Detailed Description

DataContext acts as a container for data.

Member Function Documentation

◆ getData()

DataObject getData ( )

Retrieves the root object of the underlying data tree.

Needs to be implemented by the derived class.

Returns: Returns data object that is the root of the data tree.

Reimplemented in DataSource.

◆ lookupDataContext()

DataContext lookupDataContext ( String relativePath )

Performs object look-up by path.

Parameters

relativePath Path of the object where to look at, separated by '.'.

Returns: Data object that was found, or empty handle if there was no such object.

Reimplemented in DataSource.

◆ notifyModified()

void notifyModified ( )

Triggers modification procedure in this data context, which invokes the subscriptions.

Should be called by derived classes whenever the value of the object is changed.
