[Java] Class SecureASTCustomizer.SecuringCodeVisitor

  • org.codehaus.groovy.control.customizers.SecureASTCustomizer.SecuringCodeVisitor
All Implemented Interfaces and Traits:
GroovyCodeVisitor
protected class SecureASTCustomizer.SecuringCodeVisitor

This visitor directly implements the GroovyCodeVisitor interface instead of using the CodeVisitorSupport class to make sure that future features of the language gets managed by this visitor. Thus, adding a new feature would result in a compilation error if this visitor is not updated.
