Public methods

getCurrentIndex

Added in API level 1

abstract fun getCurrentIndex(): Int

Get the index of the current history item. This index can be used to directly index into the array list.

Return
`Int`	The current index from 0...n or -1 if the list is empty.

getCurrentItem

Added in API level 1

abstract fun getCurrentItem(): WebHistoryItem?

Return the current history item. This method returns null if the list is empty.

Return
`WebHistoryItem?`	The current history item.

getItemAtIndex

Added in API level 1

abstract fun getItemAtIndex(index: Int): WebHistoryItem!

Get the history item at the given index. The index range is from 0...n where 0 is the first item and n is the last item.

Parameters
`index`	Int: The index to retrieve.

getSize

Added in API level 1

abstract fun getSize(): Int

Get the total size of the back/forward list.

Return
`Int`	The size of the list.

Protected methods

clone

Added in API level 1

protected abstract fun clone(): WebBackForwardList

Clone the entire object to be used in the UI thread by clients of WebView. This creates a copy that should never be modified by any of the webkit package classes. On Android 4.4 and later there is no need to use this, as the object is already a read-only copy of the internal state.

Return
`WebBackForwardList`	a clone of this instance.

Exceptions
`java.lang.CloneNotSupportedException`	if the object's class does not support the `Cloneable` interface. Subclasses that override the `clone` method can also throw this exception to indicate that an instance cannot be cloned.
