Methods
#append_value
def append_value() -> ::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.
#append_value=
def append_value=(value) -> ::String
Parameter
-
value (::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.
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
def column_qualifier() -> ::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.
#column_qualifier=
def column_qualifier=(value) -> ::String
Parameter
- value (::String) — 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
def family_name() -> ::String
Returns
-
(::String) — The name of the family to which the read/modify/write should be applied.
Must match
[-_.a-zA-Z0-9]+
#family_name=
def family_name=(value) -> ::String
Parameter
-
value (::String) — 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
def increment_amount() -> ::Integer
Returns
-
(::Integer) — 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.
#increment_amount=
def increment_amount=(value) -> ::Integer
Parameter
-
value (::Integer) — 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.
Returns
-
(::Integer) — 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.
