Interface BreadcrumbFinderI<U extends BOI>

Type Parameters:

U - The base type of the business object to be found.

All Known Implementing Classes:

DefaultBreadcrumbFinder

public interface BreadcrumbFinderI<U extends BOI>

A public-facing interface for finding business objects by walking up a context chain.

This API is designed to be used by clients and is completely decoupled from the internal context objects used for traversal.

Method Summary

Modifier and Type	Method and Description
java.util.Optional<U>	findFirst() Finds the first business object of any parent context in the chain.
U	findFirstBO() Finds the first business object of any parent context in the chain.
<V extends U> V	findFirstBOOfType(java.lang.Class<V> objectType) Finds the first business object of a specific type in the parent context chain.
U	findFirstBOWhere(java.util.function.Predicate<U> predicate) Finds the first business object of any parent context that fulfills a given predicate.
<V extends U> java.util.Optional<V>	findFirstOfType(java.lang.Class<V> objectType) Finds the first business object of a specific type in the parent context chain.
java.util.Optional<U>	findFirstWhere(java.util.function.Predicate<U> predicate) Finds the first business object of any parent context that fulfills a given predicate.
java.util.Optional<U>	findParent() Finds the business object of the immediate parent context.
U	findParentBO() Finds the business object of the immediate parent context.

Method Detail

findParent

java.util.Optional<U> findParent()

Finds the business object of the immediate parent context.

Returns:

An Optional containing the parent's business object, or empty if not found.

findFirst

java.util.Optional<U> findFirst()

Finds the first business object of any parent context in the chain.

Returns:

An Optional containing the first found business object, or empty if none are found.

findFirstOfType

<V extends U> java.util.Optional<V> findFirstOfType(java.lang.Class<V> objectType)

Finds the first business object of a specific type in the parent context chain.

Type Parameters:

V - The specific type of the object.

Parameters:

objectType - The Class of the business object you are looking for.

Returns:

An Optional containing the first found business object of the specified type.

findFirstWhere

java.util.Optional<U> findFirstWhere(java.util.function.Predicate<U> predicate)

Finds the first business object of any parent context that fulfills a given predicate.

Parameters:

predicate - A Predicate to test the business object.

Returns:

An Optional containing the first business object that satisfies the predicate.

findParentBO

U findParentBO()

Finds the business object of the immediate parent context.

Returns:

The parent's business object, or null if not found.

findFirstBO

U findFirstBO()

Finds the first business object of any parent context in the chain.

Returns:

The first found business object, or null if none are found.

findFirstBOOfType

<V extends U> V findFirstBOOfType(java.lang.Class<V> objectType)

Finds the first business object of a specific type in the parent context chain.

Type Parameters:

V - The specific type of the object.

Parameters:

objectType - The Class of the business object you are looking for.

Returns:

The first found business object of the specified type, or null if not found.

findFirstBOWhere

U findFirstBOWhere(java.util.function.Predicate<U> predicate)

Finds the first business object of any parent context that fulfills a given predicate.

Parameters:

predicate - A Predicate to test the business object.

Returns:

The first business object that satisfies the predicate, or null if not found.
