jminusminus.JVariableDeclaration

 class JVariableDeclaration
extends JStatement

The AST node for a local variable declaration. Local variables are declared by analyze(), which also re-writes any initializations as assignment statements, in turn generated by codegen().

Constructor Detail

JVariableDeclaration

public JVariableDeclaration(int line,
                    ArrayList<String> mods,
                    ArrayList<JVariableDeclarator> decls)

Construct an AST node for a variable declaration given the line number, modifiers, and the variable declarators.

Parameters:

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

mods - modifiers.

decls - variable declarators.

Method Detail

mods

public ArrayList<String> mods()

Return the list of modifiers.

Returns:

list of modifiers.

analyze

public JStatement analyze(Context context)

We declare the variable(s). Initializations are rewritten as assignment statements.

Specified by:

analyze in class JAST

Parameters:

context - context in which names are resolved.

Returns:

the analyzed (and possibly rewritten) AST subtree.

codegen

public void codegen(CLEmitter output)

Local variable initializations (rewritten as assignments in analyze()) are generated here.

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.
