nsISupports
Last changed in Gecko 6.0 (Firefox 6.0 / Thunderbird 6.0 / SeaMonkey 2.3)You can copy an object into an nsIStructuredCloneContainer using initFromVariant() or initFromBase64(). it is an error to initialize an nsIStructuredCloneContainer more than once.
Once you've initialized the container, you can get a copy of the object it stores by calling deserializeToVariant(). You can also get a base-64-encoded string containing a copy of the container's serialized data, using getDataAsBase64().

Attributes
| Attribute | Type | Description |

Methods
deserializeToVariant()
Deserialize the object this container holds, returning it wrapped as an nsIVariant.
nsIVariant deserializeToVariant();
Parameters
None.
Return value
An nsIVariant.
getDataAsBase64()
Get this structured clone container's data as a base-64-encoded string.
AString getDataAsBase64();
Parameters
None.
Return value
A base-64-encoded string.
initFromBase64()
Initialize this structured clone container from a base-64-encoded byte stream.
void initFromBase64( in AString aData, in unsigned long aFormatVersion );
Parameters
aData- A base-64-encoded byte stream.
aFormatVersion- The version of the structured clone algorithm which was used to generate
aData.
initFromVariant()
Initialize this structured clone container so it contains a clone of the given variant.
void initFromVariant( in nsIVariant aData );
Parameters
aData- A
nsIVariant, must be backed by ajsval.
