Overview

The <ConditionScript> element contains a script (or a reference to a script) that ultimately applies an implementation of Predicate<EntityDescriptor> to > to a given entity descriptor.

The <ConditionScript> element implicitly iterates over all entity descriptors in the metadata filtering pipeline. For each entity descriptor, the parent parent <MetadataFilter> element acts on the input entity descriptor if (and only if) the predicate evaluates to true. The action taken depends on the type of metadata filter.

...

The <ConditionScript> element is a configuration element of type ScriptType.The following sections describe the attributes and elements of the ScriptType type.

Script Context

...

Name	Type	Description
input	EntityDescriptor	The EntityDescriptor to evaluate for exclusion
customObjectRef	any	A custom object to inject into the script

Examples

The following trivial implementation of Predicate<EntityDescriptor> always > always returns false regardless of the input argument:

...

A more complex example might use the custom object to help in the definition:

<ConditionScript customObjectRef="BeanID">
    <Script>
    <![CDATA[
        "use strict";
        var someCondition = function(entityID) {
            // Good stuff
        }
        
        var result;
        // CustomObjectRef points to a <util:map> where the key is a string and the value is an 'interesting bean'
		if (someCondition(input.getEntityID())) {
            result = custom["myFirstBean"].someFunction(input);
        } else {
            result = custom["mySecondBean"].someOtherFunction(input); 
        }
        result;
    ]]>
    </Script>
</ConditionScript>
