public interface Puttable

This interface exists to enable stricter type checking for channels. A method argument or instance variable in a producer object can be declared as only a Puttable rather than a Channel, in which case a Java compiler will disallow take operations.

Full method descriptions appear in the Channel interface.

方法摘要

boolean	offer(Object item, long msecs) Place item in channel only if it can be accepted within msecs milliseconds.
void	put(Object item) Place item in the channel, possibly waiting indefinitely until it can be accepted.

方法详细信息

put

void put(Object item)
         throws InterruptedException

Place item in the channel, possibly waiting indefinitely until it can be accepted. Channels implementing the BoundedChannel subinterface are generally guaranteed to block on puts upon reaching capacity, but other implementations may or may not block.

参数：

item - the element to be inserted. Should be non-null.

抛出：

InterruptedException - if the current thread has been interrupted at a point at which interruption is detected, in which case the element is guaranteed not to be inserted. Otherwise, on normal return, the element is guaranteed to have been inserted.

offer

boolean offer(Object item,
              long msecs)
              throws InterruptedException

Place item in channel only if it can be accepted within msecs milliseconds. The time bound is interpreted in a coarse-grained, best-effort fashion.

参数：

item - the element to be inserted. Should be non-null.

msecs - the number of milliseconds to wait. If less than or equal to zero, the method does not perform any timed waits, but might still require access to a synchronization lock, which can impose unbounded delay if there is a lot of contention for the channel.

返回：

true if accepted, else false

抛出：

InterruptedException - if the current thread has been interrupted at a point at which interruption is detected, in which case the element is guaranteed not to be inserted (i.e., is equivalent to a false return).
