Method Detail

toType

@Nonnull
public static Injectable toType(Object value,
                                          Type type)

Attempts to cast the given value to the provided Type. Designed for use with Sling injectors

Parameters:

value - An arbitrary value

type - A Type reference. Usually reflects the type of Java class member

Returns:

A Injectable instance containing the transformed value; can contain null if type casting was not possible

toType

@Nonnull
public static Injectable toType(Object value,
                                          Type type,
                                          BiFunction<Object,Type,Object> converter)

Attempts to cast the given value to the provided Type. Designed for use with Sling injectors

Parameters:

value - An arbitrary value

type - A Type reference. Usually reflects the type of Java class member

converter - A function that we use to convert a single entry of the provided value into the given type. Considering the given value is an array or collection, the converter must process every separate array's (collection's) element. If the given value is a singleton object or primitive, the converter processes it as is

Returns:

A Injectable instance containing the transformed value; can contain null if type casting was not possible
