PhaseIbs

All Known Implementing Classes:

LowFreqPhaseIbs, PbwtPhaseIbs
```
public interface PhaseIbs
```
Instances of interface PhaseIbs identify haplotypes that are identical by state with a specified haplotype in a specified genomic interval.

All instances of PhaseIbs are required to be immutable.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`addIbsHaps(int hap, int step, PhaseStates phaseStates)`	Adds haplotypes that are IBS with the specified haplotype to the HMM state space.
`PhaseData`	`phaseData()`	Returns the input data for the next phase update.

- Method Detail
  - phaseData
```
PhaseData phaseData()
```
    Returns the input data for the next phase update.
    
    Returns:
    
    the input data for the next phase update
  - addIbsHaps
```
void addIbsHaps(int hap,
                int step,
                PhaseStates phaseStates)
```
    Adds haplotypes that are IBS with the specified haplotype to the HMM state space.
    
    Parameters:
    
    hap - a haplotype index
    
    step - an index of a genomic interval
    
    phaseStates - the object for constructing the HMM state space
    
    Throws:
    
    java.lang.IndexOutOfBoundsException - if hap < 0 || hap >= this.phaseData().targGT().nHaps()
    
    java.lang.IndexOutOfBoundsException - if step < 0 || step >= this.codedSteps().nSteps()
    
    java.lang.NullPointerException - if phaseStates == null
