Constructor Detail

JThis

public JThis(int line)

Construct an AST node for a "this" 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 simply determining the type in which we are, since that determines the type of this target.

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)

Simply generate code to load "this" onto the stack.

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)

inheritDoc

Specified by:

writeToStdOut in class JAST

Parameters:

p - for pretty printing with indentation.
