AttachmentReference

public AttachmentReference(EntityReference reference)

Special constructor that transforms a generic entity reference into an AttachmentReference. It checks the validity of the passed reference (ie correct type and correct parent).

Parameters:

reference - the reference to be transformed

Throws:

IllegalArgumentException - if the passed reference is not a valid attachment reference

AttachmentReference

protected AttachmentReference(EntityReference reference,
                              EntityReference oldReference,
                              EntityReference newReference)

Clone an AttachmentReference, but replace one of the parent in the chain by a new one.

Parameters:

reference - the reference that is cloned

oldReference - the old parent that will be replaced

newReference - the new parent that will replace oldReference in the chain

Since:

3.3M2

AttachmentReference

public AttachmentReference(String fileName,
                           DocumentReference parent)

Create a new attachment reference based on the attachment name and the parent document reference.

Parameters:

fileName - the name of the attachment

parent - the reference of the document

Method Detail

setParent

protected void setParent(EntityReference parent)

Overrides:

setType in class EntityReference

Parameters:

type - the type for this entity

Throws:

IllegalArgumentException - if the passed type is not an attachment type

getDocumentReference

public DocumentReference getDocumentReference()

Returns:

the document reference contained in this attachment reference
