Udf

A UDF is a set of properties that define a table column and/or form field. Zoglair uses UDFs for its settings. Unless you are developing addons, there is no need to deal with this table.

The udf form contains the following fields:

• Addon ID
  The ID of the Addon row, to which this udf belongs.
• Table
  A table to which the udf is attached. The top item of the drop-down list is “settings”. That is not a real table as it does not exist in the database (neither in the codebase). It is a runtime synthesized (~virtual) one.
• Group
  A group name to distinguish udfs of the same table.
• Order
  A arbitrary integer for listing udfs in a certain order, since an alphabetical listing is not always desirable.
• Form
• Name
• Type
• Attr
• Size
• Regx
• Meta
• Null
  Standard column attributes, as described in the Developer Guide.
