Field Detail

compilationUnit

public static JCompilationUnit compilationUnit

Current compilation unit (set in JCompilationUnit()).

line

protected int line

Line in which the source for the AST was found.

Constructor Detail

JAST

protected JAST(int line)

Construct an AST node the given its line number in the source file.

Parameters:

line - line in which the source for the AST was found.

Method Detail

line

public int line()

Return the line in which the source for the AST was found.

Returns:

the line number.

analyze

public abstract JAST analyze(Context context)

Perform semantic analysis on this AST. In some instances a new returned AST reflects surgery.

Parameters:

context - the environment (scope) in which code is analyzed.

Returns:

a (rarely modified) AST.

partialCodegen

public void partialCodegen(Context context,
                  CLEmitter partial)

Generate a partial class for this type, reflecting only the member information required to do analysis.

Parameters:

context - the parent (class) context.

partial - the code emitter (basically an abstraction for producing the partial class).

codegen

public abstract void codegen(CLEmitter output)

Perform code generation for this AST.

Parameters:

output - the code emitter (basically an abstraction for producing the .class file).

writeToStdOut

public abstract void writeToStdOut(PrettyPrinter p)

Write the information pertaining to this AST to STDOUT.

Parameters:

p - for pretty printing with indentation.
