Constructor Detail

EntryObject

public EntryObject(IObject self,
                   IObject key,
                   IObject value)

Method Detail

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

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

getSnapshot

public ISnapshot getSnapshot()

Description copied from interface: IObject

Returns the snapshot from which this object has been read.

Specified by:

getSnapshot in interface IObject

Returns:

the snapshot from which this object has been read.

setValue

public IObject setValue(IObject value)

Specified by:

setValue in interface Map.Entry<IObject,IObject>

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Specified by:

hashCode in interface Map.Entry<IObject,IObject>

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Specified by:

equals in interface Map.Entry<IObject,IObject>

Overrides:

equals in class Object
