Returns:

Returns the maxCachedFiles.

setMaxCachedFiles

public void setMaxCachedFiles(int maxCachedFiles)

Parameters:

maxCachedFiles - The maxCachedFiles to set.

flushCache

public void flushCache()

lookup

public HttpContent lookup(String pathInContext)
                   throws IOException

Get a Entry from the cache. Get either a valid entry object or create a new one if possible.

Throws:

IOException - Problem loading the resource

isCacheable

protected boolean isCacheable(Resource resource)

Parameters:

resource -

Returns:

True if the resource is cacheable. The default implementation tests the cache sizes.
