NAME¶
Rose::DB::Object::Metadata::Column::Numeric - Numeric column metadata.
SYNOPSIS¶
use Rose::DB::Object::Metadata::Column::Numeric;
$col = Rose::DB::Object::Metadata::Column::Numeric->new(...);
$col->make_methods(...);
...
DESCRIPTION¶
Objects of this class store and manipulate metadata for numeric columns in a
database. Column metadata objects store information about columns (data type,
size, etc.) and are responsible for creating object methods that manipulate
column values.
This class inherits from Rose::DB::Object::Metadata::Column::Scalar. Inherited
methods that are not overridden will not be documented a second time here. See
the Rose::DB::Object::Metadata::Column::Scalar documentation for more
information.
METHOD MAP¶
- "get_set"
- Rose::DB::Object::MakeMethods::Generic, scalar,
"interface => 'get_set', ..."
- "get"
- Rose::DB::Object::MakeMethods::Generic, scalar,
"interface => 'get', ..."
- "get_set"
- Rose::DB::Object::MakeMethods::Generic, scalar,
"interface => 'set', ..."
See the Rose::DB::Object::Metadata::Column documentation for an explanation of
this method map.
OBJECT METHODS¶
- precision [INT]
- Get or set the precision of the numeric value. The
precision is the total count of significant digits in the whole number.
That is, the number of digits to both sides of the decimal point. For
example, the number 23.5141 has a precision of 6.
- scale [INT]
- Get or set the scale of the numeric value. The scale is the
count of decimal digits in the fractional part, to the right of the
decimal point. For example, the number 23.5141 has a scale of 4. Integers
can be considered to have a scale of zero.
- type
- Returns "numeric".
