InternalResourceMap (wcomponents-core 1.5.24 API)

java.lang.Object
- com.github.bordertech.wcomponents.InternalResourceMap

```
public final class InternalResourceMap
extends Object
```
The ImageResourceMap map keeps a reference to all internal resources within an application. It is used by the WContentHelperServlet to efficiently serve binary data without having to go through normal WComponent processing.
Two things stop this map from consuming excessive amounts of memory:
1. InternalResources are files which are present in the classpath. There will be a finite set.
2. The InternalResource implementation does not hold the file data, just a reference to the file.
