@Extension
public interface FilterVisitor

Visitor with visit methods to be called by Filter.accept(...).

Consider: It is unclear if this visitor should be applied directly to Filter, or should be walked accross the data structure by hand. The standard complient structure is well defined, and this should negate the need for a formal visitor (we don't have internal structure we are hiding).

There is still a very valid use for FilterVisitor, a instance may implement both FilterVisitor and ExpressionVisitor and ExpressionVisitory in one direction, and a FilterVisitor and a StyleVisitor in the other. The ability to directly focus on transforming data within a larger structure is something a normal data walk can not accomplish in a scalable manner.

Method Detail

visitNullFilter

Object visitNullFilter(Object extraData)

Used to account for a null filter value.

This is particularly used during data structure transofrmations, however the use of null is not recommended. Please make use of Filter.NONE and Filter.ALL as placeholder objects that communicate intent.

Parameters:

extraData - Value object provided to visitor

Returns:

subclass defined

visit

Object visit(ExcludeFilter filter,
             Object extraData)

Visit Filter.EXCLUDE (often used during data structure transformations).

Parameters:

filter - Filter.EXCLUDE.

extraData - Value object provided to visitor

Returns:

subclass supplied

visit

Object visit(IncludeFilter filter,
             Object extraData)

Visit Filter.INCLUDE (often used during data structure transformations).

Parameters:

filter - Filter.INCLUDE.

extraData - Value object provided to visitor

Returns:

subclass supplied
