Filtering Messages

Help menu

Filters can be specified at various places in Blue Integrator, such as on the Receive Port Configuration Form (to determine whether to process a message) in the Forms Engine (to determine whether to display a control), or when correlating a Workflow Receive Port Message Activity.

The Blue Integrator Filter engine lets you to specify a number of conditional expressions as part of a filter. Each expression is made up of one or two operands (each a constant expression, an XPath expression to be evaluated on the document, the evaluated type (schema) of the document or a Message Context property) and an operator.  These expressions can then be configured into an AND, OR, and NOT tree using the mouse drag and drop method, or using command buttons provided on the interface.
