FdcDecimalField class

Decimal field metadata.

precision and scale are required because decimal capacity is part of the dataset schema, not a grid/editor formatting preference.

no setterinherited
isCalculated → bool
True when the field value is derived by calculatedValue.
no setterinherited
isKey → bool
Whether this field participates in the dataset record identity.
finalinherited
isPersistent → bool
True when the field participates in persistence-oriented dataset output.

isReadOnly → bool
True when normal dataset editing must not write this field.
no setterinherited
label → String?
Display label shown to the user.
finalinherited
maxValue → num?
The max value.
final
minValue → num?
The min value.
final
name → String
Original field name casing used for export/display metadata.
finalinherited
persistent → bool?
Controls whether the field participates in persistence-oriented outputs such as FdcDataSet.changeSet and FdcDataSet.toMaps.
finalinherited
precision → int
The precision.
final

A representation of the runtime type of the object.
no setterinherited
scale → int
The scale.
final
storage → FdcFieldStorage
Persistence/storage metadata consumed by adapters.
finalinherited
validator → FdcFieldValidator?
