Document

Creates and returns a new builder, configured to build MinMaxPriorityQueue instances sized appropriately to hold expectedSize elements.

Usage

From source file:org.apache.hadoop.hbase.io.hfile.CachedBlockQueue.java

/**
 * @param maxSize the target size of elements in the queue
 * @param blockSize expected average size of blocks
 *//*from   w w  w .j  ava2 s  .  c om*/
public CachedBlockQueue(long maxSize, long blockSize) {
    int initialSize = (int) (maxSize / blockSize);
    if (initialSize == 0)
        initialSize++;
    queue = MinMaxPriorityQueue.expectedSize(initialSize).create();
    heapSize = 0;
    this.maxSize = maxSize;
}
