Interface Tracker

All Known Implementing Classes:
TrackerImpl, TrackerImplEx

public interface Tracker

Bind tracker to maintain a binding dependency graph. e.g. @{a.b.c, save-onchange:d.e.f} then it forms a dependency from d.e.f to a.b.c for save.

              java.lang.Object propName,
              java.lang.Object value)
Tie a property to its corresponding value under the specified Component.

Parameters:
comp - the associated component
base - the base object of the property
script - the field script
propName - the resolved property name from the field script
value - the value of the property

getLoadBindings

java.util.Set<LoadBinding> getLoadBindings(java.lang.Object base,

Returns all bindings that associated with the specified property.

Parameters:
base - base object
propName - property name
Returns:
all LoadBindings that associated with the specified property.
