Method Detail

modifiers

public Set<ModuleDescriptor.Requires.Modifier> modifiers()

Returns the set of modifiers.

Returns:

A possibly-empty unmodifiable set of modifiers

name

public String name()

Return the module name.

Returns:

The module name

compareTo

public int compareTo(ModuleDescriptor.Requires that)

Compares this module dependence to another.

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.

Specified by:

compareTo in interface Comparable<ModuleDescriptor.Requires>

Parameters:

that - the object to be compared.

Returns:

A negative integer, zero, or a positive integer if this module dependence is less than, equal to, or greater than the given module dependence

equals

public boolean equals(Object ob)

Tests this module dependence for equality with the given object.

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 and set of modifiers are equal.

This method satisfies the general contract of the Object.equals method.

Overrides:

equals in class Object

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

Object.hashCode(), HashMap

hashCode

public int hashCode()

Computes a hash code for this module dependence.

The hash code is based upon the module name and modifiers. It satisfies the general contract of the Object.hashCode method.

Overrides:

hashCode in class Object

Returns:

The hash-code value for this module dependence

See Also:

Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

toString

public String toString()

Returns a string describing module dependence.

Overrides:

toString in class Object

Returns:

A string describing module dependence
