Constructor Detail

GwtVersion

public GwtVersion()

Create a version that avoids any nagging -- "0.0.999".

GwtVersion

public GwtVersion(String versionString)
           throws NumberFormatException

Parse a version number as a string. An empty or null string are explicitly allowed and are equivalent to "0.0.0".

Acceptable format:

• prefix before first digit is ignored
• one or more digits or strings separated by a period
• optional release number suffix, such as -ms1, -rc3, etc.
• stops parsing at first space or dash

The returned version always contains at least 3 components (padding with "0" to 3 components) followed by a release number (which is always last).

Parameters:

versionString - GWT version in string form, ex: "2.1.0-rc2"

Throws:

NumberFormatException
