Enum CompileOrder

java.lang.Object

java.lang.Enum<CompileOrder>

xsbti.compile.CompileOrder

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<CompileOrder>

public enum CompileOrder
extends java.lang.Enum<CompileOrder>

Define the order in which Scala and Java compilation should happen. This compilation order matters when the sources to be compiled are both Scala and Java sources, in which case the Zinc compiler needs a strategy to deal with the compilation order. Therefore, this setting has no effect if only Java or Scala sources are being compiled.

Enum Constant Detail

Mixed

public static final CompileOrder Mixed

Allow Scala sources to depend on Java sources and allow Java sources to depend on Scala sources. Under this mode, both Java and Scala sources can depend on each other. Java sources are also passed to the Scala compiler, which parses them, populates the symbol table and lifts them to Scala trees without generating class files for the Java trees. Then, the incremental compiler will add the generated Scala class files to the classpath of the Java compiler so that Java sources can depend on Scala sources. For more information on the way Mixed and ScalaThenJava mode behave, see this link.

JavaThenScala

public static final CompileOrder JavaThenScala

Allow Scala sources to depend on the Java sources, but it does not allow Java sources to depend on Scala sources. When mixed compilation is not required, it's generally more efficient JavaThenScala than ScalaThenJava because the Scala compiler will not parse Java sources, it will just unpickle the symbol information from class files.

ScalaThenJava

public static final CompileOrder ScalaThenJava

Allow Java sources to depend on Scala sources, but it does not allow Java sources to depend on Scala sources. Because of the way the Scala compiler works with regard to Java sources, Zinc has to enforce this mode by removing Java sources from the actual source arguments that are passed to the Scala compiler, otherwise it'll behave exactly as Mixed. For more information on the way Mixed and ScalaThenJava mode behave, see this link.

Method Detail

values

public static CompileOrder[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (CompileOrder c : CompileOrder.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static CompileOrder valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
