public abstract class AbstractClassGenerator<T> extends Object implements ClassGenerator
Abstract class for all code-generating CGLIB utilities. In addition to caching generated classes for performance, it provides hooks for customizing the ClassLoader, name of the generated class, and transformations applied before generation.

  • Method Details

    • wrapCachedClass

      protected T wrapCachedClass(Class klass)
    • unwrapCachedValue

      protected Object unwrapCachedValue(T cached)
    • setNamePrefix

      protected void setNamePrefix(String namePrefix)
    • getClassName

      protected final String getClassName()
    • setClassLoader

      public void setClassLoader(ClassLoader classLoader)
      Set the ClassLoader in which the class will be generated. Concrete subclasses of AbstractClassGenerator (such as Enhancer) will try to choose an appropriate default if this is unset.

      Classes are cached per-ClassLoader using a WeakHashMap, to allow the generated classes to be removed when the associated loader is garbage collected.

      classLoader - the loader to generate the new class with, or null to use the default
    • setContextClass

      public void setContextClass(Class contextClass)
    • setNamingPolicy

      public void setNamingPolicy(NamingPolicy namingPolicy)
      Override the default naming policy.
      namingPolicy - the custom policy, or null to use the default

    • getNamingPolicy

      public NamingPolicy getNamingPolicy()
      See Also:
    • setUseCache

      public void setUseCache(boolean useCache)
      Whether use and update the static cache of generated classes for a class with the same properties. Default is true.
    • getUseCache

      public boolean getUseCache()
      See Also:
    • setAttemptLoad

      public void setAttemptLoad(boolean attemptLoad)
      If set, CGLIB will attempt to load classes from the specified ClassLoader before generating them. Because generated class names are not guaranteed to be unique, the default is false.
    • getAttemptLoad

      public boolean getAttemptLoad()
    • setStrategy

      public void setStrategy(GeneratorStrategy strategy)
      Set the strategy to use to create the bytecode from this generator. By default an instance of DefaultGeneratorStrategy is used.
    • getStrategy

      public GeneratorStrategy getStrategy()
      See Also:
    • getCurrent

      public static AbstractClassGenerator getCurrent()
      Used internally by CGLIB. Returns the AbstractClassGenerator that is being used to generate a class in the current thread.
    • getClassLoader

      public ClassLoader getClassLoader()
    • getDefaultClassLoader

      protected abstract ClassLoader getDefaultClassLoader()
    • getProtectionDomain

      protected ProtectionDomain getProtectionDomain()
      Returns the protection domain to use when defining the class.

      Default implementation returns null for using a default protection domain. Sub-classes may override to use a more specific protection domain.
