## Class MultiMap

- java.lang.Object
- - io.vertx.rxjava.core.MultiMap

-     public class MultiMap
      extends Object

  This class represents a MultiMap of String keys to a List of String values.

  It's useful in Vert.x to represent things in Vert.x like HTTP headers and HTTP parameters which allow multiple values for keys.

  NOTE: This class has been automatically generated from the `original` non RX-ified interface using Vert.x codegen.

          public String get(String name)

      Returns the value of with the specified name. If there are more than one values for the specified name, the first value is returned.
      Parameters:
        `name` - The name of the header to search

        true if at least one entry is found

    - #### isEmpty

          public boolean isEmpty()

      Return true if empty
      Returns:

    - #### names
