Constructor and Description
JMethodDeclaration(int line, ArrayList<String> mods, String name, Type returnType, ArrayList<JFormalParameter> params, JBlock body) Construct an AST node for a method declaration given the line number, method name, return type, formal parameters, and the method body.

Method Summary

Methods

Modifier and Type	Method and Description
JAST	analyze(Context context) Analysis for a method declaration involves (1) creating a new method context (that records the return type; this is used in the analysis of the method body), (2) bumping up the offset (for instance methods), (3) declaring the formal parameters in the method context, and (4) analyzing the method's body.
void	codegen(CLEmitter output) Generate code for the method declaration.
void	partialCodegen(Context context, CLEmitter partial) Add this method declaration to the partial class.
void	preAnalyze(Context context, CLEmitter partial) Declare this method in the parent (class) context.
void	writeToStdOut(PrettyPrinter p) Write the information pertaining to this AST to STDOUT.

Constructor Detail

JMethodDeclaration

public JMethodDeclaration(int line,
                  ArrayList<String> mods,
                  String name,
                  Type returnType,
                  ArrayList<JFormalParameter> params,
                  JBlock body)

Construct an AST node for a method declaration given the line number, method name, return type, formal parameters, and the method body.

Parameters:

line - line in which the method declaration occurs in the source file.

mods - modifiers.

name - method name.

returnType - return type.

params - the formal parameters.

body - method body.

Method Detail

preAnalyze

public void preAnalyze(Context context,
              CLEmitter partial)

Declare this method in the parent (class) context.

Specified by:

preAnalyze in interface JMember

Parameters:

context - the parent (class) context.

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

analyze

public JAST analyze(Context context)

Analysis for a method declaration involves (1) creating a new method context (that records the return type; this is used in the analysis of the method body), (2) bumping up the offset (for instance methods), (3) declaring the formal parameters in the method context, and (4) analyzing the method's body.

Specified by:

analyze in class JAST

Parameters:

context - context in which names are resolved.

Returns:

the analyzed (and possibly rewritten) AST subtree.

partialCodegen

public void partialCodegen(Context context,
                  CLEmitter partial)

Add this method declaration to the partial class.

Overrides:

partialCodegen in class JAST

Parameters:

context - the parent (class) context.

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

codegen

public void codegen(CLEmitter output)

Generate code for the method declaration.

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.
