ERAttachment

public ERAttachment()

Method Detail

didInsert

public void didInsert()

Description copied from interface: ERXEnterpriseObject

Called on the object after is has successfully been inserted into the database.

Specified by:

didInsert in interface ERXEnterpriseObject

Overrides:

didInsert in class ERXGenericRecord

fileName

public String fileName()

Returns the file name portion of the webPath.

Returns:

the file name portion of the webPath

erMimeType

public ERMimeType erMimeType()

Returns the ERMimeType that corresponds to the mimeType.

Returns:

the ERMimeType that corresponds to the mimeType

extension

public String extension()

Returns the file extension of this attachment, first checking the mime type, then returning the actual extension.

Returns:

the file extension of this attachment

fetchRequiredAttachmentWithWebPath

public static ERAttachment fetchRequiredAttachmentWithWebPath(EOEditingContext editingContext,
                                                              String webPath)

Fetches the required attachment associated with the given web path.

Parameters:

editingContext - the editing context to load in

webPath - the web path of the attachment

Returns:

the attachment

Throws:

NoSuchElementException - if there is no attachment with the given web path

didDelete

public void didDelete(EOEditingContext ec)

Description copied from interface: ERXEnterpriseObject

Called on the object after is has been deleted. The editing context is passed to the object since by this point the editingContext of the object is null. You should check if the ec is a child context when doing something here that can't be undone.

Specified by:

didDelete in interface ERXEnterpriseObject

Overrides:

didDelete in class ERXGenericRecord

Parameters:

ec - editing context that used to be associated with the object.
