- io.debezium.connector.sqlserver.Lsn

All Implemented Interfaces:

Nullable, Comparable<Lsn>
```
public class Lsn
extends Object
implements Comparable<Lsn>, Nullable
```
A logical representation of SQL Server LSN (log sequence number) position. When LSN is not available it is replaced with NULL constant.

    Returns:
    
    binary representation of the stored LSN
  - isAvailable
```
public boolean isAvailable()
```
    Specified by:
    
    isAvailable in interface Nullable
    
    Returns:
    
    true if this is a real LSN or false it it is NULL

    textual representation of the stored LSN
  - valueOf
```
public static Lsn valueOf(String lsnString)
```
    Parameters:
    
    lsnString - - textual representation of Lsn
    
    Returns:
    
    LSN converted from its textual representation
  - valueOf
```
public static Lsn valueOf(byte[] lsnBinary)
```
    Parameters:
    
    lsnBinary - - binary representation of Lsn
    
    Returns:
    
    LSN converted from its binary representation
  - hashCode
```

```
    Overrides:
    
    equals in class Object
  - compareTo
```
public int compareTo(Lsn o)
```
    Enables ordering of LSNs. The NULL LSN is always the smallest one.
    
    Specified by:
    
    compareTo in interface Comparable<Lsn>
  - isBetween
```
public boolean isBetween(Lsn from,
                         Lsn to)
```
    Verifies whether the LSN falls into a LSN interval
    
    Parameters:
    
    from - start of the interval (included)
    
    to - end of the interval (excluded)
    
    Returns:
    
    true if the LSN falls into the interval
