Expressions in LinkCriteria
Expressions in Link Criteria provide a similar list of pre-defined objects. Again, note that you also have access to any other objects or variables currently defined in the AssemblyLine’s script engine.
| Object | Significance |
|---|---|
| config | The component’s Interface configuration object |
| mc | The MetamergeConfig object of the Config instance (config.getMetamergeConfig()) |
| work | The Work entry of the AssemblyLine |
| task | The component itself, or a named component |
| alcomponent | The Connector or Function Component |
Table 1. Pre-defined objects for use in Expressions in LinkCriteria
So, for example, let’s say that you want to set up the Link Criteria for a Connector so that the Attribute to use in the match is determined at run time. In addition to standard data Attributes in the Work entry, there is also a matchAtt Attribute with the string value “uid”. In this case, the following Expression used in Link Criteria:
{work.matchAtt} EQUALS {work.uid}
is equivalent to this:
uid EQUALS $uid
