Interface BreadcrumbContextI<T extends BreadcrumbContextI<T,U>,U extends BOI>

Type Parameters:

T - The type of the context object itself.

U - The base type of the business object associated with the context.

All Known Subinterfaces:

FormContextI

All Known Implementing Classes:

DefaultFormContext

public interface BreadcrumbContextI<T extends BreadcrumbContextI<T,U>,U extends BOI>

A core, internal-only interface for any object that acts as a "breadcrumb" context in a hierarchical chain.

This interface defines the fundamental traversal methods and provides default implementations for finding business objects by walking up the context chain.

Method Summary

Modifier and Type	Method and Description
default U	findFirstBO() Finds the first business object of any parent context in the chain, returning the value directly.
default <V extends U> V	findFirstBOOfType(java.lang.Class<V> objectType) Finds the first business object of a specific type in the parent context chain, returning the value directly.
default U	findFirstBOWhere(java.util.function.Predicate<U> predicate) Finds the first business object of any parent context that fulfills a given predicate, returning the value directly.
default U	findParentBO() Finds the business object of the immediate parent context, returning the value directly.
U	getContextBO() Gets the associated business object for this specific context, returning the value directly.
T	getParentBreadcrumbContext() Gets the parent context of the current context, returning the value directly.

Method Detail

getParentBreadcrumbContext

T getParentBreadcrumbContext()

Gets the parent context of the current context, returning the value directly.

Returns:

The parent context, or null if there is no parent.

getContextBO

U getContextBO()

Gets the associated business object for this specific context, returning the value directly.

Returns:

The associated business object, or null if this context has no business object.

findParentBO

default U findParentBO()

Finds the business object of the immediate parent context, returning the value directly.

This is a convenience default method that walks one step up the chain.

Returns:

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

findFirstBO

default U findFirstBO()

Finds the first business object of any parent context in the chain, returning the value directly.

This is a convenience default method that finds the first non-null business object in the parent chain.

Returns:

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

findFirstBOOfType

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

Finds the first business object of a specific type in the parent context chain, returning the value directly.

This is a convenience default method that walks the chain and casts the first matching object.

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

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

Finds the first business object of any parent context that fulfills a given predicate, returning the value directly.

This is the core traversal logic that walks up the breadcrumb chain.

Parameters:

predicate - A Predicate to test the business object.

Returns:

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