InstanceImpl
Construct a representation of plain java object in the snapshot.- Parameters:
objectId- the object idaddress- the actual addressclazz- the type of the objectfields- the instance fields of the object (the static fields are held in the class)

Method Details

getObjectAddress
public long getObjectAddress()Description copied from interface:IObjectGet 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:
getObjectAddressin interfaceIObject- Overrides:
getObjectAddressin classAbstractObjectImpl- Returns:
- address for the snapshot object
-
getObjectId
public int getObjectId()Description copied from interface:IObjectGet id for the snapshot object. The id is not the address, but an internally assigned number fitting into anint(this helps reducing the memory footprint of the snapshot considerably - addresses are only used for visualization purposes).- Specified by:
getObjectIdin interfaceIObject- Overrides:
getObjectIdin classAbstractObjectImpl- Returns:
- id for the snapshot object
-
getFields
Description copied from interface:IInstanceReturns all fields of the object.Fields are ordered in such a way, that first fields defined in the current class and then fields of the super class and its super classes are returned. This order is important to know, if a class declares a field by the same name as the class it inherits from.
-
getField
Description copied from interface:IInstanceReturns the field identified by the name.If declares a member variable by the same name as the parent class does, then the result of this method is undefined.
-
getUsedHeapSize
public long getUsedHeapSize()Description copied from interface:IObjectGet used heap size of just this object.- Specified by:
getUsedHeapSizein interfaceIObject- Specified by:
getUsedHeapSizein classAbstractObjectImpl- Returns:
- used heap size of this object
-
getReferences
Description copied from class:AbstractObjectImplGets the outbound references from this object, as addresses.- Specified by:
getReferencesin classAbstractObjectImpl- Returns:
- a list of outbound references
-
getOutboundReferences
Description copied from interface:IObjectGet list of snapshot objects referenced from this snapshot object with the name of the field over which it was referenced.- Specified by:
getOutboundReferencesin interfaceIObject- Returns:
- list of snapshot objects referenced from this snapshot object with the name of the field over which it was referenced
