Method Detail

size

public Integer size()

Description copied from interface: MessageSequence

The number of members of the sequence. If this is unknown, return UNKNOWN_SIZE.

Specified by:

size in interface MessageSequence<Collection<Q>>

Returns:

The estimated size of the sequence, or MessageSequence.UNKNOWN_SIZE, if it is unknown

hasNext

public boolean hasNext()

Description copied from interface: MessageSequence

Whether this sequence has more elements.

Specified by:

hasNext in interface Iterator<Collection<Q>>

Specified by:

hasNext in interface MessageSequence<Collection<Q>>

Iterator.hasNext()

next

public Collection<Q> next()

Description copied from interface: MessageSequence

The next element of the sequence. At any moment, if MessageSequence.size() is not equal to MessageSequence.UNKNOWN_SIZE, this means that this method may be invoked approximately up to MessageSequence.size() times.

Specified by:

next in interface Iterator<Collection<Q>>

Specified by:

next in interface MessageSequence<Collection<Q>>

isEmpty

public boolean isEmpty()

Description copied from interface: MessageSequence

If the sequence is empty

Specified by:

isEmpty in interface MessageSequence<Collection<Q>>

Returns:

!hasNext()

remove

public void remove()

Description copied from interface: MessageSequence

Unsupported operation. MessageSequence do not allow removal of elements.

Specified by:

remove in interface Iterator<Collection<Q>>
