Constructor Detail

JSuper

public JSuper(int line)

Construct an AST node for a "super" expression given its line number.

Parameters:

line - line in which the expression occurs in the source file.

Method Detail

analyze

public JExpression analyze(Context context)

Analysis involves determining the super class to that in which we are in; this becomes the type.

Specified by:

analyze in class JExpression

Parameters:

context - context in which names are resolved.

Returns:

the analyzed (and possibly rewritten) AST subtree.

codegen

public void codegen(CLEmitter output)

Load "this" onto the stack (even if we treat it as its super class.

Specified by:

codegen in class JAST

Parameters:

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

writeToStdOut

public void writeToStdOut(PrettyPrinter p)

Description copied from class: JAST

Write the information pertaining to this AST to STDOUT.

Specified by:

writeToStdOut in class JAST

Parameters:

p - for pretty printing with indentation.
