public BlockingQueue()

Method Detail

size

public int size()

Description copied from interface: Queue

Returns the number of elements in this list. If this list contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

Specified by:

size in interface Queue

Returns:

the number of elements in this list.

Queue.size()

isEmpty

public boolean isEmpty()

Description copied from interface: Queue

Returns true if this list contains no elements.

Specified by:

Returns:

true if this list contains no elements.

See Also:

Queue.isEmpty()

add

public boolean add(java.lang.Object o)

Description copied from interface: Queue

Appends the specified element to the end of this list (optional operation).

Lists that support this operation may place limitations on what elements may be added to this list. In particular, some lists will refuse to add null elements, and others will impose restrictions on the type of elements that may be added. List classes should clearly specify in their documentation any restrictions on what elements may be added.

Specified by:

add in interface Queue

Returns:

true (as per the general contract of the Collection.add method).

Queue.add(java.lang.Object)

get

addAll

public boolean addAll(java.util.Collection coll)

Description copied from interface: Queue

Appends all of the elements in the specified collection to the end of this list, in the order that they are returned by the specified collection's iterator (optional operation). The behavior of this operation is unspecified if the specified collection is modified while the operation is in progress. (Note that this will occur if the specified collection is this list, and it's nonempty.)

Specified by:

addAll in interface Queue

Returns:

true if this list changed as a result of the call.
