Method Summary

Modifier and Type	Method	Description
<T> T	apply(T instance)	Applies the configured injections to the given instance.
Injections	modify(String name, Consumer<Object> modifier, boolean preferGetter)	Allows in-place modification of a value reference from the target instance.
Injections	set(Class<?> type, Object value, boolean setter)	Injects a value into the setters setting the specified type - if a setter does not exist, it will try to inject directly into a field of the type.
Injections	set(String name, Object value, boolean preferSetter)	If preferSetter is true, an attempt will be made to inject the value using a setter method for the named property, otherwise the field itself will be injected.
Injections	update(String name, Function<Object,Object> updater, boolean preferSetter, boolean preferGetter)	Updates a field value by applying given function to the current value.

public InjectionsImpl()

Method Details

set

public Injections set(String name,
 Object value,
 boolean preferSetter)

Description copied from interface: Injections

If preferSetter is true, an attempt will be made to inject the value using a setter method for the named property, otherwise the field itself will be injected. If the preferSetter value is false the field will be directly injected.

Specified by:

set in interface Injections

Parameters:

name - the name of the property or field

value - the value (may be a Randomizer).

preferSetter - whether to prefer the setter over direct injection

Returns:

the configured Injections instance

set

public Injections set(Class<?> type,
 Object value,
 boolean setter)

Description copied from interface: Injections

Injects a value into the setters setting the specified type - if a setter does not exist, it will try to inject directly into a field of the type. If a setter and a field both match, it will only inject one of them, not both.

Specified by:

set in interface Injections

Parameters:

type - the field type

value - the value to inject

setter - prefers using the setter if it exists

Returns:

the configured injections instance

update

public Injections update(String name,
 Function<Object,Object> updater,
 boolean preferSetter,
 boolean preferGetter)

Description copied from interface: Injections

Updates a field value by applying given function to the current value. If the preferProps parameter is true, the injector will first attempt to use the named property before defaulting update the field directly.

If the updater function returns a Randomizer, it will be used to generate the updated value.

Specified by:

update in interface Injections

Parameters:

name - the property or field name

updater - the updater function

preferSetter - will try to use the setter rather than go directly to the field

preferGetter - will try to use the getter rather than go directly to the field

Returns:

the instance to the Injections implementation

modify

public Injections modify(String name,
 Consumer<Object> modifier,
 boolean preferGetter)

Description copied from interface: Injections

Allows in-place modification of a value reference from the target instance. The target instance will be passed to the provided consumer for modification.

Specified by:

modify in interface Injections

Parameters:

name - the name

modifier - the modifier

preferGetter - will try to use the getter rather than going directly to the field

Returns:

the instance of the Injections implementation

apply

public <T> T apply(T instance)
            throws ReflectiveOperationException

Applies the configured injections to the given instance.

Type Parameters:

T - the type of the target instance

Parameters:

instance - the target instance

Returns:

the updated instance (reference to the incoming instance)

Throws:

ReflectiveOperationException - if there is a problem injecting
