compareTo back to summary

compareTo	back to summary
public int compareTo(Version o) Implements java.lang.Comparable.compareTo. Doc from java.lang.Comparable.compareTo. Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object. The implementor must ensure `signum(x.compareTo(y)) == -signum(y.compareTo(x))` for all `x` and `y`. (This implies that `x.compareTo(y)` must throw an exception if and only if `y.compareTo(x)` throws an exception.) The implementor must also ensure that the relation is transitive: `(x.compareTo(y) > 0 && y.compareTo(z) > 0)` implies `x.compareTo(z) > 0`. Finally, the implementor must ensure that `x.compareTo(y)==0` implies that `signum(x.compareTo(z)) == signum(y.compareTo(z))`, for all `z`. Parameters o:Version the object to be compared. Returns:int a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object. Annotations @Override Since 19.3

public int compareTo(Version o)

Implements java.lang.Comparable.compareTo.

Doc from java.lang.Comparable.compareTo.

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

The implementor must ensure signum(x.compareTo(y)) == -signum(y.compareTo(x)) for all x and y. (This implies that x.compareTo(y) must throw an exception if and only if y.compareTo(x) throws an exception.)

The implementor must also ensure that the relation is transitive: (x.compareTo(y) > 0 && y.compareTo(z) > 0) implies x.compareTo(z) > 0.

Finally, the implementor must ensure that x.compareTo(y)==0 implies that signum(x.compareTo(z)) == signum(y.compareTo(z)), for all z.

Parameters

o:Version: the object to be compared.

Returns:int

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

compareTo back to summary

compareTo	back to summary
public int compareTo(int... compareVersions) Implements java.lang.Comparable.compareTo. Compares this version to another GraalVM version. This is equivalent to using: `compareTo(Version.create(compareVersions))`. Parameters compareVersions:int[] Doc from java.lang.Comparable.compareTo. the object to be compared. Returns:int Doc from java.lang.Comparable.compareTo. a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object. Since 19.3

public int compareTo(int... compareVersions)

Implements java.lang.Comparable.compareTo.

Compares this version to another GraalVM version. This is equivalent to using: compareTo(Version.create(compareVersions)).

Parameters

compareVersions:int[]

equals back to summary

equals	back to summary
public boolean equals(Object obj) Overrides java.lang.Object.equals. Doc from java.lang.Object.equals. Indicates whether some other object is "equal to" this one. The `equals` method implements an equivalence relation on non-null object references: It is reflexive: for any non-null reference value `x`, `x.equals(x)` should return `true`. It is symmetric: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`. It is transitive: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`. It is consistent: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified. For any non-null reference value `x`, `x.equals(null)` should return `false`. An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes. Parameters obj:Object the reference object with which to compare. Returns:boolean `true` if this object is the same as the obj argument; `false` otherwise. Annotations @Override Since 19.3

public boolean equals(Object obj)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

It is reflexive: for any non-null reference value x, x.equals(x) should return true.
It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters

obj:Object: the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

format back to summary

format	back to summary
public String format(String format) Format the GraalVM version with a custom format string. The format string can contain any of the standard conversions of `java.util.Formatter`. At least four version components (possibly zero) are available as formatter arguments. In addition to the standard conversions, these special conversions are available: `"%[R...]"` includes a given part only if `isRelease` `"%[S...]"` includes a given part only if `isSnapshot` `"%[<digit>...]"` includes a given part only if the version contains at least `<digit>` non-zero version components (`<digit>` can be 0 to 9) Examples: Version.parse("22.3.0.1").format("%d.%d"); // returns "22.3" Version.parse("22.3.0.1").format("%4$d"); // returns "1" Version.parse("22.3.0.1").format("%[R%d.%d]%[Sdev]"); // returns "22.3" Version.parse("22.3.0.1").format("%[2XX]"); // returns "XX" Version.parse("23.0-dev").format("%3$d"); // returns "0" Version.parse("23.0-dev").format("%[R%d.%d]%[Sdev]"); // returns "dev" Version.parse("23.0-dev").format("%[2XX]"); // returns "" Since 23.0

public String format(String format)

Format the GraalVM version with a custom format string.

The format string can contain any of the standard conversions of java.util.Formatter. At least four version components (possibly zero) are available as formatter arguments.

In addition to the standard conversions, these special conversions are available:

"%[R...]" includes a given part only if isRelease
"%[S...]" includes a given part only if isSnapshot
"%[<digit>...]" includes a given part only if the version contains at least <digit> non-zero version components (<digit> can be 0 to 9)

Examples:

Version.parse("22.3.0.1").format("%d.%d"); // returns "22.3"
Version.parse("22.3.0.1").format("%4$d"); // returns "1"
Version.parse("22.3.0.1").format("%[R%d.%d]%[Sdev]"); // returns "22.3"
Version.parse("22.3.0.1").format("%[2XX]"); // returns "XX"
Version.parse("23.0-dev").format("%3$d"); // returns "0"
Version.parse("23.0-dev").format("%[R%d.%d]%[Sdev]"); // returns "dev"
Version.parse("23.0-dev").format("%[2XX]"); // returns ""

hashCode back to summary

hashCode	back to summary
public int hashCode() Overrides java.lang.Object.hashCode. Doc from java.lang.Object.hashCode. Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by `java.util.HashMap`. The general contract of `hashCode` is: Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. If two objects are equal according to the `equals` method, then calling the `hashCode` method on each of the two objects must produce the same integer result. It is not required that if two objects are unequal according to the `equals` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables. Returns:int a hash code value for this object Annotations @Override Since 19.3
