isCompatibleWith

public static boolean isCompatibleWith(java.lang.String available,
                                       java.lang.String required)

Returns true if the available version is compatible with the required version. Compatibility is defined as the available version being equal to or larger than the required version.

A version string is made up of several numerical components with the most significant one coming first (e.g. 2.1.0 or 99/12/25). The version components are compared one by one starting with the most significant. All version components are compared, if they are missing in their version, zero is assumed (2.1 is equivalent to 2.1.0.0).

Available version 2.x will be compatible with required version 1.x, 1.0 and 1 (the last two are the same) but not with required version 3.x. 2.x will be compatible with 2.y if x and y are independently compatible according to the same rules.

The supported version separators are . , / -.

True: available >= required

Parameters:

available - The available version number

required - The ninimum required version number

Returns:

True if available equals to or larger than the required
