Method Detail

fromByteBuffer

T fromByteBuffer(ByteBuffer buffer)
                 throws IOException,
                        UnsupportedOperationException

Deserialize an object from a byte buffer (e.g. disk)

Parameters:

buffer - Data array to process

Returns:

Deserialized object

Throws:

IOException - on IO errors

UnsupportedOperationException - When functionality not implemented or available

toByteBuffer

void toByteBuffer(ByteBuffer buffer,
                T object)
                  throws IOException,
                         UnsupportedOperationException

Serialize the object to a byte array (e.g. disk)

Parameters:

buffer - Buffer to serialize to

object - Object to serialize

Throws:

IOException - on IO errors

UnsupportedOperationException - When functionality not implemented or available

getByteSize

int getByteSize(T object)
                throws IOException,
                       UnsupportedOperationException

Get the size of the object in bytes.

Parameters:

object - Object to serialize

Returns:

maximum size in serialized form

Throws:

IOException - on IO errors

UnsupportedOperationException - When functionality not implemented or available
