Constructor Detail

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)

Entity reference are immutable since 3.3M2, so this method is now protected. Overridden in order to verify the validity of the passed parent.

Overrides:

setParent in class EntityReference

Parameters:

parent - the parent for this entity, may be null for a root entity.

Throws:

IllegalArgumentException - if the passed parent is not a valid attachment reference parent (ie an attachment reference)

setType

protected void setType(EntityType type)

Entity reference are immutable since 3.3M2, so this method is now protected. Overridden in order to verify the validity of the passed type.

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

replaceParent

public AttachmentReference replaceParent(EntityReference oldParent,
                                         EntityReference newParent)

Description copied from class: EntityReference

Return a clone of this reference, but with one of its parent replaced by another one.

Overrides:

replaceParent in class EntityReference

Parameters:

oldParent - the old parent that will be replaced

newParent - the new parent that will replace oldParent in the chain. If the same as oldParent, this is returned.

Returns:

a new reference with a amended parent chain
