Method Detail
modifiers
public Set<ModuleDescriptor.Exports.Modifier> 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 source()
Returns the package name.
- Returns:
- The package name
targets
public Set<String> 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 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
). 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.Exports>
- 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
method.
- Overrides:
-
hashCode
in classObject
- Returns:
- The hash-code value for this module export
- See Also:

Object.equals(java.lang.Object)
,System.identityHashCode(java.lang.Object)
equals
public boolean equals(Object 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
method.
- Overrides:
-
equals
in classObject
- 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()
,HashMap
toString
public String toString()
Returns a string describing the exported package.
