Processing routines for logical expressions
Classes| Class | Description of the | |
|---|---|---|
 | ArithmeticParser | A parser for arithmetic expressions (experimental). Creates an equivalent tree from a text expression. |
| BooleanParser | A parser for Boolean expressions. Creates an equivalent tree from a text expression. |
| ExpressionParser | A parser for general expressions. Creates an equivalent tree from a text expression. Must be derived; the syntax must then be defined in the derivation. BooleanParserArithmeticParserLogicalParser |
| LogicalParser | A parser for extended Boolean expressions. In addition to the parameters defined in BooleanParser Operators Operators for 'less than', 'equal to' and 'greater than' are taken into account. For reasons of convenience, operators are also used in the for 'unequal', 'less than or equal to' and 'greater than or equal to'. Creates an equivalent tree from a text expression. |
| SyntaxTree | Generic tree with parsed logical or arithmetic expression. Function: Evaluates expressions and creates suitable syntax trees. |
| TresholdParser | A parser with the ability to resolve threshold operators. Derived from the parser for extended Boolean expressions. In addition to the Operators nine operators for 10%, 20%, ... , 80%, 90% threshold value. The threshold value logic (treshold) checks whether a certain percentage of the jobs that are subordinate to a job have been cancelled. node returned the result true. If the value specified by the selected operator percentage (threshold value) is reached or exceeded, the entire job switches to true (green display). Creates an equivalent tree from a text expression. |
