Message are represented using the standard corresponding signed types in theĭSL, for compatibility with Java and older versions of Kotlin. As the message type is still defined in Java, unsigned types in the GetFoo() will return the default value for the field’s type.įor other simple field types, the corresponding Java type is chosen according toįor message and enum types, the value type is replaced with the message or enumĬlass.

fun clearFoo(): Clears the value of the field.

Set, returns the default value for the field’s type.

var foo: Int: Returns the current value of the field.

The compiler will generate the following property in the DSL: For instance, the clearer for a field named in is clearIn_(). Kotlin or methods already defined in the protobuf library, an extra underscore In a few special cases in which a field name conflicts with reserved words in Thus, the field foo_bar_baz becomes fooBarBaz.

If the name will have a prefix attached (for example, “clear”), the first.

For each underscore in the name, the underscore is removed, and the.

proto file uses lower-case with underscores

Note that properties always use camel-case naming, even if the field name in the Properties on the message object from the getters generated by Java.) In addition to the methods described in the previous section, the protocolīuffer compiler generates mutable properties in the DSL for each field defined Object FooKt inline fun foo ( block : FooKt. java file containing a Java class which represents the. proto file input, the compiler creates a wrapper Where you want the compiler to write your Java output, and the same for the The parameter to the -java_out= option is the directory

As a result, it must be invoked with two command-line flags, -java_out=Īnd -kotlin_out=. The protocol buffer compiler produces Kotlin code that builds on top of JavaĬode.
