Method Detail

isFixedSerializedSize

public boolean isFixedSerializedSize()

Description copied from interface: Serializer

If a serializer always creates the same number of bytes, containers can choose a fixed-size block for higher performance. If this method returns true, getSerializedSize must return the same value for every access, it may be accessed with a null parameter, and it may be accessed less than once per serialized object.

Specified by:

isFixedSerializedSize in interface Serializer<Float>

Returns:

To indicate that the same number of bytes will be created, return true. Otherwise, there may be a dynamic number of bytes and return false.

getSerializedSize

public long getSerializedSize(Float value)

Description copied from interface: Serializer

Determines the size of the object after serialization. This allows some optimizations avoiding unnecessary copying of data.

The common pattern is:

1. Get size from getSerializedSize
2. Allocate appropriate space
3. Write serialized object with serialize

It may be best to remember the most recently used object between calls to getSerializedSize and serialize when it can reduce processing time.

Specified by:

getSerializedSize in interface Serializer<Float>

Returns:

the exact number of bytes the object will take to serialize

serialize

public void serialize(Float value,
                      OutputStream out)
               throws IOException

Description copied from interface: Serializer

Writes the object to the OutputStream. null will not be passed in.

Specified by:

serialize in interface Serializer<Float>

Throws:

IOException

deserialize

public Float deserialize(InputStream in)
                  throws IOException

Description copied from interface: Serializer

Restores an object from an InputStream.

Specified by:

deserialize in interface Serializer<Float>

Throws:

IOException
