An extension for Google's AutoValue that implements a "toQueryMap" method for Retrofit's QueryMap.

Include auto-value-querymap in your project and add a public abstract Map<String, String> toQueryMap() method to your @AutoValue annotated class.

You can also annotate your properties using @Param to define an alternate key name in the QueryMap.

@AutoValue public abstract class Foo {
  abstract String bar();                  // Will be mapped as "bar":"<value of bar>"
  @Param("Bazoo") abstract String baz();  // Will be mapped as "Bazoo":"<value of baz>"

  // This method is what auto-value-querymap will implement.
  public abstract Map<String, String> toQueryMap();
  
  // Retrofit will convert this to "?bar=<value of bar>&Bazoo=<value of baz>"
}

Now build your project and auto-value-querymap will implement the method.

• null values will not be added to the map (Not allowed by QueryMap)
• all values will be converted to String using String.valueOf()
• the map will preserve order of decleration of the fields

Add a Gradle dependency to the apt and provided configuration.

apt 'com.oguzbabaoglu:auto-value-querymap:1.0'
provided 'com.oguzbabaoglu:auto-value-querymap:1.0'

(Using the android-apt plugin)

Add a Gradle dependency to the apt and compileOnly configuration.

apt 'com.oguzbabaoglu:auto-value-querymap:1.0'
compileOnly 'com.oguzbabaoglu:auto-value-querymap:1.0'

(Using the gradle-apt-plugin plugin)

Based on the existing auto-value-map extension by Cynny.
