                                        java.lang.String prefix,
                                        java.lang.String code)
                                 throws java.io.IOException

Split a long function body into multiple inner classes.

Overrides:

splitLongBody in class ProgramCodeGenerator

Parameters:

linesPerMethod - The number of lines that should go into each method.

prefix - The prefix to use when naming inner classes that are created.

code - The method body to be split.

Returns:

An array of two Strings, where the first element is the new definitions (if any), and the second element is the new body. If the number of lines in the code parameter is less than linesPerMethod, then the first element will be the empty string and the second element will be the value of the code parameter.

Throws:

java.io.IOException - If thrown while reading the code.

splitVariableDeclaration

public java.util.List<java.lang.String> splitVariableDeclaration(int linesPerMethod,
                                                                 java.lang.String prefix,

                                                          throws java.io.IOException

Split a long variable declaration body into multiple blocks or files.

For Java, if the code consists of linesPerMethod or fewer lines, then the the first element will be the empty string and the second element will consist of the value of the code argument. If the code consists of more than linesPerMethod then the first element will consist of one or more "import static" statements and the second and possibly successive element will consist of Java classes that should be written out by _writeVariableDeclarations(List).

Overrides:

splitVariableDeclaration in class ProgramCodeGenerator

Parameters:

linesPerMethod - The number of lines that should go into each method.

prefix - The prefix to use when naming functions that are created

code - The variable declarations to be split.

Returns:

A list of at least two elements. If the code has less than _LINES_PER_METHOD lines, then the first element is empty, the second element contains the contents of the code parameter. If the code has more lines than _LINES_PER_METHOD, then the first element contains the declarations necessary for the include files section and the second element and successive elements contain the declarations. Each declaration should be placed into a file that corresponds with the include or import listed in the first element.

Throws:

java.io.IOException - If thrown while reading the code.

_writeMakefile

protected void _writeMakefile(CompositeEntity container,
                              java.lang.String currentDirectory)
                       throws IllegalActionException

Read in a template makefile, substitute variables and write the resulting makefile.

If a .mk.in file with the name of the sanitized model name, then that file is used as a template. For example, if the model name is Foo and the file Foo.mk.in exists, then the file Foo.mk.in is used as a makefile template.

If no .mk.in file is found, then the makefile template can be found by looking up a resource name makefile.in in the package named by the generatorPackage parameter. Thus, if the generatorPackage has the value "ptolemy.codegen.c", then we look for the resource "ptolemy.codegen.c.makefile.in", which is usually found as $PTII/ptolemy/codegen/c/makefile.in.

The makefile is written to a directory named by the codeDirectory parameter, with a file name that is a sanitized version of the model name, and a ".mk" extension. Thus, for a model named "Foo", we might generate a makefile in "$HOME/codegen/Foo.mk".

Under Java under Windows, your $HOME variable is set to the value of the user.homeSystem property, which is usually something like C:\Documents and Settings\yourlogin, thus for user mrptolemy the makefile would be C:\Documents and Settings\mrptolemy\codegen\Foo.mk.

The following variables are substituted

@modelName@

The sanitized model name, created by invoking StringUtilities.sanitizeName(String) on the model name.

@PTCGIncludes@

The elements of the set of include command arguments that were added by calling ProceduralCodeGenerator.addInclude(String), where each element is separated by a space.

@PTCGLibraries@

The elements of the set of library command arguments that were added by calling ProceduralCodeGenerator.addLibrary(String), where each element is separated by a space.

Overrides:

_writeMakefile in class ProceduralCodeGenerator

Parameters:

container - The composite actor for which we generate the makefile

currentDirectory - The director in which the makefile is to be written.

Throws:

IllegalActionException - If there is a problem reading a parameter, if there is a problem creating the codeDirectory directory or if there is a problem writing the code to a file.

_writeVariableDeclarations

protected java.lang.String _writeVariableDeclarations(java.util.List<java.lang.String> variableDeclarations)
                                               throws IllegalActionException

Write the variable declaration code.

If the first element is the empty String, then the second element contains all of the variable declarations and this method does not create files and the value of the second element is returned. If the first element is not the empty string, then the second and successive elements are written to a file whos name is created by parsing the first element. The first element must consist of strings like "import static variables.foo;", the file name will be "variables/foo.java".

Overrides:

_writeVariableDeclarations in class ProgramCodeGenerator

Parameters:

variableDeclarations - A List of two or more elements. first element is not empty, then it contains the language specific declarations for the variable declarations. In Java, the first element may consist of one or more "import" statements. The second and successive elements contain the code to be written to separate files or to be returned as one String.

Returns:

If the first element is empty, then return the value of the second element. If the first element is not empty, then files are created and the empty string is returned.

Throws:

IllegalActionException - Thrown if there is a problem writing the files.
