class CompiledTagCallTransformation
extends java.lang.Object
implements org.codehaus.groovy.transform.ASTTransformation, org.codehaus.groovy.transform.TransformWithPriority

Compiles a call to a known tag into a direct invocation, wherever tags can be called from.

A tag library rewrites its own calls as it is compiled, but a controller can call tags too, and gains that ability from the TagLibraryInvoker trait rather than from being a tag library. Any class carrying that trait is therefore a candidate, which covers controllers without naming them and without a second copy of the rewriting rules. A compiled GSP calls tags as well, and reaches them through GroovyPage rather than through the trait, so it is matched separately.

Runs in a later phase than trait injection, since whether a class can call tags is only settled once its traits have been applied. Ordering by priority within a phase was not enough: it holds for transforms that declare one, but a trait arriving from a local transform is applied after every global transform has run, so a class compiled from outside the conventional directory was read before it carried the trait, and the same source read as a convention class was read after. Waiting for the phase reads every class once it is whole, which is what the rewrite needs to decide.
