我试图插入这个简单的scala代码,但我遇到了一些麻烦.

package indicators

class DoubleRingBuffer(val capacity:Int=1000) {
  var elements = new Array[Double](capacity);
  private var head=capacity-1
  private var max=0

  def size ():Int = {
    return max+1
  }

  def add(obj:Double):Double = {
    head-=1
    if (head<0) head=capacity-1
    return set(max+1,obj)
  }

  def set(i:Int,obj:Double):Double = {
    System.out.println("HI")
    if (i>=capacity || i<0)
      throw new IndexOutOfBoundsException(i+" out of bounds")
    if (i>=max) max=i
    var index = (head+i)%capacity
    var prev = elements(index)
    elements(index)=obj
    return prev
  }

  def get(i:Int=0):Double = {
    System.out.println("size is "+size())
    if (i>=size() || i<0)
      throw new …

每次我在emacs中突出显示某些内容时,都会复制它.有没有办法禁用这种烦人的行为？我在ubuntu上.
