Advanced Value Comparison Rule

An advanced value comparison rule compares the output of two value declarations defined using ACMA DL. This type of rule can evaluate complex scenarios involving multiple attributes and transforms.

As ACMA does not know in advance what the resulting type of the value declarations will be, you must define the comparison type to use in the evaluation. If the value declarations expand to a data type that does not match the value specified in the compare as parameter, an error will be raised and the operation will fail

Parameters

Group operator If the first value parameter is expanded and returns a multivalued response, the group operator is used to determine how to evaluate the rule. The group operator can specify that any, all, none, or one of the first values must match the second value provided in the rule
First value The first value to use in the comparison. This can be any valid ACMA DL string
Operator The type of comparison to perform. This is dependent on the compare as parameter
Second value The second value to use in the comparison. This can be any valid ACMA DL string
Transforms The transform chain to apply to the expanded value from the value parameters
Compare as Specifies the type of data that will be compared.

The value declarations provided will first be expanded, and then have any transformed applied, before being compared to each other.
