Class MultiPropertyModel<T>

java.lang.Object

org.apache.wicket.model.AbstractPropertyModel<T>

org.apache.wicket.model.PropertyModel<T>

com.neurosys.site.wicket.model.MultiPropertyModel<T>

Type Parameters:

T -

All Implemented Interfaces:

Serializable, org.apache.wicket.IClusterable, org.apache.wicket.model.IChainingModel<T>, org.apache.wicket.model.IDetachable, org.apache.wicket.model.IModel<T>, org.apache.wicket.model.IObjectClassAwareModel<T>, org.apache.wicket.model.IPropertyReflectionAwareModel

public class MultiPropertyModel<T>
extends org.apache.wicket.model.PropertyModel<T>

A PropertyModel allows set multiple expressions (properties) in a model. The AbstractPropertyModel.getPropertyExpression() is the primary expression applicable for AbstractPropertyModel.getObject(), however a set process can be mapped to multiple expressions. This helps in binding a component to multiple fields within the Object model.

Constructor Detail

MultiPropertyModel

public MultiPropertyModel(Object modelObject,
                          String expression)

Construct with a wrapped (IModel) or unwrapped (non-IModel) object and a property expression that works on the given model.

Parameters:

modelObject - The model object, which may or may not implement IModel

expression - Property expression for property access

MultiPropertyModel

public MultiPropertyModel(Object modelObject,
                          String[] expressions)

Construct with a wrapped (IModel) or unwrapped (non-IModel) object and a property expressions[0] that works on the given model.

Parameters:

modelObject - The model object, which may or may not implement IModel

expressions - Array of String Property expressions for property setting, where expressions[0] is specific for access

Method Detail

setObject

public void setObject(T object)

Applies the property expression on the model object using the given object argument.

Specified by:

setObject in interface org.apache.wicket.model.IModel<T>

Overrides:

setObject in class org.apache.wicket.model.AbstractPropertyModel<T>

Parameters:

object - The object that will be used when setting a value on the model object

See Also:

IModel#setObject(T)

toString

public String toString()

Overrides:

toString in class org.apache.wicket.model.PropertyModel<T>

See Also:

Object.toString()

getExpressions

public String[] getExpressions()

getFilter

public org.apache.commons.collections.Predicate getFilter()

When setting multiple expressions, it maybe desired to filter which expressions should be used or not based on runtime conditions on the object being set.
Predicate.evaluate(Object) = true implies that the expression will not be set

setFilter

public void setFilter(org.apache.commons.collections.Predicate filter)

When setting multiple expressions, it maybe desired to filter which expressions should be used or not based on runtime conditions on the object being set.
Predicate.evaluate(Object) = true implies that the expression will not be set
