Description
Allocates memory for each instance of an interfaced object. {{#multireplace:System.Threading.TThreadPool.TAbstractWorkerData.NewInstance|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}} inherits from {{#multireplace:System.TInterfacedObject.NewInstance|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}. All content below this line refers to {{#multireplace:System.TInterfacedObject.NewInstance|H21=!|H25=%|H28=(|H29=)|H2A=*|H2B=+|H2F=/|H3C=<|H3D==|H3E=>|H5B=[|H5D=]|H5E=^|H7C=|}}.
Allocates memory for each instance of an interfaced object.
All constructors call NewInstance automatically. NewInstance calls InstanceSize to determine how much memory to allocate from the heap to contain a particular instance. Do not call NewInstance directly.
TInterfacedObject overrides NewInstance to increment the reference count when a new instance is created. This prevents any constructor from accidentally deleting the instance due to a RefCount of zero. The AfterConstruction method decrements the value of RefCount after all constructors have executed.
