Method Summary

Methods

Modifier and Type	Method and Description
boolean	alwaysCopy()
Object	instantiate(Class objectClass, FSTObjectInput fstObjectInput, FSTClazzInfo serializationInfo, FSTClazzInfo.FSTFieldInfo referencee, int streamPositioin) return null to delegate object instantiation to FST.
void	readObject(FSTObjectInput in, Object toRead, FSTClazzInfo clzInfo, FSTClazzInfo.FSTFieldInfo referencedBy) read the content to an already instantiated object
boolean	willHandleClass(Class cl) useful if you register for a class and its subclasses, but want to exclude a specific subclass
void	writeObject(FSTObjectOutput out, Object toWrite, FSTClazzInfo clzInfo, FSTClazzInfo.FSTFieldInfo referencedBy, int streamPosition) write the contents of a given object

Method Detail

writeObject

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

write the contents of a given object

Throws:

IOException

readObject

void readObject(FSTObjectInput in,
              Object toRead,
              FSTClazzInfo clzInfo,
              FSTClazzInfo.FSTFieldInfo referencedBy)
                throws IOException,
                       ClassNotFoundException,
                       IllegalAccessException,
                       InstantiationException

read the content to an already instantiated object

Throws:

IOException

ClassNotFoundException

IllegalAccessException

InstantiationException

willHandleClass

boolean willHandleClass(Class cl)

useful if you register for a class and its subclasses, but want to exclude a specific subclass

alwaysCopy

boolean alwaysCopy()

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.

instantiate

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

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

Throws:

IOException

ClassNotFoundException

InstantiationException

IllegalAccessException
