Class Builder<B,R>

java.lang.Object

org.swblocks.jbl.builders.Builder<B,R>

public final class Builder<B,R>
extends java.lang.Object

Generic Builder class to define a creator and build operations to apply to the created object. Then a Predicate validator to validate buildFn function before constructing the result.

The class is typed with two generic types. B the domain buildFn class. R the domain results class generated from the domain buildFn.

Method Summary

Modifier and Type	Method and Description
R	build() Creates the domain buildFn, applies all the operations defined and then generates the domain results class.
static <B,R> Builder<B,R>	instanceOf(java.util.function.Supplier<B> creator, java.util.function.Function<B,R> builder) Creates an instance of the Builder given creater and buildFn functions.
static <B,R> Builder<B,R>	instanceOf(java.util.function.Supplier<B> creator, java.util.function.Predicate<B> validator, java.util.function.Function<B,R> builder) Creates an instance of the Builder given creater, validator and buildFn functions.
<U> Builder<B,R>	with(java.util.function.BiConsumer<B,U> consumer, U value) Defines an operation and value to be applied to the domain buildFn class.

Method Detail

instanceOf

public static <B,R> Builder<B,R> instanceOf(java.util.function.Supplier<B> creator,
                                            java.util.function.Function<B,R> builder)

Creates an instance of the Builder given creater and buildFn functions. Validation defaults to always true.

Type Parameters:

B - domain buildFn class

R - domain results class

Parameters:

creator - Supplier to generate the domain buildFn class.

builder - Function to generate the domain results class from the domain buildFn class.

Returns:

Created Builder object

instanceOf

public static <B,R> Builder<B,R> instanceOf(java.util.function.Supplier<B> creator,
                                            java.util.function.Predicate<B> validator,
                                            java.util.function.Function<B,R> builder)

Creates an instance of the Builder given creater, validator and buildFn functions.

Type Parameters:

B - domain buildFn class

R - domain results class

Parameters:

creator - Supplier to generate the domain buildFn class.

validator - Predicate to validate the domain buildFn class.

builder - Function to generate the domain results class from the domain buildFn class.

Returns:

Created Builder object

with

public <U> Builder<B,R> with(java.util.function.BiConsumer<B,U> consumer,
                             U value)

Defines an operation and value to be applied to the domain buildFn class.

Type Parameters:

U - Type of value

Parameters:

consumer - consumer method

value - Value to be applied to the consumer

Returns:

this class for chaining methods.

build

public R build()

Creates the domain buildFn, applies all the operations defined and then generates the domain results class.

Returns:

domain results class built from the domain buildFn class
