Constructor Detail

JNewArrayOp

public JNewArrayOp(int line,
           Type typeSpec,
           ArrayList<JExpression> dimExprs)

Construct an AST node for a "new" array operation.

Parameters:

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

typeSpec - the type of the array being created.

dimExprs - a list of dimension expressions.

Method Detail

analyze

public JExpression analyze(Context context)

Analysis of a new array operation involves resolving its type and analyzing the array bounds and checking their types.

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)

Generate code to push the bounds on the stack and then generate the appropriate array creation instruction.

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.
