Document

If the buffer is full, the least recently added element is discarded so that a new element can be inserted.

Usage

From source file:ch.algotrader.esper.aggregation.GenericTALibFunction.java

@Override
public void enter(Object obj) {

    Object[] params = (Object[]) obj;

    // add all inputs to the correct buffers
    int paramCount = 1;
    for (CircularFifoBuffer<Number> buffer : this.inputParams) {
        Number value = (Number) params[paramCount];
        buffer.add(value);
        paramCount++;//from w  w w .  ja  v  a 2s . c  o m
    }
}
