constructor Create  reintroduce overload virtual    (declared in TROComplexType)

Creates a new instance.

constructor Create

constructor Create (TCollection)  overload override    (declared in TROComplexType)

Creates a new instance with given parameter.

constructor Create(aCollection: TCollection)

Parameters:

  • aCollection: collection

Assign  override

Copies data from a given source.

procedure Assign(Source: TPersistent)

Parameters:

  • Source: Instance whose properties will be copied

AssignTo  override    (declared in TROComplexType)
