Returns:

A converter that first applies this converter and then other.

fromNameFunction

static AttributeNameConverter fromNameFunction(UnaryOperator<String> function)

Creates a new AttributeNameConverter from a name converter function.

Conversion is independent of element.

Parameters:

function - The function used to convert attribute names.

Returns:

A new AttributeValueConverter from function.

Throws:

IllegalArgumentException - When function is null.

fromNameMap

static AttributeNameConverter fromNameMap(Map<String,String> map)
