public boolean
equals(Object obj)

Overrides java.lang.Object.equals.

Implements java.util.Map.equals.

Compares the specified object with this map for equality.

public int

Returns:

a hash code for this ReadOnlyMapProperty object.
hashCode()

Overrides java.lang.Object.hashCode.

public ReadOnlyMapProperty()

The constructor of ReadOnlyMapProperty.

Method Detail

bindContentback to summary
public void bindContent(ObservableMap<K, V> map)

Creates a content binding between the javafx.collections.ObservableMap, that is wrapped in this ReadOnlyMapProperty, and another ObservableMap.

A content binding ensures that the content of the wrapped ObservableMaps is the same as that of the other map. If the content of the other map changes, the wrapped map will be updated automatically. Once the wrapped list is bound to another map, you must not change it directly.

Parameters
map:ObservableMap<K, V>

the ObservableMap this property should be bound to

Exceptions
NullPointerException:
if map is null
IllegalArgumentException:
if map is the same map that this ReadOnlyMapProperty points to
bindContentBidirectionalback to summary
public void bindContentBidirectional(ObservableMap<K, V> map)

Creates a bidirectional content binding of the javafx.collections.ObservableMap, that is wrapped in this ReadOnlyMapProperty, and another ObservableMap.

A bidirectional content binding ensures that the content of two ObservableMaps is the same. If the content of one of the maps changes, the other one will be updated automatically.

Parameters
map:ObservableMap<K, V>

the ObservableMap this property should be bound to

Exceptions
NullPointerException:
if map is null
IllegalArgumentException:
if map is the same map that this ReadOnlyMapProperty points to
equalsback to summary
public boolean equals(Object obj)

Overrides java.lang.Object.equals.

Implements java.util.Map.equals.

Doc from java.util.Map.equals.

Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings. More formally, two maps m1 and m2 represent the same mappings if m1.entrySet().equals(m2.entrySet()). This ensures that the equals method works properly across different implementations of the Map interface.

Annotations

public int hashCode()

Overrides java.lang.Object.hashCode.

Implements java.util.Map.hashCode.

Returns a hash code for this ReadOnlyMapProperty object.

Returns:int

a hash code for this ReadOnlyMapProperty object.

Annotations
@Override
toStringback to summary
public String toString()

Overrides java.lang.Object.toString.

Returns a string representation of this ReadOnlyMapProperty object.

Returns:String

a string representation of this ReadOnlyMapProperty object.

Annotations
@Override
unbindContentback to summary
public void unbindContent(Object object)

Deletes a content binding between the javafx.collections.ObservableMap, that is wrapped in this ReadOnlyMapProperty, and another Object.

Parameters
object:Object

the Object to which the binding should be removed

Exceptions
NullPointerException:
if object is null
IllegalArgumentException:
if object is the same map that this ReadOnlyMapProperty points to
unbindContentBidirectionalback to summary
public void unbindContentBidirectional(Object object)

Deletes a bidirectional content binding between the javafx.collections.ObservableMap, that is wrapped in this ReadOnlyMapProperty, and another Object.

Parameters
object:Object

the Object to which the bidirectional binding should be removed

Exceptions
NullPointerException:
if object is null
IllegalArgumentException:
if object is the same map that this ReadOnlyMapProperty points to
