public class MakeIndicator
extends Filter
implements UnsupervisedFilter, StreamableFilter, OptionHandler
A filter that creates a new dataset with a boolean attribute replacing a nominal attribute. In the new dataset, a value of 1 is assigned to an instance that exhibits a particular range of attribute values, a 0 to an instance that doesn't. The boolean attribute is coded as numeric by default.
Valid options are:
-C <col> Sets the attribute index.
-V <index1,index2-index4,...> Specify the list of values to indicate. First and last are valid indexes (default last)
-N <index> Set if new boolean attribute nominal.

getCapabilities
Returns the Capabilities of this filter.- 指定者:
getCapabilities
在接口中CapabilitiesHandler
- 覆盖:
getCapabilities
在类中Filter
- 返回:
- the capabilities of this object
- 另请参阅:
-
setInputFormat
Sets the format of the input instances.- 覆盖:
setInputFormat
在类中Filter
- 参数:
instanceInfo
- an Instances object containing the input instance structure (any instances contained in the object are ignored - only the structure is required).- 返回:
- true if the outputFormat may be collected immediately
- 抛出:
UnsupportedAttributeTypeException
- the selecte attribute is not nominalUnsupportedAttributeTypeException
- the selecte attribute has fewer than two values.Exception
- if the inputFormat can't be set successfully
-
input
Input an instance for filtering. The instance is processed and made available for output immediately.- 覆盖:
input
在类中Filter
- 参数:
instance
- the input instance- 返回:
- true if the filtered instance may now be collected with output().
- 抛出:
IllegalStateException
- if no input format has been set.
-
listOptions
Returns an enumeration describing the available options.- 指定者:
listOptions
在接口中OptionHandler
- 返回:
- an enumeration of all the available options.
-
setOptions
Parses a given list of options. Valid options are:-C <col> Sets the attribute index.
-V <index1,index2-index4,...> Specify the list of values to indicate. First and last are valid indexes (default last)
-N <index> Set if new boolean attribute nominal.
- 指定者:
setOptions
在接口中OptionHandler
- 参数:
options
- the list of options as an array of strings- 抛出:
Exception
- if an option is not supported
-
getOptions
Gets the current settings of the filter.- 指定者:
getOptions
在接口中OptionHandler
- 返回:
- an array of strings suitable for passing to setOptions
-
globalInfo
- 返回:
- a description of the filter suitable for displaying in the explorer/experimenter gui
-
attributeIndexTipText
- 返回:
- tip text for this property suitable for displaying in the explorer/experimenter gui
-
getAttributeIndex
Get the index of the attribute used.- 返回:
- the index of the attribute
-
setAttributeIndex
Sets index of the attribute used.- 参数:
attIndex
- the index of the attribute

-
setValueIndex
public void setValueIndex(int index) Sets index of the indicator value.- 参数:
index
- the index of the indicator value
-
setValueIndicesArray
public void setValueIndicesArray(int[] indices) Set which attributes are to be deleted (or kept if invert is true)- 参数:
indices
- an array containing indexes of attributes to select. Since the array will typically come from a program, attributes are indexed from 0.- 抛出:
InvalidArgumentException
- if an invalid set of ranges is supplied
-
numericTipText
