Class JRubyFormat

java.lang.Object

org.apache.hadoop.hbase.util.JRubyFormat

@InterfaceAudience.Private
public final class JRubyFormat
extends Object

Utility class for converting objects to JRuby. It handles null, Boolean, Number, String, byte[], List<Object>, Map<String, Object> structures.

E.g.

 Map<String, Object> map = new LinkedHashMap<>();
 map.put("null", null);
 map.put("boolean", true);
 map.put("number", 1);
 map.put("string", "str");
 map.put("binary", new byte[] { 1, 2, 3 });
 map.put("list", Lists.newArrayList(1, "2", true));
 

Calling print(Object) method will result:

 { null => '', boolean => 'true', number => '1', string => 'str',
   binary => '010203', list => [ '1', '2', 'true' ] }
