BroadleafFileServiceImpl (BroadleafCommerce 6.0.3-SNAPSHOT API)

java.lang.Object
- org.broadleafcommerce.common.file.service.BroadleafFileServiceImpl

All Implemented Interfaces:

BroadleafFileService
```
@Service(value="blFileService")
public class BroadleafFileServiceImpl
extends Object
implements BroadleafFileService
```
Many components in the Broadleaf Framework can benefit from creating and manipulating temporary files as well as storing and accessing files in a remote repository (such as AmazonS3). This service provides a pluggable way to provide those services via FileServiceProvider implementations. This service can be used by any component that needs to write files to an area shared by multiple application servers. For example usage, see SiteMapGenerator. The Broadleaf CMS module also uses this component to load, store, and manipulate images for the file-system. Generally, the process to create a new asset in the shared file system is ... 1. Call initializeWorkArea() to get a temporary directory 2. Create files, directories, etc. using the FileWorkArea.filePathLocation as the root directory. 3. Once your file processing is complete, call #addOrUpdateResources(FileWorkArea, FileApplicationType) to 4. Call #closeWorkArea() to clear out the temporary files

  - initializeWorkArea
```
public FileWorkArea initializeWorkArea()
```
    Create a file work area that can be used for further operations.
    
    Specified by:
    
    initializeWorkArea in interface BroadleafFileService
    
    Returns:
  - closeWorkArea
```
public void closeWorkArea(FileWorkArea fwArea)
```
    Closes the passed in work area. This method will delete the work area (typically a directory on the file system and all items it encloses).
    
    Specified by:
    
    closeWorkArea in interface BroadleafFileService
    
    Parameters:
    
    Work - Area
  - getResource
```
public File getResource(String name)
```
    Description copied from interface: BroadleafFileService
    
    Returns a File representing the passed in name. This method will always access the file via the FileProvider which might be a remote operation.
    
    Specified by:
    
    getResource in interface BroadleafFileService
    
    Parameters:
    
    name - - fully qualified path to the resource
    
    Returns:
  - getLocalResource
```
protected File getLocalResource(String resourceName,
                                boolean skipSite)
```
  - getLocalResource
```
public File getLocalResource(String resourceName)
```
    Description copied from interface: BroadleafFileService
    
    Checks for a resource in the temporary directory of the file-system. Will check for a site-specific file.
    
    Specified by:
    
    getLocalResource in interface BroadleafFileService
    
    Returns:
  - getSharedLocalResource
```
public File getSharedLocalResource(String resourceName)
```
    Description copied from interface: BroadleafFileService
    
    Checks for a resource in the temporary directory of the file-system. Will check for a global (e.g. not site specific file).
    
    Specified by:
    
    getSharedLocalResource in interface BroadleafFileService
    
    Returns:
  - getResource
```
public File getResource(String name,
                        Long localTimeout)
```
    Description copied from interface: BroadleafFileService
    
    Returns a File representing the resource. This method first checks the local temporary directory for the file. If it exists and has been modified within the timeout parameter, it will be returned. Otherwise, this method will make a call to BroadleafFileService.getResource(String). If the timeout parameter is null then if the resource exists locally, it will be returned.
    
    Specified by:
    
    getResource in interface BroadleafFileService
    
    Parameters:
    
    name - - fully qualified path to the resource

    Description copied from interface: BroadleafFileService
    
    Allows assets to be included in the Java classpath. This method was designed to support an internal Broadleaf use case and may not have general applicability beyond that. For Broadleaf demo sites, many of the product images are shared across the demo sites. Rather than copy those images, they are stored in a Jar file and shared by all of the sites.
