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 interfaceSerialiser<GroupedProperties,byte[]>
- Overrides:
canHandle
in classPropertiesSerialiser<GroupedProperties>
- Parameters:
clazz
- the object class to serialise- Returns:
- boolean true if it can be handled
-
serialise
public byte[] serialise(GroupedProperties properties) throws SerialisationException
Description copied from interface:ToBytesSerialiser
Serialise some object and returns the raw bytes of the serialised form.- Parameters:
properties
- the object to be serialised- Returns:
- byte[] the serialised bytes
- Throws:
SerialisationException
- if the object fails to serialise
-
deserialise
public GroupedProperties deserialise(byte[] bytes) throws SerialisationException
Description copied from interface:ToBytesSerialiser
Deserialise an array of bytes into the original object.- Parameters:
bytes
- the bytes to deserialise- Returns:
- T the deserialised object
- Throws:
SerialisationException
- if the object fails to deserialiseNote 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.

ToBytesSerialiser.deserialise(byte[], int, int)
-
deserialiseEmpty
public GroupedProperties deserialiseEmpty() throws SerialisationException
Description copied from interface:ToBytesSerialiser
Handle an empty byte array and reconstruct an appropriate representation in T form.- Returns:
- T the deserialised object
- Throws:
SerialisationException
- if the object fails to deserialise
-
getGroup
public String getGroup(byte[] bytes) throws SerialisationException
- Throws:
SerialisationException
-
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.- Returns:
- true if serialisation is consistent for a given object, otherwise false.
