	`property Font: TAdFont read FFont write FFont;`
	`property AutoFreeFont: boolean read FAutoFreeFont write FAutoFreeFont;`

	`constructor Create;`
Creates an instance of TAdFontDataKey.

	`destructor Destroy; override;`
Destroys the instance of TAdFontDataKey.

function Hash: integer; override;

Returns a hash value that represents this font data hash. The hash value is calculated once when "InsertData" is called.

	`property MetaData: Pointer read FMetaData;`
Pointer to the font metadata

	`property MetaDataSize: Cardinal read FMetaDataSize;`
Size of the metadata stored in the metadata property.

	`property Font: TAdFont read FFont write FFont;`
The font that is attached to this font datakey

	`property AutoFreeFont: boolean read FAutoFreeFont write FAutoFreeFont;`
If true, the font will be freed with this data key.

	`function Equal(AItem:TAdMapKey):boolean; override;`
Compares AItem to itsself and returns whether the two font data keys are equal.

	`procedure InsertData(AMetaData:Pointer; AMetaDataSize: Cardinal);`
Stores the font meta data in the key and calculates the hash value.

	`procedure SaveToStream(AStream:TStream);`
Saves the key metadata to a stream.

	`procedure LoadFromStream(AStream:TStream);`
Loads the key metadata from a stream.
