示例1: readFromStream
import io.netty.buffer.DrillBuf; //导入方法依赖的package包/类
/**
* Reads from an InputStream and parses a RecordBatchDef. From this, we construct a SelectionVector2 if it exits
* and construct the vectors and add them to a vector container
* @param input the InputStream to read from
* @throws IOException
*/
@Override
public void readFromStream(InputStream input) throws IOException {
final VectorContainer container = new VectorContainer();
final UserBitShared.RecordBatchDef batchDef = UserBitShared.RecordBatchDef.parseDelimitedFrom(input);
recordCount = batchDef.getRecordCount();
if (batchDef.hasCarriesTwoByteSelectionVector() && batchDef.getCarriesTwoByteSelectionVector()) {
if (sv2 == null) {
sv2 = new SelectionVector2(allocator);
}
sv2.allocateNew(recordCount * SelectionVector2.RECORD_SIZE);
sv2.getBuffer().setBytes(0, input, recordCount * SelectionVector2.RECORD_SIZE);
svMode = BatchSchema.SelectionVectorMode.TWO_BYTE;
}
final List<ValueVector> vectorList = Lists.newArrayList();
final List<SerializedField> fieldList = batchDef.getFieldList();
for (SerializedField metaData : fieldList) {
final int dataLength = metaData.getBufferLength();
final MaterializedField field = MaterializedField.create(metaData);
final DrillBuf buf = allocator.buffer(dataLength);
final ValueVector vector;
try {
buf.writeBytes(input, dataLength);
vector = TypeHelper.getNewVector(field, allocator);
vector.load(metaData, buf);
} finally {
buf.release();
}
vectorList.add(vector);
}
container.addCollection(vectorList);

示例2: decompress
import io.netty.buffer.DrillBuf; //导入方法依赖的package包/类
@Override
public void decompress(DrillBuf input, int compressedSize, DrillBuf output, int uncompressedSize)
throws IOException {
decompressor.reset();
byte[] inputBytes = new byte[input.capacity()];
input.getBytes(0, inputBytes);
decompressor.setInput(inputBytes, 0, inputBytes.length);

output.clear();
output.writeBytes(outputBytes);
