Method Detail

isAvailable

public boolean isAvailable()

Description copied from interface: CompilerInterface

Indicates whether this compiler is actually available. As in: Is it installed and located? This method should load the compiler class, which should hopefully prove whether the class can load. If this method returns true, the CompilerInterface.compile(java.util.List, java.util.List, java.util.List, java.io.File, java.util.List, java.lang.String, boolean) method should not fail due to class not being found.

Specified by:

isAvailable in interface CompilerInterface

compile

public List<? extends DJError> compile(List<? extends File> files,
                                       List<? extends File> classPath,
                                       List<? extends File> sourcePath,
                                       File destination,
                                       List<? extends File> bootClassPath,
                                       String sourceVersion,
                                       boolean showWarnings)

Description copied from interface: CompilerInterface

Compile the given files.

Specified by:

compile in interface CompilerInterface

Parameters:

files - Source files to compile.

classPath - Support jars or directories that should be on the classpath. If null, the default is used.

sourcePath - Location of additional sources to be compiled on-demand. If null, the default is used.

destination - Location (directory) for compiled classes. If null, the default in-place location is used.

bootClassPath - The bootclasspath (contains Java API jars or directories); should be consistent with sourceVersion If null, the default is used.

sourceVersion - The language version of the sources. Should be consistent with bootClassPath. If null, the default is used.

showWarnings - Whether compiler warnings should be shown or ignored.

Returns:

Errors that occurred. If no errors, should be zero length (not null).

version

public JavaVersion version()

Description copied from interface: CompilerInterface

The latest version of Java supported by the compiler

Specified by:

version in interface CompilerInterface

getName

public String getName()

Description copied from interface: CompilerInterface

Returns the name of this compiler, appropriate to show to the user.

Specified by:

getName in interface CompilerInterface

getDescription

public String getDescription()

Description copied from interface: CompilerInterface

Returns a one-line description of the compiler (such as the name and file location)

Specified by:

getDescription in interface CompilerInterface

toString

public String toString()

The toString() of this class is displayed in the "Compiler" drop down on the compiler tab.

Specified by:

toString in interface CompilerInterface

Overrides:

toString in class Object

Returns:

"None"

additionalBootClassPathForInteractions

public List<File> additionalBootClassPathForInteractions()

Description copied from interface: CompilerInterface

A compiler can instruct DrJava to include additional elements for the boot class path of the Interactions JVM.

Specified by:

additionalBootClassPathForInteractions in interface CompilerInterface

transformCommands

public String transformCommands(String interactionsString)

Transform the command line to be interpreted into something the Interactions JVM can use. This replaces "java MyClass a b c" with Java code to call MyClass.main(new String[]{"a","b","c"}). "import MyClass" is not handled here. transformCommands should support at least "run", "java" and "applet".

Specified by:

transformCommands in interface CompilerInterface

Parameters:

interactionsString - unprocessed command line

Returns:

command line with commands transformed

isSourceFileForThisCompiler

public boolean isSourceFileForThisCompiler(File f)

Always false

Specified by:

isSourceFileForThisCompiler in interface CompilerInterface

Parameters:

f - file to check if it is a source file

Returns:

true if the specified file is a source file for this compiler.

getSourceFileExtensions

public Set<String> getSourceFileExtensions()

Return the set of source file extensions that this compiler supports.

Specified by:

getSourceFileExtensions in interface CompilerInterface

Returns:

the set of source file extensions that this compiler supports.

getSuggestedFileExtension

public String getSuggestedFileExtension()

Return the suggested file extension that will be appended to a file without extension.

Specified by:

getSuggestedFileExtension in interface CompilerInterface

Returns:

the suggested file extension

getFileFilter

public FileFilter getFileFilter()

Return a file filter that can be used to open files this compiler supports.

Specified by:

getFileFilter in interface CompilerInterface

Returns:

file filter for appropriate source files for this compiler

getOpenAllFilesInFolderExtension

public String getOpenAllFilesInFolderExtension()

Return the extension of the files that should be opened with the "Open Folder..." command.

Specified by:

getOpenAllFilesInFolderExtension in interface CompilerInterface

Returns:

file extension for the "Open Folder..." command for this compiler.

supportsLanguageLevels

public boolean supportsLanguageLevels()

Return true if this compiler can be used in conjunction with the language level facility.

Specified by:

supportsLanguageLevels in interface CompilerInterface

Returns:

true if language levels can be used.

getKeywordsForFile

public Set<String> getKeywordsForFile(File f)

Return the set of keywords that should be highlighted in the specified file.

Specified by:

getKeywordsForFile in interface CompilerInterface

Parameters:

f - file for which to return the keywords

Returns:

the set of keywords that should be highlighted in the specified file.
