Static Methods

create

(): ILabelOwnerGridConstraintProvider
static
Creates an implementation of the interface ILabelOwnerGridConstraintProvider from the given definition.
The given object must contain exactly the abstract members of the ILabelOwnerGridConstraintProvider interface. No member may be omitted and no additional members can be added. While additional custom members can later be added directly on the instance, this is discouraged.
static

Parameters

Return Value

ILabelOwnerGridConstraintProvider
An instance of the ILabelOwnerGridConstraintProvider interface based on the given definition.
