public final Class FactoryBuilder

extends Object
Class Inheritance
Imports
java.io.Serializable

A convenience class that defines generically typed static methods to aid in the building of Factory instances.

Factory is used by MutableConfiguration to avoid adding non-Serializable instances that would assume usage in the local JVM.

Two styles of builder are available:

Factory instances can also be created in other ways.

Method Detail

factoryOfback to summary
public static <T> Factory<T> factoryOf(Class<T> clazz)

Constructs a Factory that will produce factory instances of the specified class.

The specified class must have a no-args constructor.

Parameters

the class of instances to be produced by the returned Factory

Returns:Factory<T>

a Factory for the specified clazz

public static <T> Factory<T> factoryOf(String className)

Constructs a Factory that will produce factory instances of the specified class.

The specified class must have a no-args constructor.

Parameters
<T>
the type of the instances produced by the Factory
className:String

the class of instances to be produced by the returned Factory

Returns:Factory<T>

a Factory for the specified clazz

factoryOfback to summary
public static <T extends Serializable> Factory<T> factoryOf(T instance)

Constructs a Factory that will return the specified factory Serializable instance.

If T is not Serializable use factoryOf(Class) or factoryOf(String).

Parameters
<T>

instance:T

the Serializable instance the Factory will return

Returns:Factory<T>

a Factory for the instance

equalsback to summary
public boolean equals(Object other)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

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.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
other:Object

the reference object with which to compare.

Returns:boolean

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

@Override
hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by java.util.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 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 equals 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.
Returns:int

a hash code value for this object.
