operator ()

System.Classes.TInterfacedPersistent

AfterConstructionObtains a reference to the Owner's interface.
Create
Destroy
QueryInterfaceReturns a reference to a specified interface if the object supports that interface.
_AddRefIncrements the reference count for the interfaced object's interface.
_ReleaseDecrements the reference count for the interfaced object's interface.
operator ()

System.Classes.TPersistent

AssignCopies the contents of another similar object.
AssignToCopies the properties of an object to a destination object.
Create
DefinePropertiesProvides an interface for a method that reads and writes otherwise unpublished data.
DestroyDestroys the TPersistent instance and frees its memory.
GetNamePathReturns the name of the object as it appears in the Object Inspector.
GetOwnerReturns the owner of an object.

System.TObject

AfterConstructionResponds after the last constructor has executed.
BeforeDestructionResponds before the first destructor executes.
ClassInfoReturns a pointer to the run-time type information (RTTI) table for the object type.
ClassNameReturns a string indicating the type of the object instance (as opposed to the type of the variable passed as an argument).
ClassNameIsDetermines whether an object is of a specific type.
ClassParentReturns the type of the immediate ancestor of a class.
ClassTypeReturns the class reference for the object's class.
CleanupInstancePerforms finalization on long strings, variants, and interface variables within a class.
CreateConstructs an object and initializes its data before the object is first used.
DefaultHandlerProvides the interface for a method that processes message records.
DestroyDisposes of an object instance.
DispatchCalls message-handling methods for the object, based on the contents of the Message parameter.
EqualsChecks whether the current instance and the parameter are equal.
FieldAddressReturns the address of a published object field.
FreeDestroys an object and frees its associated memory, if necessary.
FreeInstanceDeallocates memory allocated by a previous call to the NewInstance method.
GetHashCodeReturns an integer containing the hash code.
GetInterfaceRetrieves a specified interface.
GetInterfaceEntryReturns the entry for a specific interface implemented in a class.
GetInterfaceTableReturns a pointer to a structure containing all of the interfaces implemented by a given class.
InheritsFromDetermines the relationship of two object types.
InitInstanceInitializes a newly allocated object instance to all zeros and initializes the instance's virtual method table pointer.
InstanceSizeReturns the size in bytes of each instance of the object type.
MethodAddressReturns the address of a class method by name.
MethodNameReturns the name of a class method by address.
NewInstanceAllocates memory for an instance of an object type and returns a pointer to that new instance.
QualifiedClassNameReturns the qualified name of the class.
SafeCallExceptionHandles exceptions in methods declared using the safecall calling convention.
ToStringReturns a string containing the class name.
UnitNameReturns the name of the unit where the class is defined.
UnitScopeReturns the class's unit scope.
