Interface Summary

ArrayChoice	a representation of a choice among arrays within a dataset.
DataAccess	an interface for accessing data from a data file.
ReaderND
TransferFunction.Changes	constants used to identify changes that can be made to a transfer function.
TransferFunction.Listener	classes interested in changes to this function can implement this interface
ViewableListener	an interface for listening for ViewableUpdateEvents from Viewables
ViewSpecs.Hints	constants representing hints for creating images
ViewStack	an interface to a stack of visualizations created from data in a ViewableList.

Class Summary

ArrayNDCache	ArrayNDCache This class provides the caching mechanism whereby various arrayNDs can be cached for future use.
CachedDataND	CachedDataND.java An object of this class represents a DataND whose array is known to be cached.
CachingDataNDImageProducer	an Image Producer that creates images from data in a DataND object, applying certain caching strategies as needed.
CompositeView2D	a two dimensional, combined visualization of one or more N-dimensional arrays of scientific data (i.e. from one ViewableList).
DataAccessEnabledViewable	a Viewable that creates images from an array accessible via a DataAccess object This class simplifies supporting a specific data format through a Viewable class by encapsulating out the access to the data into a DataAccess object.
DataNDImageSource	an Image Producer that creates images from data in a DataND object.
DataND	An abstract class representing a window on an N-dimensional array located within a measurement space.
Dataset	a representation of a source of zero or more N-dimensional arrays.
DirectTransferFunction	A transfer function which assumes that the input data can be used directly as the quantized data.
EasyView2DStack	a View2DStack with helper methods for adding the View2D objects incrementally.
EmptyDataND	a DataND with no defined data in it.
FileFormatLookup	a class that will examine a file or stream to determine its format based on characterisitcs stored in internal lookup tables.
FileFormat	a representation of the format of a file and methods for handling it.
FormatHandler	a class that handles the creation of a format-specific Viewable to access a specific array from a Dataset.
GenericViewable	a Viewable wrapper for visualizing data from an internal ND array.
HorizonMetadata	a Metadata class with extra help to support the Horizon schema
IndexArrayChoice	a representation of a choice among sequentially ordered arrays within a dataset.
InMemoryDataND	A DataND in which the data array is stored entirely within memory.
MutableView2DStack	a View2DStack with helper methods for adding the View2D objects incrementally.
NumericTransferFunction	a class that applies a linear transfer function to an array of numeric values.
ReaderEnabledViewable
ReaderNDAdapter
SimplySupportedFileFormat	a class encapsulating file formats that are supported through developer-provided FormatHandlers.
SupportedFileFormat	a class encapsulating file formats that are supported through developer-provided code.
TransferFunction	an abstract representation of the mapping of a range of values into discreet bins.
UnknownFileFormat	a representation of an unrecognized file format.
View2D	a two dimensional visualization of scientific data.
View2DStack	a stack of visualizations created from data in a ViewableList.
ViewableList	an ordered list of Viewable datasets
Viewable	a window on a multidimensional data array.
ViewableUpdateEvent	an event indicating that a change has occured in a Viewable.
ViewableUpdateMulticaster	an adapter that will distribute a ViewableUpdateEvent to a chain of Listeners
ViewSpecs	the specifications for producing a visualization from a Viewable dataset
Visualization2D	an abstraction of a two-dimensional visualization of scientific data
Visualization	an abstraction of a visualization of scientific data

Exception Summary

ArrayTooBigException	This exception is thrown when the array needing to be stored exceeds the memoryCapacity of the ArrayCache, which by default is 2/3 of freeMemory() in the beginning of execution.
BadTransferFunctionException	an Exception thrown when one attempts to use a TransferFunction that is is inappropriate for a given type of data
DataAccessException	an exception while trying to access data.
DataFormatException	an exception indicating that a data file format error was encountered while trying to access data.
DataIOException	an IO exception while trying to access data.
RereadNotSupportedException	an exception indicating that a reread of data was requested or attempted on a source that could not be reread (e.g. an unrewindable, unnamed input stream).
UnsupportedFormatException	an Exception thrown if Horizon system is not properly configured to handle a particular file format in an automated way.
