Class: Apache::Hadoop::Hbase::Thrift2::TGet

Inherits:

Object

• Object

Includes:

Thrift::Struct, Thrift::Struct_Union

Defined in:

lib/hbase/hbase_types.rb

Overview

The scope can be further narrowed down by specifying a list of columns or column families.

To get everything for a row, instantiate a Get object with just the row to get. To further define the scope of what to get you can add a timestamp or time range with an optional maximum number of versions to return.

If you specify a time range and a timestamp the range is ignored. Timestamps on TColumns are ignored.
