     * #### modifiers  
     public [Set](../../../java/util/Set.html "interface in java.util")<[ModuleDescriptor.Exports.Modifier](../../../java/lang/module/ModuleDescriptor.Exports.Modifier.html "enum in java.lang.module")> modifiers​()  
     Returns the set of modifiers.  
     Returns:  
     A possibly-empty unmodifiable set of modifiers  
     * #### isQualified  
     public boolean isQualified​()  
     Returns `true` if this is a qualified export.  
     Returns:  
     `true` if this is a qualified export  
     * #### source  
     public [String](../../../java/lang/String.html "class in java.lang") source​()  
     Returns the package name.  
     Returns:  
     The package name  
     * #### targets  
     public [Set](../../../java/util/Set.html "interface in java.util")<[String](../../../java/lang/String.html "class in java.lang")> targets​()  
     For a qualified export, returns the non-empty and immutable set of the module names to which the package is exported. For an unqualified export, returns an empty set.  
     Returns:  
     The set of target module names or for an unqualified export, an empty set  
     * #### compareTo  
     public int compareTo​([ModuleDescriptor.Exports](../../../java/lang/module/ModuleDescriptor.Exports.html "class in java.lang.module") that)  
     Compares this module export to another.  
      Two `Exports` 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](../../../java/lang/module/ModuleDescriptor.html#compareTo-java.lang.module.ModuleDescriptor-)). 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](../../../java/lang/Comparable.html#compareTo-T-)` in interface `[Comparable](../../../java/lang/Comparable.html "interface in java.lang")<[ModuleDescriptor.Exports](../../../java/lang/module/ModuleDescriptor.Exports.html "class in java.lang.module")>`  
     Parameters:  
     `that` \- The module export to compare  
     Returns:  
     A negative integer, zero, or a positive integer if this module export is less than, equal to, or greater than the given export dependence  
     * #### hashCode  
     public int hashCode​()  
     Computes a hash code for this module export.  
      The hash code is based upon the modifiers, the package name, and for a qualified export, the set of modules names to which the package is exported. It satisfies the general contract of the[Object.hashCode](../../../java/lang/Object.html#hashCode--) method.  
     Overrides:  
     `[hashCode](../../../java/lang/Object.html#hashCode--)` in class `[Object](../../../java/lang/Object.html "class in java.lang")`  
     Returns:  
     The hash-code value for this module export  
     See Also:  
     [Object.equals(java.lang.Object)](../../../java/lang/Object.html#equals-java.lang.Object-), [System.identityHashCode(java.lang.Object)](../../../java/lang/System.html#identityHashCode-java.lang.Object-)  
     * #### equals  
     public boolean equals​([Object](../../../java/lang/Object.html "class in java.lang") ob)  
     Tests this module export for equality with the given object.  
      If the given object is not an `Exports` then this method returns `false`. Two module exports 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](../../../java/lang/Object.html#equals-java.lang.Object-) method.  
     Overrides:  
     `[equals](../../../java/lang/Object.html#equals-java.lang.Object-)` in class `[Object](../../../java/lang/Object.html "class in java.lang")`  
     Parameters:  
     `ob` \- the object to which this object is to be compared  
     Returns:  
     `true` if, and only if, the given object is a module dependence that is equal to this module dependence  
     See Also:  
     [Object.hashCode()](../../../java/lang/Object.html#hashCode--), [HashMap](../../../java/util/HashMap.html "class in java.util")  
     * #### toString  
     public [String](../../../java/lang/String.html "class in java.lang") toString​()  
     Returns a string describing the exported package.  
     Overrides:  
     `[toString](../../../java/lang/Object.html#toString--)` in class `[Object](../../../java/lang/Object.html "class in java.lang")`  
     Returns:  
     A string describing the exported package
