Methods

Modifier and Type	Method and Description
JExpression	analyze(Context context) Analyzing a super constructor statement involves (1) setting the type, (2) analyzing the actual arguments, and (3) checking that this construction statement is properly invoked (as the first statement in another constructor).
void	codegen(CLEmitter output) Code generation involves generating code to load the actual arguments onto the stack, and then the code for invoking the constructor.
void	markProperUseOfConstructor() Used in JConstructorDeclaration to mark super(...) as being properly placed, ie, as the first statement in its body.
void	writeToStdOut(PrettyPrinter p) Write the information pertaining to this AST to STDOUT.

Constructor Detail

JSuperConstruction

protected JSuperConstruction(int line,
                  ArrayList<JExpression> arguments)

Construct an AST node for a super(...) constructor given its line number and arguments.

Parameters:

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

arguments - the constructor's arguments.

Method Detail

markProperUseOfConstructor

public void markProperUseOfConstructor()

Used in JConstructorDeclaration to mark super(...) as being properly placed, ie, as the first statement in its body.

analyze

public JExpression analyze(Context context)

Analyzing a super constructor statement involves (1) setting the type, (2) analyzing the actual arguments, and (3) checking that this construction statement is properly invoked (as the first statement in another constructor).

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)

Code generation involves generating code to load the actual arguments onto the stack, and then the code for invoking the constructor.

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.
