- All Implemented Interfaces:
- java.io.Serializable, IClassLoader, IInstance, IObject
public class ClassLoaderImpl
- extends InstanceImpl
- implements IClassLoader
Implementation of a Java object representing a java.lang.ClassLoader object.
As well as standard object information it contains information about the class loader
and summary details about classes loaded by this class loader.

ClassLoaderImpl
public ClassLoaderImpl(int objectId,
long address,
ClassImpl clazz,
java.util.List<Field> fields)
- Constructs a class loader object.
- Parameters:
objectId
- the object idaddress
- the actual address of the objectclazz
- its typefields
- the fields of the object
getClassSpecificName
public java.lang.String getClassSpecificName()
- Description copied from interface:
IObject
- Get class specific name of this object which depends on the availability
of the appropriate name resolver, e.g. for a String the value of the
char[].
- Specified by:
getClassSpecificName
in interface IObject
- Overrides:
getClassSpecificName
in class AbstractObjectImpl
- Returns:
- class specific name of the given snapshot object or null if it
can't be resolved
getDefinedClasses
public java.util.List<IClass> getDefinedClasses()
throws SnapshotException
- Description copied from interface:
IClassLoader
- Returns the classes defined by this class loader instance.
- Specified by:
getDefinedClasses
in interface IClassLoader
- Throws:
SnapshotException
getRetainedHeapSizeOfObjects
public long getRetainedHeapSizeOfObjects(boolean calculateIfNotAvailable,
boolean calculateMinRetainedSize,
IProgressListener listener)
throws SnapshotException
- Description copied from interface:
IClassLoader
- Returns the retained size of all objects and classes loaded by this class
loader.
- Specified by:
getRetainedHeapSizeOfObjects
in interface IClassLoader
- Parameters:
calculateIfNotAvailable
- if false only return a cached version of the sizecalculateMinRetainedSize
- if true then when calculating use an approximationlistener
- to indicate progress and errors
- Returns:
- the retained size, negative if approximate
- Throws:
SnapshotException
doGetDefinedClasses
public static final java.util.List<IClass> doGetDefinedClasses(ISnapshot dump,
int classLoaderId)
throws SnapshotException
- Gets the classes defined by a given loader
- Parameters:
dump
- the snapshotclassLoaderId
- the class loader to look for
- Returns:
- a list of classes
- Throws:
SnapshotException
doGetRetainedHeapSizeOfObjects
public static final long doGetRetainedHeapSizeOfObjects(ISnapshot dump,
int classLoaderId,
boolean calculateIfNotAvailable,
boolean calculateMinRetainedSize,
IProgressListener listener)
throws SnapshotException
- Calculates the retained size of all classes and instances of the class loaded
by a class loader.
- Parameters:
dump
- the snapshotclassLoaderId
- the class loader ifcalculateIfNotAvailable
- true if to skip calculations if not already donecalculateMinRetainedSize
- true if to make an approximate calculationlistener
- to indicate progress, errors and to cancel
- Returns:
- the size, negative if approximate
- Throws:
SnapshotException
