void addDataFlavor ( char* dataFlavor )

Add the data flavor, indicating that this transferable can receive this type of flavor

Arguments:

dataFlavor: a new data flavor to handle

nsISupportsArray flavorsTransferableCanExport ( )

Computes a list of flavors (mime types as nsISupportsCString) that the transferable can export, either through intrinsic knowledge or output data converters.

nsISupportsArray flavorsTransferableCanImport ( )

Computes a list of flavors (mime types as nsISupportsCString) that the transferable can accept into it, either through intrinsic knowledge or input data converters.

void getAnyTransferData ( out char* flavor , out nsISupports data , out PRUint32 dataLen )

Returns the best flavor in the transferable, given those that have been added to it with AddFlavor()

Arguments:

flavor: (out parameter) the flavor of data that was retrieved

data: the data. Some variant of class in nsISupportsPrimitives.idl

dataLen: the length of the data

void getTransferData ( char* flavor , out nsISupports data , out PRUint32 dataLen )

Given a flavor retrieve the data.

Arguments:

flavor: (in parameter) the flavor of data to retrieve

data: the data. Some variant of class in nsISupportsPrimitives.idl

dataLen: the length of the data

PRBool isLargeDataSet ( )

Returns true if the data is large.

void removeDataFlavor ( char* dataFlavor )

Removes the data flavor matching the given one (string compare) and the data that goes along with it.

Arguments:

dataFlavor: a data flavor to remove

void setTransferData ( char* flavor , nsISupports data , PRUint32 dataLen )

Sets the data in the transferable with the specified flavor. The transferable will maintain its own copy the data, so it is not necessary to do that beforehand.

Arguments:

flavor: the flavor of data that is being set

data: the data, some variant of class in nsISupportsPrimitives.idl, or an nsIFlavorDataProvider (see above)

dataLen: the length of the data, or 0 if passing a nsIFlavorDataProvider
