nsIStructuredCloneContainer

This interface acts as a container for an object serialized using the
structured clone algorithm.

You can copy an object into an nsIStructuredCloneContainer using
initFromVariant or initFromBase64. It’s 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.

Methods

initFromJSVal(aData)

Initialize this structured clone container so it contains a clone of the
given jsval.

initFromBase64(aData, aFormatVersion)

Initialize this structured clone container from a base-64-encoded byte
stream, stored in aData. aFormatVersion should be the version of the
structured clone algorithm which was used to generate aData.

deserializeToVariant()

Deserialize the object this container holds, returning it wrapped as
an nsIVariant.

getDataAsBase64()

Get this structured clone container’s data as a base-64-encoded string.

Attributes

serializedNBytes

Get the size in bytes of this container’s serialized data.

formatVersion

Get the version of the structured clone algorithm which was used to
generate this container’s serialized buffer.
