All Implemented Interfaces:

Serializable, Serialiser<RBMBackedTimestampSet,byte[]>, ToBytesSerialiser<RBMBackedTimestampSet>
```
public class RBMBackedTimestampSetSerialiser
extends Object
implements ToBytesSerialiser<RBMBackedTimestampSet>
```
A RBMBackedTimestampSetSerialiser serialises a RBMBackedTimestampSet to an array of bytes.
The following figures illustrate the serialised size of some RBMBackedTimestampSets with different numbers of timestamps added and different time buckets:
- When the time bucket is a minute and 100 random minutes from a single day are added then the serialised size is approximately 210 bytes.
- When the time bucket is a minute and every minute in a single year is added then the serialised size is approximately 73000 bytes.
- When the time bucket is a second and every second in a single year is added then the serialised size is approximately 4,000,000 bytes.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`boolean`	`canHandle(Class clazz)`	Check whether the serialiser can serialise a particular class.
`RBMBackedTimestampSet`	`deserialise(byte[] bytes)`	Deserialise an array of bytes into the original object.
`RBMBackedTimestampSet`	`deserialise(byte[] allBytes, int offset, int length)`
`RBMBackedTimestampSet`	`deserialiseEmpty()`	Handle an empty byte array and reconstruct an appropriate representation in T form.
`boolean`	`equals(Object obj)`
`int`	`hashCode()`
`boolean`	`isConsistent()`	Indicates whether the serialisation process produces a predictable, consistent OUTPUT, from a given INPUT, ie the same object should always serialise in the same way for this to be true.
`boolean`	`preservesObjectOrdering()`	Indicates whether the serialisation process preserves the ordering of the T, i.e.
`byte[]`	`serialise(RBMBackedTimestampSet rbmBackedTimestampSet)`	Serialise some object and returns the raw bytes of the serialised form.

  - canHandle
```
public boolean canHandle(Class clazz)
```
    Description copied from interface: Serialiser
    Check whether the serialiser can serialise a particular class.
    //Warning: Due to erasure you may get false positives. e.g.
    Set<Foo> set = Sets.newHashSet(); boolean b = new Serialiser<Set<Bar>, byte[]>().canHandle(set.getClass()); b will incorrectly be true because of type erasure between Set<Foo> Set<Bar>
    Specified by:
    
    canHandle in interface Serialiser<RBMBackedTimestampSet,byte[]>
    
    Parameters:
    
    clazz - the object class to serialise
    
    Returns:
    
    boolean true if it can be handled

public byte[] serialise(RBMBackedTimestampSet rbmBackedTimestampSet)
                 throws SerialisationException
```
    Description copied from interface: ToBytesSerialiser
    
    Serialise some object and returns the raw bytes of the serialised form.
    
    Specified by:
    
    serialise in interface Serialiser<RBMBackedTimestampSet,byte[]>
    
    Specified by:
    
    serialise in interface ToBytesSerialiser<RBMBackedTimestampSet>
    
    Parameters:
    
    rbmBackedTimestampSet - the object to be serialised
    
    Returns:
    
    byte[] the serialised bytes
    
    Throws:
    
    SerialisationException - if the object fails to serialise
  - deserialise
```
public RBMBackedTimestampSet deserialise(byte[] allBytes,
                                         int offset,
                                         int length)
                                  throws SerialisationException
```
    Specified by:
    
    deserialise in interface ToBytesSerialiser<RBMBackedTimestampSet>
    
    Parameters:
    
    allBytes - The bytes to be decoded into characters
    
    offset - The index of the first byte to decode
    
    length - The number of bytes to decode
    
    Returns:
    
    T the deserialised object
    
    Throws:
    
    SerialisationException - issues during deserialisation
  - deserialise
```
public RBMBackedTimestampSet deserialise(byte[] bytes)
                                  throws SerialisationException
```
    Description copied from interface: ToBytesSerialiser
    
    Deserialise an array of bytes into the original object.
    
    Specified by:
    
    deserialise in interface Serialiser<RBMBackedTimestampSet,byte[]>
    
    Specified by:
    
    deserialise in interface ToBytesSerialiser<RBMBackedTimestampSet>
    
    Parameters:
    
    bytes - the bytes to deserialise
    
    Returns:
    
    T the deserialised object
    
    Throws:
    
    SerialisationException - if the object fails to deserialise
    Note that this implementation is less efficient than using deserialise with an offset and a length, but may still be used if necessary. It has been marked deprecated but will not be removed as it is needed in the Serialiser interface.

    Returns:

  - preservesObjectOrdering
```
public boolean preservesObjectOrdering()
```
    Description copied from interface: ToBytesSerialiser
    
    Indicates whether the serialisation process preserves the ordering of the T, i.e. if x and y are objects of class T, and x is less than y, then this method should return true if the serialised form of x is guaranteed to be less than the serialised form of y (using the standard ordering of byte arrays). If T is not Comparable then this test makes no sense and false should be returned.
    
    Specified by:
    
    preservesObjectOrdering in interface Serialiser<RBMBackedTimestampSet,byte[]>
    
    Specified by:
    
    preservesObjectOrdering in interface ToBytesSerialiser<RBMBackedTimestampSet>
    
    Returns:
    
    true if the serialisation will preserve the order of the T, otherwise false.
  - isConsistent
```
public boolean isConsistent()
```
    Description copied from interface: Serialiser
    
    Indicates whether the serialisation process produces a predictable, consistent OUTPUT, from a given INPUT, ie the same object should always serialise in the same way for this to be true.
    
    Specified by:
    
    isConsistent in interface Serialiser<RBMBackedTimestampSet,byte[]>
    
    Returns:
    
    true if serialisation is consistent for a given object, otherwise false.
