Tags
As Telosys aims to provide highly customizable models (and predefined annotations are usually not sufficient to handle all special cases) in version 3.3.0 "tags" have been added for attributes and since version 4.0.0 they can be used everywhere (entity, attribute and link).
Tags are a very simple way to easily customize your models by adding as much additional information as you want.
Set tags in model
Each entity, attribute or link can have 0 to N tags.
Like annotations, tags provide additional information usable during the code generation. But, unlike annotations, tags do not have predefined names. The user can define as many tags as he wants.
A tag is any name starting with "#" and optionally having a value. If the tag has a value then the value is defined between "(" and ")".
Examples of tags :
Use tags in templates
In a template you can define conditions based on the presence (or absence) of a tag and you can retrieve the value of a tag (with default value if necessary).
To do this, use the following syntax:
$x.hasTag("tagName")
$x.tagValue("tagName")
$x.tagValue("tagName", "defaultValue")
$x.tagValueAsBoolean("tagName", true/false)
$x.tagValueAsInt("tagName", 123)
Example : check tag presence and use its value if present
