This abstract class represents a binding between a model and a target. Newly
created instances need to be added to a data binding context using
init(DataBindingContext)
.

Binding
public Binding(
IObservable target,
IObservable model)
- Creates a new binding.
-
Parameters:
-
target
- target observable -
model
- model observable
init
public final void init(
DataBindingContext context)
- Initializes this binding with the given context and adds it to the list
of bindings of the context.
Subclasses may extend, but must call the super implementation.
-
-
Parameters:
-
context
-
preInit
protected abstract void preInit()
- Called by
init(DataBindingContext)
after setting
context
but before adding this binding to the context.
Subclasses may use this method to perform initialization that could not
be done in the constructor. Care should be taken not to cause any events
while running this method.
-
postInit
protected abstract void postInit()
- Called by
init(DataBindingContext)
after adding this binding to
the context. Subclasses may use this method to perform initialization
that may cause events to be fired, including BindingEvents that are
forwarded to the data binding context.
-
updateTargetToModel
public abstract void updateTargetToModel()
- Updates the model's state from the target's state at the next reasonable
opportunity. There is no guarantee that the state will have been updated
by the time this call returns.
-
updateModelToTarget
public abstract void updateModelToTarget()
- Updates the target's state from the model's state at the next reasonable
opportunity. There is no guarantee that the state will have been updated
by the time this call returns.
-
validateTargetToModel
public abstract void validateTargetToModel()
- Validates the target's state at the next reasonable
opportunity. There is no guarantee that the validation status will have been updated
by the time this call returns.
-
validateModelToTarget
public abstract void validateModelToTarget()
- Validates the model's state at the next reasonable
opportunity. There is no guarantee that the validation status will have been updated
by the time this call returns.
-
dispose
public void dispose()
- Disposes of this Binding. Subclasses may extend, but must call super.dispose().
