Constructors

Modifier	Constructor	Description
protected	LongObjectRecord(byte tag, long address, long previousAddress, long classAddress, int hashCode, ReferenceIterator references, boolean is64Bit, boolean is32BitHash)	Alternative constructor for use by object array record - the structure of that record is essentially identical with a different tag.
	LongObjectRecord(long address, long previousAddress, long classAddress, int hashCode, ReferenceIterator references, boolean is64Bit, boolean is32BitHash)
