Alzabo::ColumnDefinition(3pm) User Contributed Perl Documentation Alzabo::ColumnDefinition(3pm)

NAME

Alzabo::ColumnDefinition - Holds the type attribute for a column

SYNOPSIS

  my $def = $column->definition;
  print $def->type;

DESCRIPTION

This object holds information on a column that might need to be shared with another column. The reason for this is that if a column is a key in two or more tables, then some of the information related to that column should change automatically for all tables (and all columns) whenever it is changed anywhere. Right now this is only type ('VARCHAR', 'NUMBER', etc) information. This object also has an 'owner', which is the column which created it.

METHODS

type

Returns the object's type as a string.

length

Returns the length attribute of the column, or undef if there is none.

precision

Returns the precision attribute of the column, or undef if there is none.

owner

Returns the "Alzabo::Column" object that owns this definitions (the column that created it).
