Class StringMapCompositor

  • All Implemented Interfaces:
    ValuesArrayBinder<StringMapCompositor,​java.lang.String>
    public class StringMapCompositor
extends java.lang.Object
implements ValuesArrayBinder<StringMapCompositor,​java.lang.String>
    StringCompositor provides a way to build strings from a string template and provided values.

    The template is simply an array of string values, where odd indices represent literals, and even indices represent token positions. If the token positions contains words, then these can be used as keys for looking up values in an associated map. If not, then values are simply positional, in which case simple numerals are used as indices for debugging purposes, although they are not referenced during string interpolation.
