Filtering Question

Hi

is there a way to set up a filter (e.g. attribute_value_filter in ExampleFilter) such that the attributes are filtered relative to a variable as opposed to a fixed value?

thx

Hi,
yes. I think that should to the Attribute_filter, isn't it?

Greetings,

thx, Sebastian, could you post an example?

i know how to filter, say for attribute1 to be greater than zero (e.g. att1>0), but how can i filter for attribute1 to be greater than a variable (e.g. att1>x) where i would specify x externally. or ultimately get ParameterOptimisation to choose it for me.

G'Day,

Variables are called Macros in RM, and can be incorporated most places that text gets accepted, like in SQL or parameters, in the format %{Macro_name} , like this...

<operator name="Root" class="Process" expanded="yes">
    <operator name="ExampleSetGenerator" class="ExampleSetGenerator">
        <parameter key="target_function"	value="random"/>
    </operator>
    <operator name="Set Your Variable X" class="SingleMacroDefinition">
        <parameter key="macro"	value="X"/>
        <parameter key="value"	value="0.5"/>
    </operator>
    <operator name="ExampleFilter" class="ExampleFilter">
        <parameter key="condition_class"	value="attribute_value_filter"/>
        <parameter key="parameter_string"	value="att1&lt;%{X}"/>
    </operator>
</operator>

thank you very much. very helpful as always.

is there anywhere a list of acceptable synthax options for parameter_string (such as "att1<%{X}")?
