Description

Details

AccessibleHypertext_ref ()

void                AccessibleHypertext_ref             (AccessibleHypertext *obj);

Increment the reference count for an AccessibleHypertext object. Since AccessibleHypertext is derived from AccessibleText, this is the same as AccessibleText_unref().

obj :

 a pointer to the AccessibleHypertext object on which to operate.

AccessibleHypertext_unref ()

void                AccessibleHypertext_unref           (AccessibleHypertext *obj);

Decrement the reference count for an AccessibleHypertext object. Since AccessibleHypertext is derived from AccessibleText, this is the same as AccessibleText_unref().

obj :

 a pointer to the AccessibleHypertext object on which to operate.

AccessibleHypertext_getNLinks ()

long                AccessibleHypertext_getNLinks       (AccessibleHypertext *obj);

Get the total number of AccessibleHyperlinks which an AccessibleHypertext implementor has.

obj :

 a pointer to the AccessibleHypertext implementor on which to operate.

Returns :

 a long indicating the number of AccessibleHyperlinks of the AccessibleHypertext implementor, or -1 if the number cannot be determined (for example, if the AccessibleHypertext object is so large that it is not all currently in the memory cache).

AccessibleHypertext_getLink ()

AccessibleHyperlink * AccessibleHypertext_getLink       (AccessibleHypertext *obj,
                                                         long int linkIndex);

Get the AccessibleHyperlink object at a specified index.

obj :

 a pointer to the AccessibleHypertext implementor on which to operate.

linkIndex :

 a (zero-index) long integer indicating which hyperlink to query.

Returns :

 the AccessibleHyperlink object specified by linkIndex.

AccessibleHypertext_getLinkIndex ()

long                AccessibleHypertext_getLinkIndex    (AccessibleHypertext *obj,
                                                         long int characterOffset);

Get the index of the AccessibleHyperlink object at a specified character offset.

obj :

 a pointer to the AccessibleHypertext implementor on which to operate.

characterOffset :

 an integer specifying the character offset to query.

Returns :

 the linkIndex of the AccessibleHyperlink active at character offset characterOffset, or -1 if there is no hyperlink at the specified character offset.
