We don't want to create the rule until we need it and are ready to use it. In addition, the creation of an AT-SPI match rule requires you specify quite a few things (see the __init__), most of which are irrelevant to the search at hand. This class makes it possible for the StructuralNavigationObject creator to just specify the few criteria that actually matter. NFc C sx || _ |p|j| _|| _|p|j| _|| _|p|j| _|| _| p"|j| _ | | _ | | _ t � � | _|D ]} | j�| � q1dS )a� Creates a new match criteria object. Arguments: - collection: the collection interface for the document in which the accessible objects can be found. - states: a list of pyatspi states of interest - matchStates: whether an object must have all of the states in the states list, any of the states in the list, or none of the states in the list. Must be one of the collection interface MatchTypes if provided. - objAttrs: a list of object attributes (not text attributes) - matchObjAttrs: whether an object must have all of the attributes in the objAttrs list, any of the attributes in the list, or none of the attributes in the list. Must be one of the collection interface MatchTypes if provided. - interfaces: (We aren't using this. According to the at-spi idl, it is a string.) - matchInterfaces: The collection MatchType for matching by interface. - invert: If true the match rule will find objects that don't match. We always use False. - applyPredicate: whether or not a predicate should be applied as an additional check to see if an item is indeed a match. This is necessary, for instance, when one of the things we care about is a text attribute, something the collection interface doesn't include in its criteria.

These characteristics may be something as simple as a role and/or a state of interest. Or they may be something more complex such as character counts, text attributes, and other object attributes. c C sL || _ || _|| _|| _|| _|| _|| _i | _t� � | _ g | _ | � � dS )a Creates a new structural navigation object. Arguments: - structuralNavigation: the StructuralNavigation class associated with this object. - objType: the type (e.g. BLOCKQUOTE) associated with this object. - bindings: a dictionary of all of the possible bindings for this object. In the case of all but the "atLevel" bindings, each binding takes the form of [keysymstring, modifiers, description]. The goPreviousAtLevel and goNextAtLevel bindings are each a list of bindings in that form. - predicate: the predicate to use to determine if a given accessible matches this structural navigation object. Used when a search via collection is not possible or practical. - criteria: a method which returns a MatchCriteria object which can in turn be used to locate the next/previous matching accessible via collection. - presentation: the method which should be called after performing the search for the structural navigation object. - dialogData: the method which returns the title, column headers, and row data which should be included in the "list of" dialog for the structural navigation object.

Arguments: - structuralNavigationObject: the StructuralNavigationObject which represents the table cell. - thisCell: the pyatspi accessible TABLE_CELL we're currently in - currentCoordinates: the [row, column] of thisCell. Note, we cannot just get the coordinates because in table cells which span multiple rows and/or columns, the value returned by table.getRowAtIndex() is the first row the cell spans. Likewise, the value returned by table.getColumnAtIndex() is the left-most column. Therefore, we keep track of the row and column from our perspective to ensure we stay in the correct row and column. - desiredCoordinates: the [row, column] where we think we'd like to be.
