 org.springframework.instrument.classloading.WeavingTransformer
| WeavingTransformer | | public class WeavingTransformer (Code) | | ClassFileTransformer-based weaver, allowing for a list of transformers to be
applied on a class byte array. Normally used inside class loaders.
Note: This class is deliberately implemented for minimal external dependencies,
since it is included in weaver jars (to be deployed into application servers).

| Method Summary | |
| public void | addTransformer(ClassFileTransformer transformer)
Add a class file transformer to be applied by this weaver. | | protected ClassLoader | getDefaultClassLoader()
See ClassUtils. | | public byte[] | transformIfNecessary(String className, byte[] bytes)
Apply transformation on a given class byte definition.
The method will always return a non-null byte array (if no transformation has taken place
the array content will be identical to the original one).
Parameters:
className - the full qualified name of the class in dot format (i.e. | | public byte[] | transformIfNecessary(String className, String internalName, byte[] bytes, ProtectionDomain pd)
Apply transformation on a given class byte definition.
The method will always return a non-null byte array (if no transformation has taken place
the array content will be identical to the original one).
Parameters:
className - the full qualified name of the class in dot format (i.e. |
| WeavingTransformer | | public WeavingTransformer()(Code) | | Create a new WeavingTransformer for the current context class loader.
|
| WeavingTransformer | | public WeavingTransformer(ClassLoader classLoader)(Code) | | Create a new WeavingTransformer for the given class loader.
Parameters:
classLoader - the ClassLoader to build a transformer for |
| addTransformer | | public void addTransformer(ClassFileTransformer transformer)(Code) | | Add a class file transformer to be applied by this weaver.
Parameters:
transformer - the class file transformer to register |
| transformIfNecessary | | public byte[] transformIfNecessary(String className, byte[] bytes)(Code) | | Apply transformation on a given class byte definition.
The method will always return a non-null byte array (if no transformation has taken place
the array content will be identical to the original one).
Parameters:
className - the full qualified name of the class in dot format (i.e. some.package.SomeClass)
Parameters:
bytes - class byte definition (possibly transformed) class byte definition |
| transformIfNecessary | | public byte[] transformIfNecessary(String className, String internalName, byte[] bytes, ProtectionDomain pd)(Code) | | Apply transformation on a given class byte definition.
The method will always return a non-null byte array (if no transformation has taken place
the array content will be identical to the original one).
Parameters:
className - the full qualified name of the class in dot format (i.e. some.package.SomeClass)
Parameters:
internalName - class name internal name in / format (i.e. some/package/SomeClass)
Parameters:
bytes - class byte definition
Parameters:
pd - protection domain to be used (can be null) (possibly transformed) class byte definition |
