Constructor Details

ContentNetworkFile

protected ContentNetworkFile(NodeService nodeService,
 ContentService contentService,
 MimetypeService mimetypeService,
 NodeRef nodeRef,
 String name)

Class constructor

Parameters:

nodeService - NodeService

contentService - ContentService

mimetypeService - mimetypeService

nodeRef - NodeRef

name - String

Method Details

createFile

public static ContentNetworkFile createFile(NodeService nodeService,
 ContentService contentService,
 MimetypeService mimetypeService,
 CifsHelper cifsHelper,
 NodeRef nodeRef,
 String path,
 boolean readOnly,
 boolean attributesOnly,
 org.alfresco.jlan.server.SrvSession sess)

Helper method to create a network file given a node reference.

toString

public String toString()

Return the file details as a string

Overrides:

toString in class org.alfresco.jlan.server.filesys.NetworkFile

Returns:

String

hasContent

public final boolean hasContent()

Determine if the file content data has been opened

Returns:

boolean

openContent

public void openContent(boolean write,
 boolean trunc)
                 throws org.alfresco.jlan.server.filesys.AccessDeniedException,
org.alfresco.error.AlfrescoRuntimeException

Opens the channel for reading or writing depending on the access mode.

Side effect: sets fileSize

If the channel is already open, it is left.

Parameters:

write - true if the channel must be writable

trunc - true if the writable channel does not require the previous content data

Throws:

org.alfresco.jlan.server.filesys.AccessDeniedException - if this network file is read only

org.alfresco.error.AlfrescoRuntimeException - if this network file represents a directory
