eager back to summary

eager	back to summary
public static <T> Value<T> eager(final Value<T> delegate) Get a new eagerly initialized `value provider`. The value returned by its `get()` method is eagerly computed from the supplied `delegate` value provider and is then stored in a final field for a subsequent retrieval. The implementation of the returned eager value provider is thread-safe and is guaranteed to invoke the `get()` method on the supplied `delegate` value provider instance once and only once. If the supplied value provider is `null`, an `empty` value provider is returned. Parameters <T> value type. delegate:Value<T> value provider delegate that will be used to eagerly initialize the value provider. Returns:Value<T> eagerly initialized, constant value provider.

public static <T> Value<T> eager(final Value<T> delegate)

Get a new eagerly initialized value provider.

The value returned by its get() method is eagerly computed from the supplied delegate value provider and is then stored in a final field for a subsequent retrieval.

The implementation of the returned eager value provider is thread-safe and is guaranteed to invoke the get() method on the supplied delegate value provider instance once and only once.

If the supplied value provider is null, an empty value provider is returned.

lazy back to summary

lazy	back to summary
public static <T> LazyValue<T> lazy(final Value<T> delegate) Get a new lazily initialized `value provider`. The value returned by its `get()` method is lazily retrieved during a first call to the method from the supplied `delegate` value provider and is then cached for a subsequent retrieval. The implementation of the returned lazy value provider is thread-safe and is guaranteed to invoke the `get()` method on the supplied `delegate` value provider instance at most once. If the supplied value provider is `null`, an `empty` value provider is returned. Parameters <T> value type. delegate:Value<T> value provider delegate that will be used to lazily initialize the value provider. Returns:LazyValue<T> lazily initialized value provider.

The implementation of the returned lazy value provider is thread-safe and is guaranteed to invoke the get() method on the supplied delegate value provider instance at most once.

If the supplied value provider is null, an empty value provider is returned.

Parameters

lazily initialized value provider.

of back to summary

of	back to summary
public static <T> Value<T> of(final T value) Get a new constant `value provider` whose `get()` method always returns the instance supplied to the `value` parameter. In case the supplied value constant is `null`, an `empty` value provider is returned. Parameters <T> value type. value:T value instance to be provided. Returns:Value<T> constant value provider.

public static <T> Value<T> of(final T value)

Get a new constant value provider whose get() method always returns the instance supplied to the value parameter.

In case the supplied value constant is null, an empty value provider is returned.

Parameters

<T>: value type.
value:T: value instance to be provided.

Returns:Value<T>

constant value provider.

equals back to summary

equals	back to summary
public boolean equals(final Object o) 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 o:Object the reference object with which to compare. Returns:boolean `true` if this object is the same as the obj argument; `false` otherwise. Annotations @Override

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

o:Object: the reference object with which to compare.

Returns:boolean

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

hashCode	back to summary
public int hashCode() Overrides java.lang.Object.hashCode. Doc from java.lang.Object.hashCode. Returns a hash code value for this 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 Annotations @Override
