Interface ResponseMapFactory

  • All Known Implementing Classes:
    DefaultResponseMapFactory
    @ExperimentalApi
@PublicSpi
public interface ResponseMapFactory
    Allows to customize the concrete class Map implementation. For example, it could be possible to use memory-efficient implementations, like eclipse-collections.

      Modifier and Type Method Description
      java.util.Map<java.lang.String,​java.lang.Object> createInsertionOrdered​(java.util.List<java.lang.String> keys, java.util.List<java.lang.Object> values)
      The general contract is that the resulting map keeps the insertion orders of keys.

      • createInsertionOrdered

        java.util.Map<java.lang.String,​java.lang.Object> createInsertionOrdered​(java.util.List<java.lang.String> keys,
                                                                              java.util.List<java.lang.Object> values)
        The general contract is that the resulting map keeps the insertion orders of keys. Values are nullable but keys are not. Implementations are free to create or to reuse map instances.
        Parameters:
        keys - the keys like k1, k2, ..., kn
        values - the values like v1, v2, ..., vn
        Returns:
        a new or reused map instance with (k1,v1), (k2, v2), ... (kn, vn)
