Method Detail

• <OUT> public static OUT convertItem(Object input, java.util.function.Function<Object, OUT> transformer)

  Converts an item using a specified transformer.

  The following type are recursively unfolded before conversion:

  • java.util.concurrent.Callable
  • java.util.Optional
  • Provider
  • java.util.function.Supplier

  Parameters:

  input - Object to convert

  transformer - Transformer. Is p-asses an unfolded value.

  Type Parameters:

  OUT - Type to convert to.

  Returns:

  Converted value. Never null.

  Throws:

  UnexpectedNullException or UnsupportedConfigurationException

• <OUT> public static OUT convertItemOrNull(Object input, java.util.function.Function<Object, OUT> transformer)

  Converts an item using a specified transformer.

  THe following types are recursively unfolded before conversion:

  • java.util.concurrent.Callable
  • java.util.Optional
  • Provider
  • java.util.function.Supplier
  Empty Provider and java.util.Optional instances are treated like nulls.

  Parameters:

  input - Object to convert

  transformer - Transformer. Is passed an unfolded value.

  Type Parameters:

  OUT - Type to convert to.

  Returns:

  Converted value or null.

  Throws:

  UnsupportedConfigurationException

• <OUT> public static java.util.Collection<OUT> convertItems(java.util.Collection<?> inputs, java.util.Collection<OUT> target, java.util.function.Function<Object, OUT> transformer)

  Converts a collection type using a specified transformer

  A number of non-iterable types are unfolded before conversion. See convertItems.

  Collections are flattened. Null values will raise exceptions.

  Parameters:

  inputs - Objects to convert.

  transformer - Transformer. Is passed an unfolded value.

  target - Collection to add to.

  Type Parameters:

  OUT - Type to convert to.

  Returns:

  List of converted values. Can be empty, but never null. Will contain no null values.

• <OUT> public static java.util.Collection<OUT> convertItemsDropNull(java.util.Collection<?> inputs, java.util.Collection<OUT> target, java.util.function.Function<Object, OUT> transformer)

  Converts a collection type using a specified transformer

  A number of non-iterable types are unfolded before conversion. See convertItems.

  Collections are flattened. Null values are dropped. Empty Provider and java.util.Optional instances are treated like nulls. A null collection will be dropped.

  Parameters:

  inputs - Objects to convert.

  transformer - Transformer. Is passed an unfolded value.

  target - Collection to add to.

  Type Parameters:

  OUT - Type to convert to.

  Returns:

  List of converted values. Can be empty, but never null. Will contain no null values.

  tx - Transformer

  Returns:

  Transformed list

• <I, O> public static java.util.Set<O> toSet(java.util.Collection<I> collection, java.util.function.Function<I, O> tx)

  Transforms a collection to a set.

  Parameters:

  collection - Input data

  Transformed set

• <I, O> public static java.util.Set<O> toSet(Iterable<I> collection, java.util.function.Function<I, O> tx)

  Transforms an iterable data set to a set.

  Parameters:

  collection - Input data

  tx - Transformer

  Returns:

  Transformed set
