Interface IlpImageRepository

All Known Implementing Classes:

IlpDefaultImageRepository, IltDefaultImageRepository, IltDefaultImageRepository

public interface IlpImageRepository

Image repository where images can be accessed by their relative location. The image repository serves two primary functions:

• Provides an association between an image and the file location of the image.
• Provides memory management - reuse of images that have already been loaded. By keeping one reusable instance of an image in a repository, the image does not need to be loaded in memory multiple times.

Since:

JTGO 3.0
