Method Detail

getBinder

public DataBinder getBinder()

Gets the associated Data Binder of this Binding.

getComponent

public Component getComponent()

Gets the associated Component of this Binding.

getAttr

public java.lang.String getAttr()

Get component attribute name.

getArgs

public java.util.Map<java.lang.Object,java.lang.Object> getArgs()

Get generic arguments.

getExpression

public java.lang.String getExpression()

Get bean expression, e.g. a.b.c.

getSaveWhenEvents

public java.util.Set<java.lang.String> getSaveWhenEvents()

Get save-when event expression.

getAfterWhenEvents

public java.util.Set getAfterWhenEvents()

Get save-after event expression.

getLoadWhenEvents

public java.util.LinkedHashSet<java.lang.String> getLoadWhenEvents()

Get load-when event expression set.

getLoadAfterEvents

isLoadable

public boolean isLoadable()

Whether the binding is loadable.

isSavable

public boolean isSavable()

Whether the binding is savable.

getConverter

public TypeConverter getConverter()

Get the TypeConverter.

loadAttribute

public void loadAttribute(Component comp)

load bean value into the attribute of the specified component.

Parameters:

comp - the component.

getBean

public java.lang.Object getBean(Component comp)

Returns the associated bean of this binding; e.g., for a binding to the bean "a.b.c", this will return the bean associated to "a.b" (and c is the property name).

Note if the expression is associated to a single variable; e.g. "a" only, this method returns null.

Parameters:

comp -

Returns:

the associated bean of this binding.

Parameters:

comp - the component.

bean - the bean value.

saveAttribute

public void saveAttribute(Component comp)

save into bean value from the attribute of the specified component.

Parameters:

comp - the component.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
