Methods

Modifier and Type	Method and Description
JExpression	analyze(Context context) Analyzing a this constructor statement involves (1) setting the type, (2) analyzing the actual arguments, (3) checking that this construction statement is properly invoked (as the first statement in another constructor), and (4) finding the appropriate Constructor
void	codegen(CLEmitter output) Code generation involves generating the code for loading the actual arguments onto the stack, and then for invoking this constructor.
void	markProperUseOfConstructor() Used in JConstructorDeclaration to mark this(...) 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

JThisConstruction

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

Construct the AST node for a this(...) 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 this(...) as being properly placed, ie, as the first statement in its body.

analyze

public JExpression analyze(Context context)

Analyzing a this constructor statement involves (1) setting the type, (2) analyzing the actual arguments, (3) checking that this construction statement is properly invoked (as the first statement in another constructor), and (4) finding the appropriate 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 the code for loading the actual arguments onto the stack, and then for invoking this 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.
