Method Detail

writeObject

public void writeObject(FSTObjectOutput out,
               Object toWrite,
               FSTClazzInfo clzInfo,
               FSTClazzInfo.FSTFieldInfo referencedBy,
               int streamPosition)
                 throws IOException

Description copied from interface: FSTObjectSerializer

write the contents of a given object

Throws:

IOException

instantiate

public Object instantiate(Class objectClass,
                 FSTObjectInput in,
                 FSTClazzInfo serializationInfo,
                 FSTClazzInfo.FSTFieldInfo referencee,
                 int streamPositioin)
                   throws IOException,
                          ClassNotFoundException,
                          InstantiationException,
                          IllegalAccessException

Description copied from interface: FSTObjectSerializer

return null to delegate object instantiation to FST. If you want to implement object instantiation yourself, usually you leave the readObject method empty and handle instantiation and reading the object here. You must call registerObjectForWrite immediately after creating it on the FSTObjectInput

Specified by:

instantiate in interface FSTObjectSerializer

Overrides:

instantiate in class FSTBasicObjectSerializer

Throws:

IOException

ClassNotFoundException

InstantiationException

IllegalAccessException

alwaysCopy

public boolean alwaysCopy()

Specified by:

alwaysCopy in interface FSTObjectSerializer

Overrides:

alwaysCopy in class FSTBasicObjectSerializer

Returns:

true if FST can skip a search for same instances in the serialized ObjectGraph. This speeds up reading and writing and makes sense for short immutable such as Integer, Short, Character, Date, .. . For those classes it is more expensive (CPU, size) to do a lookup than to just write the Object twice in case.
