Communication between Features¶
Features can communicate together through the use of Shared Interfaces. This mechanism is described in Shared Interfaces section.
Kernel Types Converter¶
The Shared Interface mechanism allows to transfer an object instance of a Kernel type from one Feature to an other (see Transferable Types section).
To do that, the Kernel must register a new Kernel type converter. See the Converter class and Kernel.addConverter() method for more details.
The table below shows some converters defined in the com.microej.library.util#kf-util library.
