Method Detail

newInstance

public Object newInstance(EntityInput input,
                          boolean rawAccess)
                   throws RefreshException

Description copied from class: Format

Creates a new instance of the target class using its default constructor. Normally this creates an empty object, and readObject() is called next to fill in the contents. This is done in two steps to allow the instance to be registered by EntityInput before reading the contents. This allows the fields in an object or a nested object to refer to the parent object in a graph. Alternatively, this method may read all or the first portion of the data, rather than that being done by readObject(). This is required for simple types and enums, where the object cannot be created without reading the data. In these cases, there is no possibility that the parent object will be referenced by the child object in the graph. It should not be done in other cases, or the graph references may not be maintained faithfully. Is public only in order to implement the Reader interface. Note that this method should only be called directly in raw conversion mode or during conversion of an old format. Normally it should be called via the getReader method and the Reader interface.

readObject

public Object readObject(Object o,
                         EntityInput input,
                         boolean rawAccess)
                  throws RefreshException

Description copied from class: Format

Called after newInstance() to read the rest of the data bytes and fill in the object contents. If the object was read completely by newInstance(), this method does nothing. Is public only in order to implement the Reader interface. Note that this method should only be called directly in raw conversion mode or during conversion of an old format. Normally it should be called via the getReader method and the Reader interface.
