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 interfaceComparable<ModuleDescriptor.Provides>
- Parameters:
-
that
- TheProvides
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 classObject
- Returns:
- The hash-code value for this module provides
- See Also:

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 classObject
- Parameters:
-
ob
- the object to which this object is to be compared - Returns:
-
true
if, and only if, the given object is aProvides
that is equal to thisProvides

,HashMap
toString
public String toString()
Returns a string describing this provides.
