Interface SymbolImageData

All Known Implementing Classes:

GuiSymbols.GuiSymbolImage

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface SymbolImageData

This interface is a marker for a particular GUI API's means of storing image data associated with an APRS or OpenTRAC symbol. Because the data types are UI-platform-specific, there are no fields defined here; the using classes for a UI should cast this interface to the UI-specific implementing class.
