示例1: getBuffer
import java.util.TreeMap; //导入方法依赖的package包/类
@Override
public synchronized ByteBuffer getBuffer(boolean direct, int length) {
TreeMap<Key, ByteBuffer> tree = getBufferTree(direct);
Map.Entry<Key, ByteBuffer> entry =
tree.ceilingEntry(new Key(length, 0));
if (entry == null) {
return direct ? ByteBuffer.allocateDirect(length) :
ByteBuffer.allocate(length);
}
tree.remove(entry.getKey());
return entry.getValue();
}
示例2: indexIn
import java.util.TreeMap; //导入方法依赖的package包/类
