setOffset

public void setOffset(int offset)

Specified by:

setOffset in interface IField

getRecordSize

public int getRecordSize()

Specified by:

getRecordSize in interface IField

hasReferences

public boolean hasReferences(Nd nd,
                             long address)

Description copied from interface: IRefCountedField

Returns true if this field knows of any remaining incoming references to this object. This is used by the implementation of FieldManyToOne to determine whether or not a refcounted object should be deleted after a reference is removed.

Implementations should return false if the refcount is 0 or true if the refcount is nonzero.

Specified by:

hasReferences in interface IRefCountedField
