Mapping Priorities
Last modified: 14 September 2021Mapping Priorities
Mapping priorities are a set of mapping priority rules specifying an order of priority between sets of generator rules (mapping configurations).
Mapping priorities are specified in generator module property dialog. See also: Generator
Each mapping priority rule consists of left part, right part and priority symbol in the middle.
For instance:
* < [sample.language/generator: *]Left part of priority rule can only refer to mapping configurations in this generator.
Notation | Refers to |
|---|---|
* | All mappings in this generator |
modelName . * | All mappings in model |
modelName . mappingName | Mapping configuration |
{... } | Set of mappings. An entry can be either modelName . * or modelName . mappingName |
Right part of priority rule can refer to mapping configurations in this generator as well as other generators visible in scope (see Generator).
Notation | Refers to |
|---|---|
* | All mappings in this generator |
modelName . * | All mappings in model |
modelName . mappingName | Mapping configuration |
{... } | Set of mappings. An entry can be either modelName . * or modelName . mappingName |
[ languageName / generatorName : * ] | All mapping in external generator |
[ languageName / generatorName : modelName ] | All mapping in external generator model |
[ languageName / generatorName : modelName . mappingName ] | External mapping configuration |
[ languageName / generatorName : {... }] | All mapping in external generator |
[*:*] | All possible mappings |
Priority symbol
Notation | Description |
|---|---|
< | Mappings in left part are processed before mappings in right part |
<= | Mappings in left part are processed not later than mappings in right part |
== | Mappings in left part and right part are processed together |
