Constructor Details

AbstractArrayImpl

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

Construct a general object, called from subclass.

Parameters:

objectId - the index of the object

address - the actual address

classInstance - the type of the object

length - the length of the array in elements

Method Details

getInfo

public Object getInfo()

Gets the cached information about the contents of the array.

Returns:

the cached data (parser specific).

setInfo

public void setInfo(Object content)

Sets the cached information about the contents of the array.

Parameters:

content - from the IObjectReader

getLength

public int getLength()

Description copied from interface: IArray

Returns the length of the array in elements.

Specified by:

getLength in interface IArray

Returns:

the length

setLength

public void setLength(int i)

Sets the length in elements.

Parameters:

i - the new length

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

Overrides:

getTechnicalName in class AbstractObjectImpl

Returns:

technical name of this object which is something like class@address

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

Overrides:

getObjectId in class AbstractObjectImpl

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

Overrides:

getObjectAddress in class AbstractObjectImpl

Returns:

address for the snapshot object
