----------------------------------
here list the examples in the unit test case:
{code}
+
+ define_test "get should support COLUMNS with value CONVERTER information"
do
+ @test_table.put(1, "x:c", [1024].pack('N'))
+ @test_table.put(1, "x:d", [98].pack('N'))
+ begin
+ res = @test_table._get_internal('1', ['x:c:toInt'],
['x:d:c(org.apache.hadoop.hbase.util.Bytes).toInt'])
+ assert_not_nil(res)
+ assert_kind_of(Hash, res)
+ assert_not_nil(/value=1024/.match(res['x:c']))
+ assert_not_nil(/value=98/.match(res['x:d']))
+ ensure
+ # clean up newly added columns for this test only.
+ @test_table.delete(1, "x:c")
+ @test_table.delete(1, "x:d")
+ end
+ end
+
+ define_test "scan should support COLUMNS with value CONVERTER information"
do
+ @test_table.put(1, "x:c", [1024].pack('N'))
+ @test_table.put(1, "x:d", [98].pack('N'))
+ begin
+ res = @test_table._scan_internal COLUMNS => ['x:c:toInt',
'x:d:c(org.apache.hadoop.hbase.util.Bytes).toInt']
+ assert_not_nil(res)
+ assert_kind_of(Hash, res)
+ assert_not_nil(/value=1024/.match(res['1']['x:c']))
+ assert_not_nil(/value=98/.match(res['1']['x:d']))
+ ensure
+ # clean up newly added columns for this test only.
+ @test_table.delete(1, "x:c")
+ @test_table.delete(1, "x:d")
+ end
+end
