Interface nsIURIMutatorType

Increases the reference count for this interface. The associated instance will not be deleted unless the reference count is returned to zero.

Returns

A run time mechanism for interface discovery.

Returns

aInstancePtr must not be null.

Decreases the reference count for this interface. Generally, if the reference count returns to zero, the associated instance is deleted.

Returns

The resulting reference count.

If you setHostPort to a value that only has a host part, the port will not be reset. To reset the port set it to -1 beforehand. If setting the host succeeds, this method will return NS_OK, even if setting the port fails (error in parsing the port, or value out of range)

Setting the scheme outside of a protocol handler implementation is highly discouraged since that will generally lead to incorrect results.

This setter is different from all other setters because it may be used to initialize the object. We define it separately allowing mutator implementors to define it separately, while the rest of the setters may be simply forwarded to the mutable URI.
