Class StreamVersion

java.lang.Object

WildMagic.LibGraphics.ObjectSystem.StreamVersion

All Implemented Interfaces:

Serializable

public class StreamVersion
extends Object
implements Serializable

Scene graphs are stored in files with extension wmof. The header is of the form "Wild Magic Object File 4.xx" where the major version is 4 and the the minor version is xx in [00,99]. The length of the string is 27, but the null terminator is written to disk, so total number of file bytes used by the version is 28. The current version is "4.02"

Parameters:

iMajor - the major version number

iMinor - the minor version number

StreamVersion

public StreamVersion(String acString)

public int GetMajor()

Return the major version number

Returns:

the major version number

the minor version number

GreaterEqual

public boolean GreaterEqual(StreamVersion rkVersion)

For comparisons of versions. This is useful in the Stream support in an Object-derived class whenever a change to that class causes a file format change.

Parameters:

rkVersion - the StreamVersion to comare with

Returns:

if this StreamVersion is greater or equal to the input StreamVersion

IsValid

public boolean IsValid()

The version is valid if major is 4 and minor in [0,99].

Returns:

valid if major is 4 and minor in [0,99].

GetCombined

protected int GetCombined()

Returns the combined version number values: 100*major + minor
