Type_Tie

Type_Tie = 6

Example​

procedure ScriptEvent(var Value: variant);
begin
  Value := GetUomTypeCode(Type_Tie); // 'Tie'
end;

Usage​

Type_Tie identifies the Tie UOM classification as Uom_Type.Num value 6 for Velox scripts and product metadata.

Additional Technical Info​

Type_Tie is the script-visible LongInt identifier for the Tie UOM classification. Its fixed value is 6, paired with Type_Tie_String.

It classifies a unit-of-measure record; it does not define an actual UOM code, pack size, price, quantity, conversion factor or inventory amount.

Implementation

Velox declares and registers fixed value 6. GetUomTypeCode maps it to Tie; GetUomTypeNum performs the reverse mapping. The numeric name is in the tag map, so <!Type_Tie!> expands to 6.

Fresh-build VxData seeds Uom_Type row 6 with Description Tie. The database describes the domain as controlling whether UOMs can be used in quantity, tie and pallet contexts; a null Uom.TypeNum means the UOM is global.

The converter pair contains a distinct branch for this value and canonical text.

Behaviour

Text-to-number conversion is case-insensitive but non-trimming. Unsupported or padded text returns Null; number-to-text conversion returns Null for Null or an unsupported number.

Use this family only for UOM classification. It does not validate Uom.Code, UomCode, product pack data or price applicability.

Edge cases and quirks

  • Type_Quantity and Type_Unit both equal 1; Type_Quantity_String and Type_Unit_String both equal Unit. After evaluation they are indistinguishable.
  • The duplicate value/text is intentional in native source, not a separate database row named Quantity.
  • The tag expansion produces the number 6, not the text Tie.
  • Text conversion accepts case differences but not leading/trailing whitespace.
  • A null Uom.TypeNum has database meaning (global UOM); none of these constants represents null/global.
  • PascalScript retains no UOM-domain type after evaluation, so same-valued constants from other families are not interchangeable.

Side effects

Reading Type_Tie, comparing it, expanding its tag or using the fixed converters has no I/O or state-changing effect.

Errors

Reading the constant does not raise an error. Converter misses return Null. Persisting a number outside the seeded/configured UOM type table can fail a foreign key.

Performance and concurrency

This is immutable compiled metadata. Access and the short fixed converter cases are constant-time for practical purposes and carry no shared mutable UOM state.

Remarks

The example is source-reviewed and non-destructive. It does not load a UOM record or calculate quantities.
