Constructor Detail

LinkResolver

public LinkResolver(java.lang.String id,
            Area a)

Create a new link resolver.

Parameters:

id - the id to resolve

a - the area that will have the link attribute

Method Detail

isResolved

public boolean isResolved()

Description copied from interface: Resolvable

Check if this area has been resolved.

Specified by:

isResolved in interface Resolvable

Returns:

true if this link is resolved

getIDRefs

public java.lang.String[] getIDRefs()

Get the references for this link.

Specified by:

getIDRefs in interface Resolvable

Returns:

the String array of references.

resolveIDRef

public void resolveIDRef(java.lang.String id,
                java.util.List pages)

Resolve by adding an internal link to the first PageViewport in the list. This method allows the Resolvable object to resolve one of its unresolved idrefs with the actual set of PageViewports containing the target ID. The Resolvable object initially identifies to the AreaTreeHandler which idrefs it needs resolved. After the idrefs are resolved, the ATH calls this method to allow the Resolvable object to update itself with the PageViewport information.

Specified by:

resolveIDRef in interface Resolvable

Parameters:

id - an ID matching one of the Resolvable object's unresolved idref's.

pages - the list of PageViewports with the given ID

resolveIDRef

public void resolveIDRef(java.lang.String id,
                PageViewport pv)

Resolve by adding an InternalLink trait to the area

Parameters:

id - the target id (should be equal to the object's idRef)

pv - the PageViewport containing the first area with the given id
