    • getKey

      public IObject getKey()
      Specified by:
      getKey in interface Map.Entry<IObject,IObject>

    • getValue

      public IObject getValue()
      Specified by:
      getValue in interface Map.Entry<IObject,IObject>

    • getObjectId

      public int getObjectId()
      Description copied from interface: IObject
      Get id for the snapshot object. The id is not the address, but an internally assigned number fitting into an int (this helps reducing the memory footprint of the snapshot considerably - addresses are only used for visualization purposes).
      Specified by:
      getObjectId in interface IObject
      Returns:
      id for the snapshot object

    • getObjectAddress

      public long getObjectAddress()
      Description copied from interface: IObject
      Get address for the snapshot object. This is the address at which the object was stored in memory. Use the address only for visualization purposes and try to use the id wherever possible as the snapshot API is optimized to handle ids and not addresses. Addresses are bigger ( long), have no consecutive order (with gaps), and are not used for hashing.
      Specified by:
      getObjectAddress in interface IObject
      Returns:
      address for the snapshot object

    • getClazz

      public IClass getClazz()
      Description copied from interface: IObject
      Get class snapshot object this object is an instance of.
      Specified by:
      getClazz in interface IObject
      Returns:
      class snapshot object this object is an instance of

    • getUsedHeapSize

      public long getUsedHeapSize()
      Description copied from interface: IObject
      Get used heap size of just this object.
      Specified by:
      getUsedHeapSize in interface IObject
      Returns:
      used heap size of this object

    • getRetainedHeapSize

      public long getRetainedHeapSize()
      Description copied from interface: IObject
      Get retained heap size of this object.
      Specified by:
      getRetainedHeapSize in interface IObject
      Returns:
      retained heap size of this object (returns 0 if the dominator tree wasn't calculated for the corresponding snapshot)

    • getTechnicalName

      public String getTechnicalName()
      Description copied from interface: IObject
      Get technical name of this object which is something like class@address.
      Specified by:
      getTechnicalName in interface IObject
      Returns:
      technical name of this object which is something like class@address

    • getClassSpecificName

      public 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
      Returns:
      class specific name of the given snapshot object or null if it can't be resolved

    • getDisplayName

      public String getDisplayName()
      Description copied from interface: IObject
      Get concatenation of IObject.getTechnicalName() and IObject.getClassSpecificName().
      Specified by:
      getDisplayName in interface IObject
      Returns:
      concatenation of IObject.getTechnicalName() and IObject.getClassSpecificName()

    • getOutboundReferences

      public List<NamedReference> getOutboundReferences()
      Description copied from interface: IObject
      Get list of snapshot objects referenced from this snapshot object with the name of the field over which it was referenced.
      Specified by:
      getOutboundReferences in interface IObject
      Returns:
      list of snapshot objects referenced from this snapshot object with the name of the field over which it was referenced

    • resolveValue

      public Object resolveValue(String field) throws SnapshotException
      Description copied from interface: IObject
      Resolves and returns the value of a field specified by a dot notation. If the field is a primitive type, the value the returns the corresponding object wrapper, e.g. a java.lang.Boolean is returned for a field of type boolean. If the field is an object reference, the corresponding IObject is returned.

      The field can be specified using the dot notation, i.e. object references are followed and its fields are evaluated. If any of the object references is null, null is returned.

      Specified by:
      resolveValue in interface IObject
      Parameters:
      field - the field name in dot notation
      Returns:
      the value of the field
      Throws:
      SnapshotException - when there is a problem retrieving the field

    • getGCRootInfo

      public GCRootInfo[] getGCRootInfo() throws SnapshotException
      Description copied from interface: IObject
      Get GCRootInfo if the object is a garbage collection root or null otherwise. An object may or may not be a garbage collection root, it may even be one for multiple reasons (described in the GCRootInfo object).
      Specified by:
      getGCRootInfo in interface IObject
      Returns:
      GCRootInfo if the object is a garbage collection root or null otherwise
      Throws:
      SnapshotException - when there is a problem retrieving the information

    • getSnapshot

      public ISnapshot getSnapshot()
      Description copied from interface: IObject

      Specified by:
      getSnapshot in interface IObject
      Returns:
      the snapshot from which this object has been read.
