The WebHistory class represents a session history associated with a WebEngine instance. A single instance of WebHistory for a particular web engine can be obtained through the WebEngine#getHistory() method. The history is basically a list of entries. Each entry represents a visited page and it provides access to relevant page info, such as URL, title, and the date the page was last visited. Entries in the list are arranged in the order in which the corresponding pages were visited from oldest to newest. The list can be obtained by using the getEntries() method. The history and the corresponding list of entries change as WebEngine navigates across the web. The list may expand or shrink depending on browser actions. These changes can be listened to by the javafx.collections.ObservableList API that the list exposes. The index of the history entry associated with the currently visited page is represented by the currentIndexProperty. The current index can be used to navigate to any entry in the history by using the go(int) method. The maxSizeProperty() sets the maximum history size, which is the size of the history list.

Method Detail

currentIndexProperty back to summary

currentIndexProperty	back to summary
public ReadOnlyIntegerProperty currentIndexProperty() Defines the index of the current `Entry` in the history. The current entry is the entry associated with the currently loaded page. The index belongs to the range of `(index >= 0 && index < getEntries().size())`. Returns:ReadOnlyIntegerProperty the currentIndex property

public ReadOnlyIntegerProperty currentIndexProperty()

Defines the index of the current Entry in the history. The current entry is the entry associated with the currently loaded page. The index belongs to the range of (index >= 0 && index < getEntries().size()).

Returns:ReadOnlyIntegerProperty: the currentIndex property

getCurrentIndex	back to summary

go	back to summary
public void go(int offset) throws IndexOutOfBoundsException Navigates the web engine to the URL defined by the `Entry` object within the specified position relative to the current entry. A negative `offset` value specifies the position preceding to the current entry, and a positive `offset` value specifies the position following the current entry. For example, -1 points to the previous entry, and 1 points to the next entry, corresponding to pressing a web browser's 'back' and 'forward' buttons, respectively. The zero `offset` value is silently ignored (no-op). The effective entry position should belong to the rage of [0..size-1]. Otherwise, `IndexOutOfBoundsException` is thrown. Parameters offset:int a negative value specifies a position preceding the current entry, a positive value specifies a position following the current entry, zero value causes no effect Exceptions IndexOutOfBoundsException: if the effective entry position is out of range

public void go(int offset) throws IndexOutOfBoundsException

Navigates the web engine to the URL defined by the Entry object within the specified position relative to the current entry. A negative offset value specifies the position preceding to the current entry, and a positive offset value specifies the position following the current entry. For example, -1 points to the previous entry, and 1 points to the next entry, corresponding to pressing a web browser's 'back' and 'forward' buttons, respectively. The zero offset value is silently ignored (no-op). The effective entry position should belong to the rage of [0..size-1]. Otherwise, IndexOutOfBoundsException is thrown.

Parameters

offset:int: a negative value specifies a position preceding the current entry, a positive value specifies a position following the current entry, zero value causes no effect

Exceptions

IndexOutOfBoundsException:: if the effective entry position is out of range

maxSizeProperty	back to summary
public IntegerProperty maxSizeProperty() Defines the maximum size of the history list. If the list reaches its maximum and a new entry is added, the first entry is removed from the history. The value specified for this property can not be negative, otherwise `IllegalArgumentException` is thrown. Returns:IntegerProperty the maxSize property Default Value 100

public IntegerProperty maxSizeProperty()

Defines the maximum size of the history list. If the list reaches its maximum and a new entry is added, the first entry is removed from the history.
