Class StringCompositor

  • All Implemented Interfaces:
    ValuesBinder<StringCompositor,​java.lang.String>
    public class StringCompositor
extends java.lang.Object
implements ValuesBinder<StringCompositor,​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 token positions, and even indices represent literals. This version of the StringCompositor fetches data from the bindings only for the named fields in the template.
