Class DependenciesGenerator

java.lang.Object

gov.llnl.babel.backend.DependenciesGenerator

All Implemented Interfaces:

BuildGenerator, ContextAware, FileListener

public class DependenciesGenerator
extends java.lang.Object
implements FileListener, BuildGenerator, ContextAware

This class is used to generate makefiles but may be amenable to extension to other types of build files. gets the database of generated files from the FileManager. It then create makefiles

Method Detail

newFile

public void newFile(SymbolID id,
           int type,
           java.lang.String role,
           java.lang.String dir,
           java.lang.String name)

This method is called for each file created by the FileManager.

Specified by:

newFile in interface FileListener

Parameters:

id - the file is related to this symbol id.

type - this indicates the type of the symbol. A constant from Type.

role - this describes the role the file plays. For example, the file could be a STUBSRCS file or a IMPLSRCS file. The role strings used are determined by the backend.

dir - the path (relative or absolute) of the directory where the file will be created.

name - the name of the file not including any directory information. The complete name of the file should be dir + name.

createAll

public void createAll()
               throws java.io.IOException

Create all Makefiles in all the directories registered with the FileManager.

Specified by:

createAll in interface BuildGenerator

Throws:

java.io.IOException - the message contained is the concatenation of all IOExceptions thrown by createMakefileInDirectory

See Also:

FileManager

createMakefileInDirectory

public void createMakefileInDirectory(java.lang.String dependfilename,
                             java.lang.String dirname)
                               throws java.io.IOException

Create a single makefile in a specific directory. This will do nothing if there are no files defined in that directory according to the FileManager class.

Parameters:

dependfilename - set makefile name, if null or "", defaults to <make-prefix> + "babel.make"

dirname - directory to look for

Throws:

java.io.IOException - if problems are encountered with the file system.

FileManager

writeMakefile

protected void writeMakefile(java.io.PrintWriter pw,
                 java.util.Map role2files,
                 java.util.HashMap fileData)

Generate the actual make file. This method can be overridden for tools other than make provided that whatever files are generated exist in the same directory as the sourcecode.

Parameters:

fileData: - keyed by filename(leaf) and valued by prerequisite filenames in a List.

defaultFilename

protected java.lang.String defaultFilename()

Return the default file name. This method can be overridden in derived classes if a different default name is preferred.

Returns:

value of the make file name

defaultDependencyFilename

protected java.lang.String defaultDependencyFilename()

Return the default file name. This method can be overridden in derived classes if a different default name is preferred.

Returns:

value of the make file name

defaultPackageDependencyFilename

protected java.lang.String defaultPackageDependencyFilename()

getLanguages

public java.util.Set getLanguages()

Description copied from interface: BuildGenerator

Return the set of languages that this build generator serves. Each build generator serves a Set of languages.

Specified by:

getLanguages in interface BuildGenerator

Returns:

a Set of strings. Each string in the set represents a language supported by the build generator.

setContext

public void setContext(Context context)

Description copied from interface: ContextAware

Routine to notify extensions of the context.

Specified by:

setContext in interface ContextAware
