Examples of org.opengis.filter.Filter.evaluate()

org.opengis.filter.Filter.evaluate()
Give an object, this method determines if the test(s) represented by this filter object are passed.
This ability is used to allow Queries against both Features and and non spatial data (such as Record) and to express constraints on permissable data values.
@param object @return true if the test(s) are passed for the provided object
