Expression condition.
Expression condition operation.
|
explicitprotected |
Creates an expression condition that can be attached to triggers.
Expression condition compares two operands with a specified comparison operator. Operand can be either a fixed value, a message argument from the message that the trigger forwards to the condition, or a property value that is read from an object specified by a relative path to the trigger object. Both operands and the operation must be set before the condition can be used.

void kanzi::ExpressionCondition::setOperation | ( | Operation | operation | ) |
Sets the comparisons operation for the condition.
Not all property types support all operations. If the operation is not supported, the condition evaluates to KZ_FALSE.
Sets an operand in the comparison to be read from a fixed value.
kzsError kanzi::ExpressionCondition::setOperandMessageArgument | ( | Operand | operand, |
const KzuPropertyType * | messageArgument, | ||
PropertyField | argumentField | ||
) |
Sets an operand in the comparison to be read from the forwarded message from the trigger.
kzsError kanzi::ExpressionCondition::setOperandProperty | ( | Operand | operand, |
kzString | objectPath, | ||
const KzuPropertyType * | propertyType, | ||
PropertyField | propertyField | ||
) |
Sets an operand in the comparison to be read from an objects property.
