Instance Attribute Details

#append_value ⇒ ::String

Returns Rule specifying that append_value be appended to the existing value. If the targeted cell is unset, it will be treated as containing the empty string.

Returns:

• (::String) —

  Rule specifying that append_value be appended to the existing value. If the targeted cell is unset, it will be treated as containing the empty string.

#column_qualifier ⇒ ::String

Returns The qualifier of the column to which the read/modify/write should be applied. Can be any byte string, including the empty string.

Returns:

• (::String) —

  The qualifier of the column to which the read/modify/write should be applied. Can be any byte string, including the empty string.

#family_name ⇒ ::String

Returns The name of the family to which the read/modify/write should be applied. Must match [-_.a-zA-Z0-9]+.

Returns:

• (::String) —

  The name of the family to which the read/modify/write should be applied. Must match [-_.a-zA-Z0-9]+

#increment_amount ⇒ ::Integer

Returns Rule specifying that increment_amount be added to the existing value. If the targeted cell is unset, it will be treated as containing a zero. Otherwise, the targeted cell must contain an 8-byte value (interpreted as a 64-bit big-endian signed integer), or the entire request will fail.
