Description

Interface Summary

Attribute	Attributes should hold all information about a single attribute.
Attributes	This container holds all information about the example set attributes.
AttributeTransformation	This interface is used to define on-the-fly transformations in data views.
ExampleFormatter.FormatCommand	Represents one piece of formatting.
ExampleReader	An ExampleReader iterates over a sequence of examples.
ExampleSet	Interface definition for all example sets.
Statistics	The superclass for all attribute statistics objects.

Class Summary

AbstractAttributes	This is the abstract superclass for all attribute set implementations.
AttributeDescription	This class holds all basic information about an attribute.
AttributeIterator	Iterates over either only the regular attribute, only the special attributes, or over all all attributes.
AttributeParser	Parses a file containing construction descriptions and adds the new attributes to the example set.
AttributeRole	This class holds the example set relevant information about a table attribute, i.e.
AttributeRoleIterator	An iterator for attribute roles which is able to iterate over all attributes or skip either regular or special attributes.
AttributeWeight	Helper class containing the name of an attribute and the corresponding weight.
AttributeWeights	AttributeWeights holds the information about the weights of attributes of an example set.
DelegateAttributes	Deprecated. Please extend AbstractAttributes instead since using this class might lead to stack overflow errors in cases where a large amount of iterations is performed
Example	An example consists of a DataRow and some convenience methods to access the data.
ExampleFormatter	Formats an example as specified by the format string.
ExampleFormatter.SimpleCommand	Implements some simple format commands like 'a' for all attributes or 'l' for the label.
ExampleFormatter.TextCommand	Returns simply the given text.
ExampleFormatter.ValueCommand	Returns the value of an argument which must be an attribute's name.
ExampleSetFactory	This class can be used to easily create @link ExampleSet}s and the underlying ExampleTable with simple method calls.
FastExample2SparseTransform	This class can be used for the efficient generation of sparse example formats.
MinMaxStatistics	Attribute statistics object for (pseudo-)numerical attributes like real numerical attributes or date attributes.
NominalStatistics	Attribute statistics object for nominal attributes.
NumericalStatistics	Attribute statistics object for numerical attributes.
SimpleAttributes	A very basic and simple implementation of the Attributes interface based on a linked list of AttributeRoles and simply delivers the same AttributeRoleIterator which might skip either regular or special attributes.
Tools	Provides some tools for calculation of certain measures and feature generation.
UnknownStatistics	The superclass for all attribute statistics objects.
WeightedNumericalStatistics	Attribute statistics object for weighted numerical attributes.

Exception Summary

AttributeTypeException	This exception will be thrown if operators use properties of attributes which are not supported by this attribute, for example, if a nominal mapping of the third value is retrieved from a binominal attribute.
FormatterException	This exception is thrown by the ExampleFormatter if the user specified format is not applicable to an example set.

Package com.rapidminer.example Description

The data core classes of RapidMiner. These perform both data and attribute handling. The basic idea is that of a small database management system: the data itself is stored in an example table (please note that this interface can stand for all types of data sources, memory, databases, and files) and views on this table (example sets) are provided.
