iterator begin ()
 Iterator to first element.
iterator begin (const Box3i &subset)
 Iterator to first element of specific subset.
virtual void clear (const Data_T &value)
 Clears all the voxels in the storage. Should be re-implemented by subclasses that can provide a more efficient version.

 Iterator pointing one element past the last valid one.
iterator end (const Box3i &subset)
 Iterator pointing one element past the last valid one (for a subset)
virtual Data_T & lvalue (int i, int j, int k)=0
 Write access to a voxel. The coordinates are global coordinates.

const_iterator cbegin () const
 Const iterator to first element. "cbegin" matches the tr1 c++ standard.

 Dtor.
- Public Member Functions inherited from FieldRes
V3i const dataResolution () const
const Box3idataWindow () const
 Returns the data window. Any coordinate inside this window is safe to pass to value() in the Field subclass.
const Box3iextents () const
 Returns the extents of the data. This signifies the relevant area that the data exists over. However, the data window (below) may be smaller than the extents, in which case it is only safe to call value() for those coordinate inside the data window.

 This constructor ensures that we have a valid mapping at all times.

 Base class copy constructor.
bool isInBounds (int i, int j, int k) const

virtual std::string className () const =0
 Returns the class name of the object. Used by the class pool and when writing the data to disk.
virtual Ptr clone () const =0
 Returns a pointer to a copy of the field, pure virtual so ensure derived classes properly implement it.

 accessor to the m_metadata class
const FieldMetadata< FieldBase > & metadata () const
 Read only access to the m_metadata class.

 Copy constructor.
RefBaseoperator= (const RefBase &)
 Assignment operator.
virtual ~RefBase ()
 Destructor.
virtual bool checkRTTI (const char *typenameStr)=0
 This function is only implemented by concrete classes and triggers the actual RTTI check through matchRTTI();.
bool matchRTTI (const char *typenameStr)
 Performs a check to see if the given typename string matches this class' This needs to be implemented in -all- subclasses, even abstract ones.

- Protected Attributes inherited from FieldRes
Box3i m_dataWindow
 Defines the area where data is allocated. This should be treated as a closed (i.e. inclusive) interval.
Box3i m_extents
 Defines the extents of the the storage. This may be larger or smaller than the data window, and in the case where it is larger, care must be taken not to access voxels outside the data window. This should be treated as a closed (i.e. inclusive) interval.
FieldMapping::Ptr m_mapping
 Pointer to the field's mapping.

Detailed Description

template<class Data_T>
class ResizableField< Data_T >

This class adds the ability to resize the data storage object. Most Field subclasses will derive from this class. Only classes that cannot implement sizeChanged() in a reasonable manner should derive from Field or WritableField.
