VariableResolver (Apache Felix Web Management Console 4.8.8 API)

All Known Implementing Classes:

DefaultVariableResolver
```
public interface VariableResolver
```
The VariableResolver interface defines the API for an object which may be provided by plugins to provide replacement values for variables in the generated content.
Plugins should call the WebConsoleUtil.setVariableResolver(javax.servlet.ServletRequest, VariableResolver) method to provide their implementation for variable resolution.
The main use of such a variable resolver is when a plugin is using a static template which provides slots to place dynamically generated content parts.
Note: The variable resolver must be set in the request before the response writer is retrieved calling the ServletRequest.getWriter() method. Otherwise the variable resolver will not be used for resolving variables.
