示例1: newField

import org.apache.lucene.document.FieldType; //导入方法依赖的package包/类
public synchronized static Field newField(Random random, String name, String value, FieldType type) {

    // Defeat any consumers that illegally rely on intern'd
    // strings (we removed this from Lucene a while back):
    name = new String(name);

    FieldType prevType = fieldToType.get(name);

    if (usually(random) || !type.indexed() || prevType != null) {
      // most of the time, don't modify the params
      if (prevType == null) {
        fieldToType.put(name, new FieldType(type));
      } else {
        type = mergeTermVectorOptions(type, prevType);
      }

      return new Field(name, value, type);
    }

    // TODO: once all core & test codecs can index
    // offsets, sometimes randomly turn on offsets if we are
    // already indexing positions...

    FieldType newType = new FieldType(type);
    if (!newType.stored() && random.nextBoolean()) {
      newType.setStored(true); // randomly store it
    }

    // Randomly turn on term vector options, but always do
    // so consistently for the same field name:
    if (!newType.storeTermVectors() && random.nextBoolean()) {
      newType.setStoreTermVectors(true);
      if (!newType.storeTermVectorPositions()) {
        newType.setStoreTermVectorPositions(random.nextBoolean());
        
        if (newType.storeTermVectorPositions()) {
          if (!newType.storeTermVectorPayloads() && !OLD_FORMAT_IMPERSONATION_IS_ACTIVE) {
            newType.setStoreTermVectorPayloads(random.nextBoolean());
          }
        }
      }
      
      if (!newType.storeTermVectorOffsets()) {
        newType.setStoreTermVectorOffsets(random.nextBoolean());
      }

      if (VERBOSE) {
        System.out.println("NOTE: LuceneTestCase: upgrade name=" + name + " type=" + newType);
      }
    }
    newType.freeze();
    fieldToType.put(name, newType);

    // TODO: we need to do this, but smarter, ie, most of
    // the time we set the same value for a given field but
    // sometimes (rarely) we change it up:
    /*
    if (newType.omitNorms()) {
      newType.setOmitNorms(random.nextBoolean());
    }
    */
    
    return new Field(name, value, newType);
  }
