All Implemented Interfaces:
org.codehaus.groovy.ast.GroovyClassVisitor, org.codehaus.groovy.ast.GroovyCodeVisitor, org.codehaus.groovy.transform.ErrorCollecting
public final class SandboxChecker extends org.codehaus.groovy.ast.ClassCodeVisitorSupport
Compile-time sandbox checks, run in two passes:
  • preResolve() at CONVERSION: imports, annotations (@Grab, @ASTTest) and member names, before names are resolved and before most AST transforms run
  • postResolve() at CANONICALIZATION: resolved types (constructors, casts, declarations, class literals, receivers)
Violations are reported as compilation errors with line numbers.

This layer is best-effort: Groovy is dynamic, so receivers are unknown and names can be computed at runtime. Computed member names are rejected outright. The class loader filter is the actual boundary; this layer closes the cheap paths and gives readable errors.
