Method Detail

with

public L with(Check<? super D> check)

Description copied from interface: CheckDsl

Add check of the root object to the

Specified by:

with in interface CheckDsl<L,D>

Parameters:

check - Additional check to add to the general logical and.

Returns:

The fluent DSL allowing further building of the check.

withField

public <V> TransformationBuilder<V,L> withField(String name,
                                                Transformation<? super D,V> transformation)

Description copied from interface: CheckDsl

Add a check of a transformed value, e.g. field access.

Specified by:

withField in interface CheckDsl<L,D>

Type Parameters:

V - Type of the transformed value.

Parameters:

name - Name of the transformation / field

transformation - Transformation function to apply in order to check the result.

Returns:

The fluent DSL allowing further building of the check.

withField

public <V> TransformationBuilder<V,L> withField(Transformation<? super D,V> transformation)

Description copied from interface: CheckDsl

Add a check of a transformed value, e.g. field access. This variant will try to "guess" the name of the transformation / field.

Specified by:

withField in interface CheckDsl<L,D>

Type Parameters:

V - Type of the transformed value.

Parameters:

transformation - Transformation function to apply in order to check the result.

Returns:

The fluent DSL allowing further building of the check.

or

public L or()

Description copied from interface: CheckDsl

Allow chaining of checks using logical or. Keep in mind that sequence of directly chained field checks are always evaluated with logical and. So e.g. check.withField(MyClass::getFirstName).equalTo("John").withField(MyClass::getLastName).equalTo("Doe") .or() .withField(MyClass::getFirstName).equalTo("Jane").withField(MyClass::getLastName).equalTo("Dee") evaluates as: (firstName == "John" and lastName == "Doe") or (firstName == "Jane" and lastName == "Dee")

Specified by:

or in interface CheckDsl<L,D>

Returns:

The fluent DSL allowing further building of the check.

evaluate

public Result evaluate(D data,
                       ResultFactory factory)

Description copied from interface: Check

Abstract method to delegate implementation of specific check logic to subclasses.

Specified by:

evaluate in interface Check<D>

Parameters:

data - Tested data.

factory - Result factory responsible for creating result tree from current node.

Returns:

representation of outcome of the test.

toString

public String toString()

Overrides:

toString in class Object
