这份文档介绍如何在geode中增加一个gfsh命令。

1. Adding a new Gfsh command

public class LuceneCreateIndexFunction extends FunctionAdapter implements InternalEntity {

}

/* Only show these commands as available when gfsh is online */

@CliAvailabilityIndicator({LuceneCliStrings.LUCENE_SEARCH_INDEX, LuceneCliStrings.LUCENE_CREATE_INDEX,

 LuceneCliStrings.LUCENE_DESCRIBE_INDEX, LuceneCliStrings.LUCENE_LIST_INDEX})

 public boolean indexCommandsAvailable() {

  return (!CliUtil.isGfshVM() || (getGfsh() != null && getGfsh().isConnectedAndReady()))

 }

1.4  Tests

For each command, need at least dunit test and junit tests.
