public abstract class AbstractClassGenerator

extends java.lang.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.

setNamePrefix

protected void setNamePrefix(java.lang.String namePrefix)

getClassName

protected final java.lang.String getClassName()

setClassLoader

public void setClassLoader(java.lang.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.

Parameters:

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

setNamingPolicy

public void setNamingPolicy(NamingPolicy namingPolicy)

Override the default naming policy.

Parameters:

namingPolicy - the custom policy, or null to use the default

See Also:

DefaultNamingPolicy

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.

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.
