```
protected PointsReader()
```
    Sole constructor. (For invocation by subclass constructors, typically implicit.)
- Method Detail
  - checkIntegrity
```
public abstract void checkIntegrity()
                             throws java.io.IOException
```
    Checks consistency of this reader.
    Note that this may be costly in terms of I/O, e.g. may involve computing a checksum value against large data files.
    
    Throws:
    
    java.io.IOException
  - getValues
```
public abstract PointValues getValues(java.lang.String field)
                               throws java.io.IOException
```
    Return PointValues for the given field. The behavior is undefined if the given field doesn't have points enabled on its FieldInfo.
    
    Throws:
    
    java.io.IOException
  - getMergeInstance
```
public PointsReader getMergeInstance()
```
    Returns an instance optimized for merging. This instance may only be used in the thread that acquires it.
    The default implementation returns this
