public class CpsTransformer
extends org.codehaus.groovy.control.customizers.CompilationCustomizer
implements org.codehaus.groovy.ast.GroovyCodeVisitor

Performs CPS transformation of Groovy methods.

Every method not annotated with NonCPS gets rewritten. The general strategy of CPS transformation is as follows:

Before:

 Object foo(int x, int y) {
   return x+y;
 }
 

After:

 Object foo(int x, int y) {
   // the first part is AST of the method body
   // the rest (including implicit receiver argument) is actual value of arguments
   throw new CpsCallableInvocation(___cps___N, this, new Object[] {x, y});
 }

 private static CpsFunction ___cps___N = ___cps___N();

 private static final CpsFunction ___cps___N() {
   Builder b = new Builder(...);
   return new CpsFunction(['x','y'], b.plus(b.localVariable("x"), b.localVariable("y"))
 }
 

That is, we transform a Groovy AST of the method body into a tree of Blocks by using Builder, then the method just returns this function object and expect the caller to evaluate it, instead of executing the method synchronously before it returns.

This class achieves this transformation by implementing GroovyCodeVisitor and traverse Groovy AST tree in the in-order. As we traverse this tree, we produce another Groovy AST tree that invokes Builder. Note that we aren't calling Builder directly here; that's supposed to happen when the Groovy code under transformation actually runs.

Groovy AST that calls Builder is a tree of function call, so we build MethodCallExpressions in the top-down manner. We do this by makeNode(String, Runnable), which creates a call to Builder.xxx(...), then supply the closure that fills in the arguments to this call by walking down the original Groovy AST tree. This walk-down is done by calling visit(ASTNode) (to recursively visit ASTs), or by calling literal(String) methods, which generate string/class/etc literals, as sometimes Builder methods need them as well.

processConstructors

Constructors can't be transformed - if we throw a CpsCallableInvocation from inside a constructor, there's no way to get back to the continuation. The object does not get created and so we're unable to proceed with it. The same thing applies for object initializers.

shouldBeTransformed

protected boolean shouldBeTransformed(org.codehaus.groovy.ast.MethodNode node)

Should this method be transformed?

visitMethod

public void visitMethod(org.codehaus.groovy.ast.MethodNode m)

Transforms asynchronous workflow method. From: ReturnT foo( T1 arg1, T2 arg2, ...) { ... body ... } To: private static CpsFunction ___cps___N = ___cps___N(); private static final CpsFunction ___cps___N() { return new CpsFunction(['arg1','arg2','arg3',...], CPS-transformed-method-body) } ReturnT foo( T1 arg1, T2 arg2, ...) { throw new CpsCallableInvocation(___cps___N, this, new Object[] {arg1, arg2, ...}) }

makeBuilder

protected org.codehaus.groovy.ast.expr.Expression makeBuilder(org.codehaus.groovy.ast.MethodNode m)

Generates code that instantiates a new Builder.

Hook for subtypes to tweak builder, for example to Builder.contextualize(com.cloudbees.groovy.cps.sandbox.CallSiteTag...)

 Builder b = new Builder(new MethodLocation(...));
 b.withClosureType(...);
 

Parameters:

m - Method being transformed.

getTrustTag

protected Class getTrustTag()
