All Implemented Interfaces:: CapabilitiesHandler, OptionHandler, RevisionHandler

public class FindWithCapabilities
extends java.lang.Object
implements OptionHandler, CapabilitiesHandler, RevisionHandler

Locates all classes with certain capabilities. One should keep in mind, that works only with the default capabilities of a scheme and doesn't take dependencies into account. E.g., a meta-classifier that could have a base classifier handling numeric classes, but by default uses one with a nominal class, will never show up in a search for schemes that handle numeric classes.

Valid options are:

 All class and attribute options can be prefixed with 'not',
 e.g., '-not-numeric-class'. This makes sure that the returned
 schemes 'cannot' handle numeric classes.

 -num-instances <num>
  The minimum number of instances (default 1).

 -unary-class
  Must handle unray classes.

 -binary-class
  Must handle binary classes.

 -nominal-class
  Must handle nominal classes.

 -numeric-class
  Must handle numeric classes.

 -string-class
  Must handle string classes.

 -date-class
  Must handle date classes.

 -relational-class
  Must handle relational classes.

 -missing-class-values
  Must handle missing class values.

 -no-class
  Doesn't need a class.

 -unary-atts
  Must handle unary attributes.

 -binary-atts
  Must handle binary attributes.

 -nominal-atts
  Must handle nominal attributes.

 -numeric-atts
  Must handle numeric attributes.

 -string-atts
  Must handle string attributes.

 -date-atts
  Must handle date attributes.

 -relational-atts
  Must handle relational attributes.

 -missing-att-values
  Must handle missing attribute values.

 -only-multiinstance
  Must handle multi-instance data.

 -W <classname>
  The Capabilities handler to base the handling on.
  The other parameters can be used to override the ones
  determined from the handler. Additional parameters for
  handler can be passed on after the '--'.
  Either '-W' or '-t' can be used.

 -t <file>
  The dataset to base the capabilities on.
  The other parameters can be used to override the ones
  determined from the handler.
  Either '-t' or '-W' can be used.

 -c <num>
  The index of the class attribute, -1 for none.
  'first' and 'last' are also valid.
  Only in conjunction with option '-t'.

 -superclass
  Superclass to look for in the packages.

 -packages
  Comma-separated list of packages to search in.

 -generic
  Retrieves the package list from the GenericPropertiesCreator
  for the given superclass. (overrides -packages <list>).

 -misses
  Also prints the classname that didn't match the criteria.
