Method Detail

getMajor

public int getMajor()

getMinor

public int getMinor()

getPatch

public int getPatch()

getPreRelease

public String getPreRelease()

getPreReleaseComponents

public String[] getPreReleaseComponents()

getBuild

parse

public static SemanticVersion parse(String input)
                             throws SemanticVersion.InvalidVersionException

Attempts to parse a string as a semantic version according to the Semver 2.0.0 specification.

Parameters:

input - the input string

Returns:

a SemanticVersion instance

Throws:

SemanticVersion.InvalidVersionException - if the version could not be parsed

parse

public static SemanticVersion parse(String input,
                                    boolean allowMissingMinorAndPatch)
                             throws SemanticVersion.InvalidVersionException

Attempts to parse a string as a semantic version according to the Semver 2.0.0 specification, except that the minor and patch versions may optionally be omitted.

Parameters:

input - the input string

allowMissingMinorAndPatch - true if the parser should tolerate the absence of a minor and/or patch version; if absent, they will be treated as zero

Returns:

a SemanticVersion instance

Throws:

SemanticVersion.InvalidVersionException - if the version could not be parsed

compareTo

public int compareTo(SemanticVersion other)

Specified by:

compareTo in interface Comparable<SemanticVersion>

comparePrecedence

public int comparePrecedence(SemanticVersion other)

Compares this object with another SemanticVersion according to Semver 2.0.0 precedence rules.

Parameters:

other - another SemanticVersion

Returns:

0 if equal, -1 if the current object has lower precedence, or 1 if the current object has higher precedence
