Confidence (ibi Patterns Learn Library Documentation)

All Known Implementing Classes:

ConfDefault, ConfFeature, ConfNone, ConfQFeature, ConfQNone, ConfRatio, ConfRatioLabel, ConfStats
```
public interface Confidence
```
Defines a confidence measure and its options. All implementations must be immutable. Confidence values for all measures must belong to interval [0; 1].

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`int`	`getConfType()`	Return the confidence type.
`double`	`getDblArg(int idx)`	Return a double parameter.
`int`	`getIntArg(int idx)`	Return an integer parameter.

- Method Detail
  - getConfType
```
int getConfType()
```
    Return the confidence type. Must return the correct confidence type for the associated confidence measure.
    
    Returns:
    
    the confidence type.
  - getIntArg
```
int getIntArg(int idx)
```
    Return an integer parameter.
    Confidence measures have integer or double value tuning parameters. They are indexed zero thru N-1. This returns the indicated parameter. The order of the parameters must be coordinated with the order expected in the conf_parms_set_jni macro defined in rlink.h.
    A value must have a predefined value that indicates it is not set. For integers the value used is typically -1.
    
    Parameters:
    
    idx - the integer parameter index, zero based.
    
    Returns:
    
    the integer parameter. If the index is invalid for this confidence measure an arbitrary value may be returned.
  - getDblArg
```
double getDblArg(int idx)
```
    Return a double parameter.
    Confidence measures have integer or double value tuning parameters. They are indexed zero thru N-1. This returns the indicated parameter.
    A value must have a predefined value that indicates it is not set. For doubles the value used is typically -1.0.
    
    Parameters:
    
    idx - the double parameter index, zero based.
    
    Returns:
    
    the double parameter. If the index is invalid for this confidence measure an arbitrary value may be returned.
