WritableMemory.clearBits介绍

[英]Clears the bits defined by the bitMask
[中]清除位掩码定义的位

代码示例

代码示例来源：origin: DataSketches/sketches-core

@Override
protected void setNotEmpty() {
 if (isEmpty_) {
  isEmpty_ = false;
  mem_.clearBits(FLAGS_BYTE, (byte) (1 << Flags.IS_EMPTY.ordinal()));
 }
}

代码示例来源：origin: DataSketches/sketches-core

@Test(expectedExceptions = SketchesArgumentException.class)
public void compactNotSupported() {
 ArrayOfDoublesSerDe serDe = new ArrayOfDoublesSerDe();
 ItemsSketch<Double> sketch = ItemsSketch.getInstance(Comparator.naturalOrder());
 byte[] byteArr = sketch.toByteArray(serDe);
 WritableMemory mem = WritableMemory.wrap(byteArr);
 mem.clearBits(PreambleUtil.FLAGS_BYTE, (byte) PreambleUtil.COMPACT_FLAG_MASK);
 println(PreambleUtil.toString(mem, false));
 ItemsSketch.getInstance(mem, Comparator.naturalOrder(), serDe);
}

代码示例来源：origin: DataSketches/sketches-core

@Test(expectedExceptions = SketchesArgumentException.class)
public void checkHeapifyNotCompactExcep() {
 int k = 512;
 UpdateSketch sketch1 = UpdateSketch.builder().setFamily(QUICKSELECT).setNominalEntries(k).build();
 int bytes = Sketch.getMaxCompactSketchBytes(0);
 byte[] byteArray = new byte[bytes];
 WritableMemory mem = WritableMemory.wrap(byteArray);
 sketch1.compact(false, mem);
 //corrupt:
 mem.clearBits(FLAGS_BYTE, (byte) COMPACT_FLAG_MASK);
 Sketch.heapify(mem);
}

 WritableMemory mem = WritableMemory.wrap(byteArray);
 sketch1.compact(false, mem);
 //corrupt:
 mem.clearBits(FLAGS_BYTE, (byte) COMPACT_FLAG_MASK);
