,
                                     Set<T> buffer)

Method Detail

isEmpty

public boolean isEmpty()

Description copied from interface: BufferManager.Buffer

Determine if this buffer is empty. This may be more efficient than BufferManager.Buffer.size().

Specified by:

isEmpty in interface BufferManager.Buffer

Returns:

true if the buffer is empty, or false otherwise

size

public long size()

Description copied from interface: BufferManager.Buffer

Get the size of the buffer. This might be more expensive if the buffer is not created with the flag to keep the size.

Specified by:

size in interface BufferManager.Buffer

Returns:

the size of the buffer.

contains

public boolean contains(T value)

Description copied from interface: BufferManager.Predicate

Determine whether the buffer has seen this value.

Specified by:

contains in interface BufferManager.Predicate<T>

Parameters:

value - the value

Returns:

true if the buffer already has seen that value, or false otherwise

iterator

public Iterator<T> iterator()

Description copied from interface: BufferManager.DistinctBuffer

Get an iterator over all of the records.

Specified by:

iterator in interface Iterable<T>

Specified by:

iterator in interface BufferManager.DistinctBuffer<T>

Returns:

the iterator; never null

toString

public String toString()

Overrides:

toString in class Object
