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_method(...);
  ...

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.

OBJECT METHODS

default [VALUE]

Get or set the default value of the column.

method_maker_class

Returns Rose::DB::Object::MakeMethods::Generic.

method_maker_type

Returns scalar.

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".
