Class StreamParametersMapFunction<T>

java.lang.Object

ch.powerunit.helpers.StreamParametersMapFunction<T>

Type Parameters:

T - the input type

All Implemented Interfaces:

Function<T[],Object[]>

public final class StreamParametersMapFunction<T>
extends Object
implements Function<T[],Object[]>

This is a class that provide a way to transform stream of String to Object based on the @Parameter field type.

Access to this class is available from the TestSuite interface.

Method Detail

apply

public Object[] apply(T[] input)

Specified by:

apply in interface Function<T[],Object[]>

map

public static <T,R> StreamParametersMapFunction<T> map(int idx,
                                                       Function<T,R> mapFunction)

Start building a Parameter Mapper function, with an initial converter.

Not specified index are considered transformed by identity function.

Type Parameters:

T - The input type for the function

R - the result type for the function

Parameters:

idx - The parameter index

mapFunction - the function to be applied

Returns:

the function on the parameter array

stringToParameterMap

public static StreamParametersMapFunction<String> stringToParameterMap(Class<?> testClass)

Start building a Parameter Mapper function, assuming that the input are String, and using the type of the @Parameter field.

Fields not supported will not be mapped and must be handled manually, using andMap method.

Parameters:

testClass - the testClass with the annotation

Returns:

the function on the parameter array

Supported automated conversion

andMap

public <R> StreamParametersMapFunction<T> andMap(int idx,
                                                 Function<T,R> mapFunction)

Defines an additional Parameter Mapper function.

Not specified index are considered transformed by identity function.

Type Parameters:

R - The return type for the function

Parameters:

idx - The parameter index

mapFunction - the function to be applied

Returns:

the function on the parameter array

addFieldToEachEntry

public static <T> Function<Object[],Object[]> addFieldToEachEntry(T field)

Provide a way to add a field to head parameter line.

Type Parameters:

T - The object type to be added.

Parameters:

field - The field to be added.

Returns:

the function that can be used on the stream ( Stream.map(Function)).
