Comparable<ModuleDescriptor.Opens>
ModuleDescriptor
public static final class ModuleDescriptor.Opens extends Object implements Comparable<ModuleDescriptor.Opens>
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.

Set |
accessFlags() |
Returns the set of the module opens flags. |
int |
compareTo |
Compares this module Opens to another. |
boolean |
equals |
Tests this module Opens for equality with the given object. |
int |
hashCode() |
Computes a hash code for this module Opens . |
boolean |
isQualified() |
Returns true if this is a qualified Opens . |
Set |
modifiers() |
Returns the set of modifiers. |
String |
source() |
Returns the package name. |
Set |

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 (see ModuleDescriptor.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.
compareTo
in interface Comparable<ModuleDescriptor.Opens>
that
- The module Opens
to compareOpens
is less than, equal to, or greater than the given module Opens
public int hashCode()
Opens
. 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 the Object.hashCode
method.
public boolean equals(Object ob)
Opens
for equality with the given object. If the given object is not an Opens
then this method returns false
. Two Opens
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.
