Interface Technology.ValueMutated<D>

Type Parameters:

D - internal type of the technology

All Superinterfaces:

Technology<D>

Enclosing interface:

Technology<Data>

public static interface Technology.ValueMutated<D>
extends Technology<D>

Some technologies are more effective when number of calls between Java and JavaScript is limited - to do that when a value of property is changed they should implement this additional interface.

Since:

0.7.6

Method Detail

valueHasMutated

void valueHasMutated(D data,
                   String propertyName,
                   Object oldValue,
                   Object newValue)

Model for given data has changed its value. The technology is supposed to update its state (for example DOM nodes associated with the model). The update usually happens asynchronously.

If both oldValue and newValue are null then the real value of the technology is not known.

If this method is present, then it is called instead of old, plain Technology.valueHasMutated(java.lang.Object, java.lang.String) which is never called by the infrastructure then.

Parameters:

data - technology's own representation of the model

propertyName - name of the model property that changed

oldValue - provides previous value of the property

newValue - provides new value of the property
