Interface WebExpression
-
public interface WebExpression
The WebExpression interface represents a filter expression, which is composed of one or moreWebNode
objects. The root node of an expression can never be null, and cannot be changed by the user. The root node is generally an operator node with function type "and" or "or". However, if an expression is obtained from the server, then it does not necessarily have to be rooted at an and or or node. The expression usually exists as part ofWebPrompt
,WebElementSource
,WebFilter
, andWebTemplate
objects.- Since:
- MicroStrategy Web 7.3.1 or earlier
