org.codehaus.groovy.reflection.ClassInfo

All Implemented Interfaces:: Finalizable

public class ClassInfo
extends Object
implements Finalizable

Handle for all information we want to keep about the class

This class handles caching internally and its advisable to not store references directly to objects of this class. The static factory method getClassInfo(Class) should be used to retrieve an instance from the cache. Internally the Class associated with a ClassInfo instance is kept as WeakReference, so it not safe to reference and instance without the Class being either strongly or softly reachable.

Method Details
- getVersion
  
  public int getVersion()
- incVersion
  
  public void incVersion()
- getModifiedExpando
  
  public ExpandoMetaClass getModifiedExpando()
- clearModifiedExpandos
  
  public static void clearModifiedExpandos()
- getTheClass
  
  public final Class<?> getTheClass()
  
  Returns the Class associated with this ClassInfo.
  This method can return null if the Class is no longer reachable through any strong or soft references. A non-null return value indicates that this ClassInfo is valid.
  
  Returns:
  
  the Class associated with this ClassInfo, else null
- getCachedClass
  
  public CachedClass getCachedClass()
- getArtifactClassLoader
  
  public ClassLoaderForClassArtifacts getArtifactClassLoader()
- getClassInfo
  
  public static ClassInfo getClassInfo(Class cls)
- remove
  
  public static void remove(Class<?> cls)
  
  Removes a ClassInfo from the cache. This is useful in cases where the Class is parsed from a script, such as when using GroovyClassLoader#parseClass, and is executed for its result but the Class is not retained or cached. Removing the ClassInfo associated with the Class will make the Class and its ClassLoader eligible for garbage collection sooner that it would otherwise.
  
  Parameters:
  
  cls - the Class associated with the ClassInfo to remove from cache
- getAllClassInfo
  
  public static Collection<ClassInfo> getAllClassInfo()
- onAllClassInfo
  
  public static void onAllClassInfo(ClassInfo.ClassInfoAction action)
- getStrongMetaClass
  
  public MetaClass getStrongMetaClass()
- setStrongMetaClass
  
  public void setStrongMetaClass(MetaClass answer)
- getWeakMetaClass
  
  public MetaClass getWeakMetaClass()
- setWeakMetaClass
  
  public void setWeakMetaClass(MetaClass answer)
- getMetaClassForClass
  
  public MetaClass getMetaClassForClass()
- getMetaClass
  
  public final MetaClass getMetaClass()
  
  Returns the MetaClass for the Class associated with this ClassInfo. If no MetaClass exists one will be created.
  It is not safe to call this method without a Class associated with this ClassInfo. It is advisable to aways retrieve a ClassInfo instance from the cache by using the static factory method getClassInfo(Class) to ensure the referenced Class is strongly reachable.
  
  Returns:
  
  a MetaClass instance
- getMetaClass
