equals back to summary

equals	back to summary
public final boolean equals(Object o) Implements abstract java.lang.Record.equals. Doc from java.lang.Record.equals. Indicates whether some other object is "equal to" this one. In addition to the general contract of `Object.equals`, record classes must further obey the invariant that when a record instance is "copied" by passing the result of the record component accessor methods to the canonical constructor, as follows: R copy = new R(r.c1(), r.c2(), ..., r.cn()); then it must be the case that `r.equals(copy)`.

public final boolean equals(Object o)

Implements abstract java.lang.Record.equals.

Doc from java.lang.Record.equals.

Indicates whether some other object is "equal to" this one. In addition to the general contract of Object.equals, record classes must further obey the invariant that when a record instance is "copied" by passing the result of the record component accessor methods to the canonical constructor, as follows:

    R copy = new R(r.c1(), r.c2(), ..., r.cn());

then it must be the case that r.equals(copy).

hashCode back to summary

hashCode	back to summary
public final int hashCode() Implements abstract java.lang.Record.hashCode. Doc from java.lang.Record.hashCode. Returns a hash code value for the record. Obeys the general contract of `Object.hashCode`. For records, hashing behavior is constrained by the refined contract of `Record.equals`, so that any two records created from the same components must have the same hash code.

public final int hashCode()

Implements abstract java.lang.Record.hashCode.

Doc from java.lang.Record.hashCode.

Returns a hash code value for the record. Obeys the general contract of Object.hashCode. For records, hashing behavior is constrained by the refined contract of Record.equals, so that any two records created from the same components must have the same hash code.

parse	back to summary
public static OSVersion parse(String str) throws IllegalArgumentException Returns A Version parsed from a version string split on "." characters. Only major, minor, and micro version numbers are parsed, finer detail is ignored. Missing values for minor and micro are replaced with zero. The string must start with a number, if there is a '.' it must be followed by a number. Parsed by hand because it is called before RegEx can be initialized safely. Parameters str:String a version string Returns:OSVersion A Version parsed from a version string split on "." characters Exceptions IllegalArgumentException: if the string does not start with digits or digits do not follow '.'

parse

back to summary

public static OSVersion parse(String str) throws IllegalArgumentException

Returns A Version parsed from a version string split on "." characters. Only major, minor, and micro version numbers are parsed, finer detail is ignored. Missing values for minor and micro are replaced with zero. The string must start with a number, if there is a '.' it must be followed by a number.

Parsed by hand because it is called before RegEx can be initialized safely.

Parameters

str:String: a version string

Returns:OSVersion

A Version parsed from a version string split on "." characters

Exceptions

IllegalArgumentException:: if the string does not start with digits or digits do not follow '.'

skipDigits	back to summary
private static int skipDigits(String s, int start) Returns The index of the first non-digit from start. Returns:int The index of the first non-digit from start Exceptions IllegalArgumentException: if there are no digits

skipDigits

back to summary

private static int skipDigits(String s, int start)

Returns The index of the first non-digit from start.

Returns:int

The index of the first non-digit from start

Exceptions

IllegalArgumentException:: if there are no digits

toString back to summary

toString	back to summary
public String toString() Implements abstract java.lang.Record.toString. Doc from java.lang.Record.toString. Returns a string representation of the record. In accordance with the general contract of `Object#toString()`, the `toString` method returns a string that "textually represents" this record. The result should be a concise but informative representation that is easy for a person to read. In addition to this general contract, record classes must further participate in the invariant that any two records which are equal must produce equal strings. This invariant is necessarily relaxed in the rare case where corresponding equal component values might fail to produce equal strings for themselves. Annotations @Override
