With theANDoperator, both values must be True to result in True; otherwise, the value is False. With theXOR(Exclusive OR) operator, only one value can be True to result in True; otherwise, the value is False. The following example puts all the operators together. Boolean expressions When ...
expression are strongly typed at compile time. When the compiler can infer the types of input parameters, like in the preceding example, you can omit type declarations. If you need to specify the type of input parameters, you must do that for each parameter, as the following example shows:...
Choose a runtime expression if you're working withconditionsandexpressions. However, don't use a runtime expression if you don't want your empty variable to print (example:$[variables.var]). For example, if you have conditional logic that relies on a variable having a specific value or no...
For example, you can design an Eval Expression field that uses the values of two auto-extracted fields. Extracted fields precede calculated fields, so in this case the fields would be processed in the correct order without any work on your part. But you might also use the eval expression fi...
Example: String Equality The following expression selects instances with the specified instance type. attribute:ecs.instance-type== t2.small Example: Argument List The following expression selects instances in the us-east-1a or us-east-1b Availability Zone. ...
For example, if your lookup configuration hasfilter = (CustID>500) AND (CustName="P*"), it tries to retrieve values only from those records in the KV Store collection that have aCustIDvalue that greater than 500 and aCustNamevalue that begins with the letter P. ...
The value list filter can also be used for Boolean data types. For Boolean data types, this filter contains two values: true and false. These value are used inPythonfor specifying the value. The true value is the first value in the list. For an example, seeAdd Fieldand the...
* @example setEmit('foo', 0, '(evt: "change", value: string): void') * * @returns false if the definition does not exist. */ setEmit( name: string | StringLiteral, index: number, signature: string ): boolean /** * Removes specified emit from TS interface. `definitions` will up...
For example, suppose you want to designate the workspace variablemyDataTypeas an alias for asingledata type to use as an expression in theTypeproperty of anMATLAB Functionblock input variable. Create an instance of theSimulink.AliasTypeclass and set itsBaseTypeproperty by entering these commands:...
Condition is a Boolean expression that determines whether the transition occurs. If you do not specify a condition, the transition occurs one time step after the source state becomes active. ConditionAction is an instruction that executes when the condition that guards the transition is true. The ...
