Constructor Details

Version

public Version(int _major,
               int _minor)
Create the version with the given version numbers.
Parameters:
_major - major number (0..255)
_minor - minor number (0..255)

Method Details

equals

public boolean equals(Object other)
Returns true if the versions are equal.
Overrides:
equals in interface Object
Parameters:
other - the other version to compare.
Returns:
true if the versions are equal

hashCode

public int hashCode()
Get the hashcode, higher 8 bits being the major version and lower 8 bits the minor version.
Overrides:
hashCode in interface Object

read_version

public static Version read_version(InputStream in)
Read from the input stream, major number first.
Parameters:
in - a stream to read from.

same

public boolean same(Version that)
Returns true if the versions are the same.
Parameters:
that - the other version to compare.
Returns:
true if the versions are the same.

since_inclusive

public boolean since_inclusive(int a_major,
                               int a_minor)
Returns true if the given version is higher than or equals to the version, supplied as parameter in the form of two integers.
Parameters:
a_major - major number of the version to compare.
a_minor - minor number of the version to compare.
Returns:
true if this version is higher than or equals to the version v.

toString

public String toString()
Return the string representation, in the form major.minor.
Overrides:
toString in interface Object

until_inclusive

public boolean until_inclusive(int a_major,
                               int a_minor)
Returs true if the given version is lower or equal to the version, specified by the provided minor and major version number. This means, the version, specified by these two numbers, should be supported by the current version.
Parameters:
a_major - a major version number.
a_minor - a minor version number.
Returns:
true if the current version should be supported by the version, specified by the two passed numbers.

write

public void write(OutputStream out)
Write into the output stream, major number first.
Parameters:
out - a stream to write into.
