Field Detail

PredefinedJavaClasses

public static final java.util.Map<com.linkedin.data.schema.DataSchema,java.lang.Class<?>> PredefinedJavaClasses

Rest.li pre-defines some commonly used Java data template classes such as IntegerArray. This generator will directly use these classes instead of generate them anew.
