/**
|
|
* SECTION:atkhyperlinkimpl
|
|
* @Short_description: An interface from which the AtkHyperlink
|
|
* associated with an AtkObject may be obtained.
|
|
* @Title:AtkHyperlinImpl
|
|
*
|
|
* AtkHyperlinkImpl allows AtkObjects to refer to their associated
|
|
* AtkHyperlink instance, if one exists. AtkHyperlinkImpl differs
|
|
* from AtkHyperlink in that AtkHyperlinkImpl is an interface, whereas
|
|
* AtkHyperlink is a object type. The AtkHyperlinkImpl interface
|
|
* allows a client to query an AtkObject for the availability of an
|
|
* associated AtkHyperlink instance, and obtain that instance. It is
|
|
* thus particularly useful in cases where embedded content or inline
|
|
* content within a text object is present, since the embedding text
|
|
* object implements AtkHypertext and the inline/embedded objects are
|
|
* exposed as children which implement AtkHyperlinkImpl, in addition
|
|
* to their being obtainable via AtkHypertext:getLink followed by
|
|
* AtkHyperlink:getObject.
|
|
*
|
|
* The AtkHyperlinkImpl interface should be supported by objects
|
|
* exposed within the hierarchy as children of an AtkHypertext
|
|
* container which correspond to "links" or embedded content within
|
|
* the text. HTML anchors are not, for instance, normally exposed
|
|
* this way, but embedded images and components which appear inline in
|
|
* the content of a text object are. The AtkHyperlinkIface interface
|
|
* allows a means of determining which children are hyperlinks in this
|
|
* sense of the word, and for obtaining their corresponding
|
|
* AtkHyperlink object, from which the embedding range, URI, etc. can
|
|
* be obtained.
|
|
*
|
|
* To some extent this interface exists because, for historical
|
|
* reasons, AtkHyperlink was defined as an object type, not an
|
|
* interface. Thus, in order to interact with AtkObjects via
|
|
* AtkHyperlink semantics, a new interface was required.
