Description

constructor Create(AManager: TItemsManager); override;

destructor Destroy; override;

procedure AddProperties(const Result: Props.TProperties); override;

procedure Allocate(ASize: Integer);

Allocates an empty data buffer or changes allocated size of an existing one

function Convert(OldFormat, NewFormat: Integer): Boolean; virtual;

Should perform actual conversion from old format to a new one and return True if the conversion is possible and successful

function GetElementSize: Integer; virtual;

Returns size of each element in resource

function GetItemSize(CountChilds: Boolean): Integer; override;

class function IsAbstract: Boolean; override;

function Load(Stream: Basics.TStream): Boolean; override;

Loads the resource from a stream

function LoadData(Stream: Basics.TStream): Boolean; virtual;

Read resource's data from the specified stream

function Save(Stream: Basics.TStream): Boolean; override;

Saves the resource to a stream

procedure SetAllocated(ASize: Integer; AData: Pointer);

Sets already allocated and probably ready to use data
