- All Implemented Interfaces:
Comparable<ModuleDescriptor.Opens>
- Enclosing class:
ModuleDescriptor
A package opened by a module, may be qualified or unqualified.
The opens directive in a module declaration declares a package to be open to allow all types in the package, and all their members, not just public types and their public members to be reflected on by APIs that support private access or a way to bypass or suppress default Java language access control checks.

compareTo
Compares this moduleOpens
to another.Two
Opens
objects are compared by comparing the package names lexicographically. Where the packages names are equal then the sets of modifiers are compared in the same way that module modifiers are compared (seeModuleDescriptor.compareTo
). Where the package names are equal and the set of modifiers are equal then the set of target modules are compared. This is done by sorting the names of the target modules in ascending order, and according to their natural ordering, and then comparing the corresponding elements lexicographically. Where the sets differ in size, and the larger set contains all elements of the smaller set, then the larger set is considered to succeed the smaller set.- Specified by:
compareTo
in interfaceComparable<ModuleDescriptor.Opens>
- Parameters:
that
- The moduleOpens
to compare- Returns:
- A negative integer, zero, or a positive integer if this module
Opens
is less than, equal to, or greater than the given moduleOpens
-
hashCode
public int hashCode()Computes a hash code for this moduleOpens
.The hash code is based upon the modifiers, the package name, and for a qualified
Opens
, the set of modules names to which the package is opened. It satisfies the general contract of theObject.hashCode
method. -
equals
Tests this moduleOpens
for equality with the given object.If the given object is not an
Opens
then this method returnsfalse
. TwoOpens
objects are equal if their set of modifiers is equal, the package names are equal and the set of target module names is equal.This method satisfies the general contract of the
Object.equals
method. -
