Modifier and Type	Method	Description
`static OverflowStrategy`	`backpressure()`	If the buffer is full when a new element is available this strategy backpressures the upstream publisher until space becomes available in the buffer.
`static OverflowStrategy`	`dropBuffer()`	If the buffer is full when a new element arrives, drops all the buffered elements to make space for the new element.
`static OverflowStrategy`	`dropHead()`
`static OverflowStrategy`	`dropNew()`	If the buffer is full when a new element arrives, drops the new element.
`static OverflowStrategy`	`dropTail()`	If the buffer is full when a new element arrives, drops the youngest element from the buffer to make space for the new element.
`static OverflowStrategy`	`fail()`	If the buffer is full when a new element is available this strategy completes the stream with failure.
