Class SlidingRingWindow<T>

java.lang.Object

com.aizuda.snailjob.client.common.window.SlidingRingWindow<T>

Type Parameters:

T - the type of elements maintained in the window

public class SlidingRingWindow<T>
extends Object

A sliding window implementation that maintains data in a ring buffer structure. The window slides based on either time duration or threshold count, whichever comes first.

Key features:

• Thread-safe implementation using atomic operations
• Supports both time-based and count-based window sliding
• Uses a ring buffer to efficiently manage window segments
• Allows multiple listeners to be notified when window data is emitted

Method Details

shutdown

public void shutdown()

add

public void add(T data)
