Method Detail

service

public String service()

Returns the fully qualified class name of the service type.

Returns:
The fully qualified class name of the service type

providers

public List<String> providers()

Returns the list of the fully qualified class names of the providers or provider factories.

Returns:
A non-empty and unmodifiable list of the fully qualified class names of the providers or provider factories

compareTo

public int compareTo​(ModuleDescriptor.Provides that)

Compares this provides to another.

Two Provides objects are compared by comparing the fully qualified class name of the service type lexicographically. Where the class names are equal then the list of the provider class names are compared by comparing the corresponding elements of both lists lexicographically and in sequence. Where the lists differ in size, N is the size of the shorter list, and the first N corresponding elements are equal, then the longer list is considered to succeed the shorter list.

Specified by:
compareTo in interface Comparable<ModuleDescriptor.Provides>
Parameters:
that - The Provides to compare
Returns:
A negative integer, zero, or a positive integer if this provides is less than, equal to, or greater than the given provides

hashCode

public int hashCode()

Computes a hash code for this provides.

The hash code is based upon the service type and the set of providers. It satisfies the general contract of the Object.hashCode method.

Overrides:
hashCode in class Object
Returns:
The hash-code value for this module provides

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

equals

public boolean equals​(Object ob)

Tests this provides for equality with the given object.

If the given object is not a Provides then this method returns false. Two Provides objects are equal if the service type is equal and the list of providers is 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 Provides that is equal to this Provides

Object.hashCode(), HashMap

toString

public String toString()

Returns a string describing this provides.

Overrides:
toString in class Object
Returns:
A string describing this provides
