Method Details

to

ValueOfOriginDestination to(TargetSelector destination)

Specifies the destination selector for the assignment.

Parameters:

destination - selector

Returns:

an assigment containing origin and destination selectors

Since:

to

<T,
R> ValueOfOriginDestination to(GetMethodSelector<T,R> destination)

Specifies the destination method reference for the assignment. This is a shorthand API of to(TargetSelector) allowing:

 to(field(Pojo::getValue))
 

to be specified as a slightly shorter version:

 to(Pojo::getValue)
 

Type Parameters:

T - type declaring the method

R - return type of the method

Parameters:

destination - method reference

Returns:

an assigment containing origin and destination selectors

Since:

3.0.0

generate

<T> Assignment generate(GeneratorSpecProvider<T> gen)

T - the type of object to generate

Parameters:

gen - provider of customisable built-in generators (also known as specs)

generate

<T> Assignment generate(GeneratorSpec<T> spec)

Generates values using arbitrary generator specs.

This method provides the same functionality as the top-level API: InstancioApi.generate(TargetSelector, GeneratorSpec)

Type Parameters:

T - the type of object to generate

Parameters:

spec - generator spec for generating values

set

<T> Assignment set(T value)

Sets a value to matching selector targets.

This method provides the same functionality as the top-level API: InstancioApi.set(TargetSelector, Object)

Type Parameters:

T - the type of object to set

Parameters:

value - value to set

Returns:

an assignment

Since:

3.0.0

supply

<T> Assignment supply(Generator<T> generator)

Supplies an object using a Generator to matching selector targets.

This method provides the same functionality as the top-level API: InstancioApi.supply(TargetSelector, Generator)

Type Parameters:

T - the type of object to generate

Parameters:

generator - for generating values

Returns:

an assignment
