Class SerializableLazyValue<T extends Serializable>

java.lang.Object

org.mule.runtime.api.util.LazyValue<T>

org.mule.runtime.api.util.SerializableLazyValue<T>

All Implemented Interfaces:

Serializable, Supplier<T>

public class SerializableLazyValue<T extends Serializable>
extends LazyValue<T>
implements Serializable

Implementation of LazyValue that adds logic for serialization. In order to work properly, values must implement the Serializable interface.

While serializing, if the value was not yet resolved, it will be. As a consequence, LazyValue.isComputed() will return different values before and after serialization.

Since:

1.2.0

Method Detail

get

public T get()

Description copied from class: LazyValue

Returns the lazy value. If the value has not yet been computed, then it does so

Specified by:

get in interface Supplier<T extends Serializable>

Overrides:

get in class LazyValue<T extends Serializable>

Returns:

the lazy value

flatMap

public <R> R flatMap(Function<T,R> function)

Description copied from class: LazyValue

Applies the given function through the output of LazyValue.get(). If the value has not already been computed, this method will trigger computation. This method is thread-safe.

Overrides:

flatMap in class LazyValue<T extends Serializable>

Type Parameters:

R - the generic type of the function's output

Parameters:

function - a transformation function

Returns:

a transformed value
