DependencyConstraintConfiguration

public interface DependencyConstraintConfiguration

Value container about the dependency resolution constraints that should can be to filter bundle dependencies.

This interface specifies the constraint values that can be used to specify the environment for bundle loading and dependency resolution. The enclosed values will be used to filter out or otherwise determine if a bundle dependency should be used or omitted.

Instances of this interface can be compared by equality and be serialized.

This interface is not to be implemented by clients.

Use the builder() methods to create a new instance.

public static Builder builder()

Creates a new builder without any constraints specified.

The new builder.

public static Builder builder(DependencyConstraintConfiguration copy) throws NullPointerException

copyThe constraints to copy from.

The new builder.

NullPointerExceptionIf the argument is null.

public abstract boolean equals(Object obj)

Overridden from: Object

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

It is reflexive: for any non-null reference value x, x.equals(x) should return true.
It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

objthe reference object with which to compare.

true if this object is the same as the obj argument; false otherwise.

public abstract int hashCode()

Overridden from: Object

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
It is not required that if two objects are unequal according to the Object.equals(Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)
