- Comparable<ModuleDescriptor.Opens>
 - Enclosing class:
- 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. - Since:

Method Detail- 
modifierspublic Set<ModuleDescriptor.Opens.Modifier> modifiers() Returns the set of modifiers.- Returns:
- A possibly-empty unmodifiable set of modifiers
 
 - 
isQualifiedpublic boolean isQualified() Returnstrueif this is a qualified opens.- Returns:
- trueif this is a qualified opens
 
 - 
sourcepublic String source() Returns the package name.- Returns:
- The package name
 
 - 
targetspublic Set<String> targets() For a qualified opens, returns the non-empty and immutable set of the module names to which the package is open. For an unqualified opens, returns an empty set.- Returns:
- The set of target module names or for an unqualified opens, an empty set
 
 - 
compareTopublic int compareTo(ModuleDescriptor.Opens that) Compares this module opens to another.Two Opensobjects 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:
- compareToin interface- Comparable<ModuleDescriptor.Opens>
- Parameters:
- that- The module opens 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 module opens
 
 - 
hashCodepublic int hashCode() Computes a hash code for this module 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.hashCodemethod.- Overrides:
- hashCodein class- Object
- Returns:
- The hash-code value for this module opens
- See Also:
- Object.equals(java.lang.Object),- System.identityHashCode(java.lang.Object)
 
 - 
equalspublic boolean equals(Object ob) Tests this module opens for equality with the given object.If the given object is not an Opensthen this method returnsfalse. TwoOpensobjects 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.equalsmethod.- Overrides:
- equalsin class- Object
- Parameters:
- ob- the object to which this object is to be compared
- Returns:
- trueif, and only if, the given object is a module dependence that is equal to this module dependence

- Object.hashCode(),- HashMap
