Class JClassDeclaration

java.lang.Object

jminusminus.JAST

jminusminus.JClassDeclaration

All Implemented Interfaces:

JTypeDecl

 class JClassDeclaration
extends JAST
implements JTypeDecl

A class declaration has a list of modifiers, a name, a super class and a class block; it distinguishes between instance fields and static (class) fields for initialization, and it defines a type. It also introduces its own (class) context.

Constructor Detail

JClassDeclaration

public JClassDeclaration(int line,
                 ArrayList<String> mods,
                 String name,
                 Type superType,
                 ArrayList<JMember> classBlock)

Construct an AST node for a class declaration given the line number, list of class modifiers, name of the class, its super class type, and the class block.

Parameters:

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

mods - class modifiers.

name - class name.

superType - super class type.

classBlock - class block.

Method Detail

name

public String name()

Return the class name.

Specified by:

name in interface JTypeDecl

Returns:

the class name.

superType

public Type superType()

Return the class' super class type.

Specified by:

superType in interface JTypeDecl

Returns:

the super class type.

thisType

public Type thisType()

Return the type that this class declaration defines.

Specified by:

thisType in interface JTypeDecl

Returns:

the defined type.

instanceFieldInitializations

public ArrayList<JFieldDeclaration> instanceFieldInitializations()

The initializations for instance fields (now expressed as assignment statments).

Returns:

the field declarations having initializations.

declareThisType

public void declareThisType(Context context)

Declare this class in the parent (compilation unit) context.

Specified by:

declareThisType in interface JTypeDecl

Parameters:

context - the parent (compilation unit) context.

preAnalyze

public void preAnalyze(Context context)

Pre-analyze the members of this declaration in the parent context. Pre-analysis extends to the member headers (including method headers) but not into the bodies.

Specified by:

preAnalyze in interface JTypeDecl

Parameters:

context - the parent (compilation unit) context.

analyze

public JAST analyze(Context context)

Perform semantic analysis on the class and all of its members within the given context. Analysis includes field initializations and the method bodies.

Specified by:

analyze in class JAST

Parameters:

context - the parent (compilation unit) context. Ignored here.

Returns:

the analyzed (and possibly rewritten) AST subtree.

codegen

public void codegen(CLEmitter output)

Generate code for the class 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.
