Tests this module dependence for equality with the given object.

Computes a hash code for this module dependence.
|
Set<ModuleDescriptor.Requires.Modifier> |

public int compareTo(ModuleDescriptor.Requires that)
Two Requires
objects are compared by comparing their
module name lexicographically. Where the module names are equal then
the sets of modifiers are compared based on a value computed from the
ordinal of each modifier. Where the module names are equal and the
set of modifiers are equal then the version of the modules recorded
at compile-time are compared. When comparing the versions recorded
at compile-time then a dependence that has a recorded version is
considered to succeed a dependence that does not have a recorded
version.
compareTo
in interface Comparable<ModuleDescriptor.Requires>
that
- the object to be compared.public boolean equals(Object ob)
If the given object is not a Requires
then this method
returns false
. Two module dependence objects are equal if
the module names are equal, set of modifiers are equal, and the
compiled version of both modules is equal or not recorded for
both modules.
This method satisfies the general contract of the Object.equals
method.

public int hashCode()
The hash code is based upon the module name, modifiers, and the
module version if recorded at compile time. It satisfies the general
contract of the Object.hashCode
method.
