includeStandardSourceHeaders

public void includeStandardSourceHeaders(Writer output)
                                  throws IOException

Generates the source-code includes.

Parameters:

output - the output writer

Throws:

IOException - if an I/O exception occurs while writing

generateMethodDefinitions

public void generateMethodDefinitions(Writer output,
                             boolean forPeer)
                               throws IOException

Generate the method definitions.

Parameters:

output - the output writer

forPeer - true if the methods are being generated for a peer, false for a proxy

Throws:

IOException - if an error occurs while writing

generateFieldDefinitions

public void generateFieldDefinitions(Writer output)
                              throws IOException

Same as generateFieldDefinitions(output, false).

Parameters:

output - the output writer

Throws:

IOException - if an error occurs while writing

See Also:

generateFieldDefinitions(Writer, boolean)

generateFieldDefinitions

public void generateFieldDefinitions(Writer output,
                            boolean forPeer)
                              throws IOException

Generate the field definitions.

Parameters:

output - the output writer

forPeer - true if the fields are being generated for a peer, false for a proxy

Throws:

IOException - if an error occurs while writing

generateJaceDefinitions

public void generateJaceDefinitions(Writer output)
                             throws IOException

Same as generateJaceDefinitions(output, false).

Parameters:

output - the output writer

Throws:

IOException - if an error occurs while writing

See Also:

generateJaceDefinitions(Writer, boolean).

generateJaceDefinitions

public void generateJaceDefinitions(Writer output,
                           boolean forPeer)
                             throws IOException

Generate the jace-specific methods.

Parameters:

output - the output writer

forPeer - true if the fields are being generated for a peer, false for a proxy

Throws:

IOException - if an error occurs while writing

getInitializerValue

public String getInitializerValue()

Same as getInitializerValue(false).

Returns:

the initializer list

See Also:

defineInitializerValue(boolean)

getInitializerValue

public String getInitializerValue(boolean forPeer)

Returns the initializer list for the current class. For example, ": Object(), OutputStream()" This could probably be placed in MetaClass. It might not hurt to put the initializers in some sort of array instead of a formatted String. This method used to include interfaces in the initializer list, but now that interfaces have a default constructor that does what we want, they are no longer included.

Parameters:

forPeer - true if the methods are being generated for a peer, false for a proxy

Returns:

the initializer list

generateMethodDeclaration

public void generateMethodDeclaration(Writer output,
                             MetaClass metaClass,
                             ClassMethod method,
                             ProxyGenerator.InvokeStyle invokeStyle)
                               throws IOException

Generates the method declaration.

Parameters:

output - the output writer

metaClass - the MetaClass describing the class

method - the method

invokeStyle - the method invocation style

Throws:

IOException - if an error occurs while writing

generateFieldDeclarations

public void generateFieldDeclarations(Writer output,
                             boolean forPeer)
                               throws IOException

Generates the field declarations.

Parameters:

output - the output writer

forPeer - true if the fields are being generated for a peer, false for a proxy

Throws:

IOException - if an error occurs while writing

beginNamespace

public void beginNamespace(Writer output)
                    throws IOException

Generates the opening of a namespace.

Parameters:

output - the output writer

Throws:

IOException - if an error occurs while writing

includeStandardHeaders

public void includeStandardHeaders(Writer output,
                          boolean forPeer)
                            throws IOException

Generate includes for the Jace library headers, which should always be included.

Parameters:

output - the output writer

forPeer - true if the methods are being generated for a peer, false for a proxy

Throws:

IOException - if an error occurs while writing

includeDependentHeaders

public void includeDependentHeaders(Writer output)
                             throws IOException

Includes the headers for the super-class and all implemented interfaces. This is necessary, because we can't inherit from a class unless it is fully defined.

Parameters:

IOException - if an error occurs while writing

makeForwardDeclarations

public void makeForwardDeclarations(Writer output)
                             throws IOException

Parameters:

output - the output writer

Throws:

IOException - if an error occurs while writing

getForwardDeclarations

public Set<MetaClass> getForwardDeclarations()

Returns the classes that must be forward-declared for the class we are generating. The return value includes fields, array elements, exceptions and all other parameter types but not the superclass and the interfaces implemented by this class.

Returns:

an empty set if no classes need to be forward-declared

writeProxy

public void writeProxy(File outputHeaders,
              File outputSources)
                throws IOException

Generates the C++ proxy (header and source) for the specified class.

Parameters:

outputHeaders - the directory to write the header file to

outputSources - the directory to write the source file to

Throws:

IOException - if an error occurs while writing the proxy files

main

public static void main(String[] args)
