Interface JavaFileWriter
-
- All Known Implementing Classes:
IOJavaFileWriter
public interface JavaFileWriter
This interface can be used to describe a java source file. The resulting source definition can be viewed by callingObject.toString()
or saved to a file by callingsave()
. The semantics of this interface are as follows: - Resource allocation is deferred to save - there is no need to worry about resource cleanup if an IOException is thrown from other methods (addImport, setPackage, addClass). - Any implementation of this interface must handle the closing of resources during save if an exception is thrown.Use this interface in conjunction with one or more
JavaClassWriter
instances to describe the class(es) in a java file.- Author:

Method Detail
-
setPackage
void setPackage(String packageName, String[] comments) throws IOException
Sets the package for this file. Note that the package name format must be package style (that is - it can contain . but not / or $).- Parameters:
packageName
- The name of the package for this source file.comments
- The comments shown just above the package statement. The comments are passed as an array so the line separators can be added by the implementation. Note that not all implementations will choose to make use of this comment.- Throws:
IOException
- If the package cannot be set.
-
addImport
void addImport(String importName, String[] comments) throws IOException
Adds an import statement for this source file.- Parameters:
importName
- Name of the class or package (including the *) to be imported. This string should not contain "import" or the ;comments
- The comments shown just above the import statement. The comments are passed as an array so the line separators can be added by the implementation. Note that not all implementations will choose to make use of this comment.- Throws:
IOException
- If the import information cannot be added.
-
addClass
void addClass(JavaClassWriter classWriter) throws IOException
Adds a class to this source file.- Parameters:
classWriter
- The definition of the class.- Throws:
IOException
- If the class information cannot be added.
-
save
void save() throws IOException
Saves the file by writing out the source contents to whatever file (or alternate representation) was specified (usually by the constructor of the implementation class.- Throws:
IOException
- If the file cannot be saved.
