Class BindingsTemplate

  • public class BindingsTemplate
extends java.lang.Object
    Maps a set of parameters on an associated object of type T to specifiers for data mappers. Allows for easy construction of DataMapperBindings when in the proper thread scope.

    The user is required to call @{link resolveBindings} when in the scope that the resulting bindings will be used in.

        public void addFieldBinding​(java.lang.String bindPointName,
                            java.lang.String genSpec)
        Add a named binding specifier to the template
        Parameters:
        bindPointName - the name associated with the binding specifier
        genSpec - the binding specifier

      • addFieldBindings

        public void addFieldBindings​(java.util.Map<java.lang.String,​java.lang.String> bindPairs)
        Add multiple named bindings to the template
        Parameters:
        bindPairs - A map of named binding specifiers

      • resolveBindings

        public Bindings resolveBindings()
        Use the data mapping library and the specifier to create instances of data mapping functions. If you need thread-aware mapping, be sure to call this in the proper thread. Each time this method is called, it creates a new instance.
        Returns:
        A set of bindings that can be used to yield mapped data values later.
