Field Summary

java.util.Vector	args An ExpressionNode vector for each dimension or for each actual parameter of the class constructor.
boolean	array This flag determines if the parameters in the args vector correspond to an array allocation or a constructor call.
junc.symtab.Symbol	className Here we keep the type name to which the invoked constructor belongs.
int	dims The number of non-empty dimensions being specified.
junc.types.JUnCBaseType	etype Type of elements allocated.
junc.ast.MethodDeclarationNode	mnode A pointer to the constructor's declaration node.

Field Detail

etype

public junc.types.JUnCBaseType etype

Type of elements allocated. The final type is determined by typeCheck() and set in the corresponding base class field.

args

public java.util.Vector args

An ExpressionNode vector for each dimension or for each actual parameter of the class constructor. Empty expressions in array allocations like a[4][][] are filled with refs to the NullLiteral.

dims

public int dims

The number of non-empty dimensions being specified. This is calculated by the typeCheck() method.

array

public boolean array

This flag determines if the parameters in the args vector correspond to an array allocation or a constructor call.

mnode

public junc.ast.MethodDeclarationNode mnode

A pointer to the constructor's declaration node.

className

public junc.symtab.Symbol className

Here we keep the type name to which the invoked constructor belongs.
