|Package Summary Overview Summary|
public static final class ModuleDescriptor.Version extends java.lang.Object implements java.lang.Comparable<ModuleDescriptor.Version>
A version string has three components: The version number itself, an optional pre-release version, and an optional build version. Each component is a sequence of tokens; each token is either a non-negative integer or a string. Tokens are separated by the punctuation characters
'+', or by transitions from a sequence of digits to a sequence of characters that are neither digits nor punctuation characters, or vice versa.
'.'characters, terminated by the first
'-'characters, terminated by the first
When comparing two version strings, the elements of their corresponding components are compared in pointwise fashion. If one component is longer than the other, but otherwise equal to it, then the first component is considered the greater of the two; otherwise, if two corresponding elements are integers then they are compared as such; otherwise, at least one of the elements is a string, so the other is converted into a string if it is an integer and the two are compared lexicographically. Trailing integer elements with the value zero are ignored.
Given two version strings, if their version numbers differ then the result of comparing them is the result of comparing their version numbers; otherwise, if one of them has a pre-release version but the other does not then the first is considered to precede the second, otherwise the result of comparing them is the result of comparing their pre-release versions; otherwise, the result of comparing them is the result of comparing their build versions.
|Modifier and Type||Method||Description|
Compares this module version to another module version.
Tests this module version for equality with the given object.
Computes a hash code for this module version.
Parses the given string as a version string.
Returns the string from which this version was parsed.
public static ModuleDescriptor.Version parse(java.lang.String v)
v- The string to parse
null, an empty string, or cannot be parsed as a version string
public int compareTo(ModuleDescriptor.Version that)
that- The module version to compare
public boolean equals(java.lang.Object ob)
If the given object is not a
Version then this method returns
false. Two module version are equal if their corresponding components are equal.
This method satisfies the general contract of the
ob- the object to which this object is to be compared
trueif, and only if, the given object is a module reference that is equal to this module reference
public int hashCode()
The hash code is based upon the components of the version and satisfies the general contract of the
public java.lang.String toString()
