Returns the filesCache implementation used to cache files

Usage

From source file:egovframework.rte.fdl.filehandling.FilehandlingServiceTest.java

@Test
public void testCaching1() throws Exception {
    String testFolder = "d:/workspace/java/e-gov/eGovFramework/RTE/DEV/trunk/Foundation/egovframework.rte.fdl.filehandling/test";

    /*/* w w  w  .  j a  v a2  s  .c  o  m*/
     * ? Manager ?
     * CacheStrategy.MANUAL      : Deal with cached data manually. Call FileObject.refresh() to refresh the object data.
     * CacheStrategy.ON_RESOLVE : Refresh the data every time you request a file from FileSystemManager.resolveFile
     * CacheStrategy.ON_CALL   : Refresh the data every time you call a method on the fileObject. You'll use this only if you really need the latest info as this setting is a major performance loss.
