Method Detail

updateReferencesInContent

String updateReferencesInContent(String content,
                                 LinksUpdater.PartialReferenceDetails oldLinkDetails,
                                 LinksUpdater.PartialReferenceDetails newLinkDetails)

Update all the links and embedded image references in the content that referred to 'oldDetails' to now refer to 'newDetails'. It should be noted that any relative references encountered in the content will not be modified since it cannot be known whether they would be a match for the 'oldDetails' parameter. You should called expandRelativeReferencesInContent(SpaceContentEntityObject) prior to calling this method to ensure there are no relative links in the content to confuse matters.

Parameters:

content - the content to update references in

oldLinkDetails - specifies the references to be modified

newLinkDetails - specifies the reference to be used in place of those identified by 'oldDetails'.

Returns:

content with relevant references updated

updateAttachmentReferencesInContent

String updateAttachmentReferencesInContent(String content,
                                           LinksUpdater.AttachmentReferenceDetails old,
                                           LinksUpdater.AttachmentReferenceDetails updated)

Update all the attachment references in the content that referred to the 'old' attachment to now refer to the 'updated' attachment. It should be noted that any relative links encountered in the content will not be modified since it cannot be known whether they would be a match for the 'old' parameter. You should called expandRelativeReferencesInContent(SpaceContentEntityObject) prior to calling this method to ensure there are no relative attachment references in the content to confuse matters.

Parameters:

content - the content to update attachment references in

old - specifies the attachment references to be modified

updated - specifies the new attachment reference to replace the old one with

Returns:

content with specified attachment references updated.

expandRelativeReferencesInContent

String expandRelativeReferencesInContent(SpaceContentEntityObject content)

Expand any relative links or embedded images encountered in the supplied content. A relative reference is one that either has no space key (implying "current space") or one with no ResourceIdentifier at all.

This method will convert such references to an absolute reference to either it's containing space or itself (in the case of an attachment or link with no resource identifier at all).

Parameters:

content - the content to be expanded

Returns:

the body of the supplied SpaceContentEntityObject with all relative references expanded.

expandRelativeReferencesInContent

String expandRelativeReferencesInContent(Comment comment)

Expand any relative links or embedded files/images encountered in the supplied comment. A relative reference is one that either has no space key (implying "current space") or one with no ResourceIdentifier at all.

This method will convert such references to an absolute reference to either it's containing space or itself (in the case of an attachment or link with no resource identifier at all).

Parameters:

comment - the comment to be expanded

Returns:

the body of the supplied SpaceContentEntityObject with all relative references expanded.

contractAbsoluteReferencesInContent

String contractAbsoluteReferencesInContent(SpaceContentEntityObject content)

A companion method to {expandRelativeReferencesInContent(SpaceContentEntityObject) that will convert any absolute references to itself to be relative. So in a ResourceIdentifier, if a space key is present for the same space as the supplied content then this will be dropped. If the ResourceIdentifier actually refers to the SpaceContentEntityObject supplied then it will be dropped altogether.

Parameters:

content - the content to have any suitable absolute references contracted.

Returns:

the body of the supplied SpaceContentEntityObject modified as appropriate.

canonicalize

String canonicalize(String content)

Applies the same rewriter as on any of contract/expand methods.

This method is needed because even if xml structure of content is the same entity replacing by javax.xml.* and substitution done in ConfluenceXMLEventWriter will make two equal contents look different on equals method.

Returns:

canonicalized content
