Constructor Details

ObjectArrayImpl

public ObjectArrayImpl(int objectId,
 long address,
 ClassImpl classInstance,
 int length)

Constructs an array of objects.

Parameters:

objectId - the object id of the array

address - the actual address

classInstance - the type of the array

length - the length of the array in elements

Method Details

getUsedHeapSize

public long getUsedHeapSize()

Description copied from interface: IObject

Get used heap size of just this object.

Specified by:

getUsedHeapSize in interface IObject

Specified by:

getUsedHeapSize in class AbstractObjectImpl

Returns:

used heap size of this object

doGetUsedHeapSize

public static long doGetUsedHeapSize(ClassImpl clazz,
 int length)

Calculates the size of an object array

Parameters:

clazz - the type

length - the length in elements

Returns:

the size in bytes

Since:

1.0

getReferenceArray

public long[] getReferenceArray()

Description copied from interface: IObjectArray

Get an array with the object addresses. 0 indicates null values in the array.

Specified by:

getReferenceArray in interface IObjectArray

Returns:

the addresses of the objects held in the array, in index order

getReferenceArray

public long[] getReferenceArray(int offset,
 int length)

Description copied from interface: IObjectArray

Get an array with the object addresses, beginning at offset and length number of elements.

Specified by:

getReferenceArray in interface IObjectArray

Parameters:

offset - where to start

length - how many entries to return

Returns:

the addresses of the objects held in the array, in index order from the index starting at offset, with length entries

getReferences

public ArrayLong getReferences()

Description copied from class: AbstractObjectImpl

Gets the outbound references from this object, as addresses.

Specified by:

getReferences in class AbstractObjectImpl

Returns:

a list of outbound references

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
