Method Summary | |
---|---|
(package private) void |
collectRelatedFormats(Catalog catalog,
Map<String,Format> newFormats)
Calls catalog.createFormat for formats that this format depends on, or that should also be persistent. |
(package private) boolean |
evolve(Format newFormat,
Evolver evolver)
Called for an existing format that may not equal the current format for the same class. |
(package private) void |
initialize(Catalog catalog,
int initVersion)
Initializes an uninitialized format, initializing its related formats (superclass formats and array component formats) first. |
(package private) Object |
newArray(int len)
Creates an array of the format's class of the given length, as if Array.newInstance(getType(), len) were called. |
Object |
newInstance(EntityInput input,
boolean rawAccess)
Creates a new instance of the target class using its default constructor. |
Object |
readObject(Object o,
EntityInput input,
boolean rawAccess)
Called after newInstance() to read the rest of the data bytes and fill in the object contents. |
(package private) void |
skipContents(RecordInput input)
Skips over the object's contents, as if readObject() were called, but without returning an object. |
(package private) void |
writeObject(Object o,
EntityOutput output,
boolean rawAccess)
Writes a given instance of the target class to the output data bytes. |

boolean evolve(Format newFormat, Evolver evolver)
Format
If this method returns true, then it must have determined that the old and new formats are equal, and it must have called either Evolver.useOldFormat or useEvolvedFormat. If this method returns false, then it must have determined that the old format could not be evolved to the new format, and it must have called Evolver.addInvalidMutation, addMissingMutation or addEvolveError.
