public Interface ICompiler

Special value for setClassFileCreator(ResourceCreator): Indicates that .class resources are to be created in the directory of the .java resource from which they are generated.

Special value for setClassFileFinder(ResourceFinder).

See Also

setClassFileFinder(ResourceFinder)

Special value for setDestinationDirectory(File, boolean)'s first parameter: Indicates that .class files are to be created in the directory of the .java file from which they are generated.

Reads a set of Java compilation units (a.k.a. "source files") from the file system, compiles them into a set of "class files" and stores these in the file system. Additional source files are parsed and compiled on demand through the "source path" set of directories.

For example, if the source path comprises the directories "A/B" and "../C", then the source file for class "com.acme.Main" is searched in

A/B/com/acme/Main.java

../C/com/acme/Main.java

Notice that it does make a difference whether you pass multiple source files to compile(File[]) or if you invoke compile(File[]) multiply: In the former case, the source files may contain arbitrary references among each other (even circular ones). In the latter case, only the source files on the source path may contain circular references, not the sourceFiles.

This method must be called exactly once after object construction.

Compile errors are reported as described at setCompileErrorHandler(ErrorHandler).

Parameters

sourceFiles:File[]

Contain the compilation units to compile

Returns:boolean

true for backwards compatibility (return value can safely be ignored)

Exceptions

CompileException:

Fatal compilation error, or the CompileException thrown be the installed compile error handler

IOException:

Occurred when reading from the sourceFiles

See compile(File[]).

Parameters

sourceResources:Resource[]

Contain the compilation units to compile

Equivalent of --boot-class-path.

Annotations

@Deprecated

This ResourceCreator is used to store generated .class files.

The default is, as for JAVAC, CREATE_NEXT_TO_SOURCE_FILE.

Parameters

classFileCreator:ResourceCreator

Special value CREATE_NEXT_TO_SOURCE_FILE means "create .class file next to its source file, not in the destination directory"

See Also

CREATE_NEXT_TO_SOURCE_FILE

Equivalent with setClassFileFinder(rebuild ? ResourceFinder.EMPTY_RESOURCE_FINDER : classFileFinder).

This ResourceFinder is used to check whether a .class resource already exists and is younger than the .java resource from which it was generated.

If it is impossible to check whether an already-compiled class file exists, or if you want to enforce recompilation, pass ResourceFinder#EMPTY_RESOURCE_FINDER as the classFileFinder.

The default is, as for JAVAC, FIND_NEXT_TO_SOURCE_FILE.

Parameters

classFileFinder:ResourceFinder

Special value FIND_NEXT_TO_SOURCE_FILE means ".class file is next to its source file, not in the destination directory"

See Also

FIND_NEXT_TO_SOURCE_FILE

Equivalent of --class-path.

Installs an ErrorHandler which is invoked during compilation on each error. (By default, the compilation throws a CompileException on the first error and terminates.)

If the given ErrorHandler throws a CompileException, then the compilation terminates and the exception is propagated.

If the given ErrorHandler does not throw a CompileException but completes normally, then the compilation may or may not continue, depending on the error. Iff the compilation of a compilation unit completes normally but errors were reported, then it will throw a CompileException indicating the number of errors.

In other words: The ErrorHandler may throw a CompileException or not, but the compilation will definitely throw a CompileException if one or more compile errors have occurred.

Parameters

errorHandler:ErrorHandler

null to restore the default behavior (throwing a CompileException)

Equivalent of -g:lines.

Equivalent of -g:source.

Equivalent of -g:vars.

Equivalent of -d and -rebuild.

Overrides any previously configured class file finder and class file creator.

Parameters

destinationDirectory:File

NO_DESTINATION_DIRECTORY means "create .class resources in the directory of the .java resource from which they are generated"

See Also

NO_DESTINATION_DIRECTORY, setClassFileFinder(ResourceFinder), setClassFileCreator(ResourceCreator)

The equivalent of JAVA's "-encoding" command line option.

See Also

setSourceCharset(Charset)

Equivalent of -extdirs.

Same as setEncoding(Charset), but with a more precise name.

Finds more .java resources that need to be compiled, i.e. implements JAVAC's -sourcepath option.

Equivalent of --source-path.

Equivalent with setSourceFinder(new PathResourceFinder(directoriesAndArchives)).

Specifies the version of source code accepted, in analogy with JAVAC's -source command line option. May be ignored by an implementation (e.g. the janino implementation always accepts the language features as described on the home page). Allowed values, and the default value, depend on the implementation. -1 means to use a default version.

Generates class files that target a specified release of the virtual machine, in analogy with JAVAC's -target command line option. Allowed values depend on the implementation. The default value also depends on the implementation. The only invariant is that the generated class files are suitable for the currently executing JVM. -1 means to use a default version.

Equivalent of -verbose.

By default, warnings are discarded, but an application my install a custom WarningHandler.

Parameters

warningHandler:WarningHandler

null to indicate that no warnings be issued
