Method Detail

getMetaClass

public MetaClass getMetaClass(java.lang.Class theClass)

Specified by:

getMetaClass in interface MetaClassRegistry

removeMetaClass

public void removeMetaClass(java.lang.Class theClass)

Description copied from interface: MetaClassRegistry

Removes a cached MetaClass from the registry

Specified by:

removeMetaClass in interface MetaClassRegistry

Parameters:

theClass - The Java class of the MetaClass to remove

setMetaClass

public void setMetaClass(java.lang.Class theClass,
                MetaClass theMetaClass)

setMetaClass in interface MetaClassRegistry

Parameters:

theClass -

theMetaClass -

useAccessible

public boolean useAccessible()

getMetaClassCreationHandler

public MetaClassRegistry.MetaClassCreationHandle getMetaClassCreationHandler()

Gets a handle internally used to create MetaClass implementations WARNING: experimental code, likely to change soon

Specified by:

getMetaClassCreationHandler in interface MetaClassRegistry

Returns:

the handle

setMetaClassCreationHandle

public void setMetaClassCreationHandle(MetaClassRegistry.MetaClassCreationHandle handle)

Sets a handle internally used to create MetaClass implementations. When replacing the handle with a custom version, you should resuse the old handle to keep custom logic and to use the default logic as fallback. WARNING: experimental code, likely to change soon

Specified by:

setMetaClassCreationHandle in interface MetaClassRegistry

Parameters:

handle - the handle

getInstance

public static MetaClassRegistry getInstance(int includeExtension)

Singleton of MetaClassRegistry. Shall we use threadlocal to store the instance?

Parameters:

includeExtension -

getInstanceMethods

public FastArray getInstanceMethods()

getStaticMethods

public FastArray getStaticMethods()
