Interface BroadleafFileService

All Known Implementing Classes:

BroadleafFileServiceImpl

public interface 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.

Method Detail

initializeWorkArea

FileWorkArea initializeWorkArea()

Create a file work area that can be used for further operations.

Returns:

closeWorkArea

void closeWorkArea(FileWorkArea workArea)

Closes the passed in work area. This method will delete all items contained in the work area. Future calls using this WorkArea will cause a RuntimeError

Parameters:

Work - Area

getResource

File getResource(String name)

Returns a File representing the passed in name. This method will always access the file via the FileProvider which might be a remote operation.

Parameters:

name - - fully qualified path to the resource

Returns:

getResource

File getResource(String name,
               Long timeout)

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 getResource(String). If the timeout parameter is null then if the resource exists locally, it will be returned.

Parameters:

name - - fully qualified path to the resource

timeout - - timeframe that the temporary file is considered valid

Returns:

getLocalResource

File getLocalResource(String fullUrl)

Checks for a resource in the temporary directory of the file-system. Will check for a site-specific file.

Parameters:

fullUrl -

Returns:

getSharedLocalResource

File getSharedLocalResource(String fullUrl)

Checks for a resource in the temporary directory of the file-system. Will check for a global (e.g. not site specific file).

Parameters:

fullUrl -

Returns:

checkForResourceOnClassPath

boolean checkForResourceOnClassPath(String name)

Returns true if the resource is available on the classpath.

Parameters:

name -

Returns:

getClasspathResource

InputStream getClasspathResource(String name)

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.

Parameters:

name - - fully qualified path to the resource

Returns:

removeResource

boolean removeResource(String name)

Removes the resource from the configured FileProvider

Parameters:

name - - fully qualified path to the resource

applicationType - - The type of file being accessed

addOrUpdateResource

@Deprecated
void addOrUpdateResource(FileWorkArea workArea,
                                  File file,
                                  boolean removeFilesFromWorkArea)

Deprecated. use addOrUpdateResourceForPath(FileWorkArea, File, boolean)

Takes in a temporary work area and a single File and copies that files to the configured FileProvider's permanent storage.

Passing in removeFilesFromWorkArea to true allows for more efficient file processing when using a local file system as it performs a move operation instead of a copy.

Parameters:

workArea -

fileName -

removeFilesFromWorkArea -

addOrUpdateResourceForPath

String addOrUpdateResourceForPath(FileWorkArea workArea,
                                File file,
                                boolean removeFilesFromWorkArea)

Takes in a temporary work area and a single File and copies that files to the configured FileProvider's permanent storage.

Passing in removeFilesFromWorkArea to true allows for more efficient file processing when using a local file system as it performs a move operation instead of a copy.

Parameters:

workArea - the work area from the given file

file - the file to upload

removeFilesFromWorkArea - whether or not the given file should be removed from workArea when it has been copied

addOrUpdateResources
