Class Javac

java.lang.Object
  gate.util.Javac

All Implemented Interfaces:

GateConstants

Direct Known Subclasses:

Eclipse, Sun

public abstract class Javac
extends Object
implements GateConstants

This class compiles a set of java sources using the user's preferred Java compiler. The default compiler used is the Eclipse JDT compiler, but this can be overridden by the user via an option in gate.xml.

Field Summary

private static GateClassLoader	classLoader The GATE class loader.
private static Javac	compiler The compiler to use.
static String	DEFAULT_COMPILER The default compiler to use.

Method Detail

loadClasses

public static void loadClasses(Map sources)
                        throws GateException

Compiles a set of java sources and loads the compiled classes in the gate class loader.

Parameters:

sources - a map from fully qualified classname to java source

Throws:

GateException - in case of a compilation error or warning. In the case of warnings the compiled classes are loaded before the error is raised.

setCompilerTypeFromUserConfig

private static void setCompilerTypeFromUserConfig()
                                           throws GateException

Sets the type of compiler to be used, based on the user's configuration. The default is to use the Eclipse compiler unless the user requests otherwise.

Throws:

GateException

createCompilerInstance

private static Javac createCompilerInstance(String compilerType)
                                     throws GateException

Throws:

GateException

compile

public abstract void compile(Map sources)
                      throws GateException

Compile a set of Java sources, and load the resulting classes into the GATE class loader.

Parameters:

sources - a map from fully qualified classname to java source

Throws:

GateException - in case of a compilation error or warning. In the case of warnings, the compiled classes are loaded before the exception is thrown.
