Interface nsIKeyValueEnumeratorType

An enumerator of key/value pairs. Although its methods are similar to those of nsISimpleEnumerator, this interface's getNext() method returns an nsIKeyValuePair rather than an nsISupports, so consumers don't need to QI it to that interface; but this interface doesn't implement the JS iteration protocol (because the Rust-XPCOM bindings don't yet support it), which is another reason why you should use the kvstore.jsm module from JS instead of accessing this API directly.

Methods

AddRef

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

    Returns

    The resulting reference count.

    Returns number

QueryInterface

  • Parameters

    • aIID: object
    • Optional aInstancePtr: object

    Returns any

  • A run time mechanism for interface discovery.

    Returns

    NS_OK if the interface is supported by the associated instance, NS_NOINTERFACE if it is not.

    aInstancePtr must not be null.

    Parameters

    • aIID: object

      [in] A requested interface IID

    • aInstancePtr: object

      [out] A pointer to an interface pointer to receive the result.

    Returns void

Release

  • 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.

    Returns number

getNext

  • Returns nsIKeyValuePair

hasMoreElements

  • Returns bool
