Method Detail

getType

public static Stat.Type getType(int code)

Maps a Stat.Type's code code back to a Stat.Type instance.

initType

public static int initType(Stat.Type type,
                           Stat prototype)

Used by the Stat.Type implementation to map itself to an integer code.

Returns:

the code to which the supplied type was mapped.

crc32

public static int crc32(String string)

Computes and returns the CRC32 hash of the specified string.

getType

public Stat.Type getType()

Returns the type of this statistic.

getCode

public int getCode()

Returns the integer code to which this statistic's name maps.

isModified

public boolean isModified()

Returns true if the supplied statistic has been modified since it was loaded from the repository.

setModified

public void setModified(boolean modified)

Forces this stat to consider itself modified. Generally this is not called but rather the derived class will update its modified state when it is actually modified.

getModCount

public byte getModCount()

Returns the modification count of this Stat when it was loaded from the repository.

setModCount

public void setModCount(byte modCount)

Sets the modification count for this Stat. StatRepository calls this when converting a StatRecord into a Stat; it shouldn't be called otherwise.

persistTo

public abstract void persistTo(com.threerings.io.ObjectOutputStream out,
                               Stat.AuxDataSource aux)
                        throws IOException

Serializes this instance for storage in the item database. Derived classes must override this method to implement persistence.

Throws:

IOException

unpersistFrom

public abstract void unpersistFrom(com.threerings.io.ObjectInputStream in,
                                   Stat.AuxDataSource aux)
                            throws IOException,
                                   ClassNotFoundException

Unserializes this item from data obtained from the item database. Derived classes must override this method to implement persistence.

Throws:

IOException

ClassNotFoundException

toString

public String toString()

Overrides:

toString in class Object

valueToString

public abstract String valueToString()

Derived statistics must override this method and render their value to a string. Used by toString() and to display the value in game.

getKey

public String getKey()

Specified by:

getKey in interface com.threerings.presents.dobj.DSet.Entry

clone

public Stat clone()

Overrides:

clone in class Object
