Constructor Detail

ProcedureDecl

public ProcedureDecl(java.lang.String name,
                     ProcedureType type,
                     int level,
                     RoutineDecl parentRoutine,
                     Statement body)
Create a new procedure declaration.

Parameters:
name - is the procedure name
type - is the procedure type
level - is the nesting level of this procedure
parentRoutine - is the parent (enclosing) routine or null
body - is the body of the procedure

ProcedureDecl

public ProcedureDecl(java.lang.String name,
                     ProcedureType type,
                     int level,
                     RoutineDecl parentRoutine)
Create a new procedure declaration.

Parameters:
name - is the procedure name
type - is the procedure type
level - is the nesting level of this procedure
parentRoutine - is the parent (enclosing) routine or null

ProcedureDecl

public ProcedureDecl(java.lang.String name,
                     ProcedureType type)

public ProcedureDecl(java.lang.String name,
                     ProcedureType type,
                     int level,
                     Statement body)
Create a new procedure declaration.

Parameters:
name - is the procedure name
type - is the procedure type
level - is the nesting level of this procedure
body - is the body of the procedure
Method Detail

toStringSpecial

public java.lang.String toStringSpecial()
Description copied from class: Node
This method allows sub-classes to provide class specific stuff to the string.

Overrides:
toStringSpecial in class RoutineDecl

visit

public void visit(Predicate p)
Description copied from class: Node
Process a node by calling its associated routine. See the "visitor" design pattern in Design Patterns: Elements of Reusable Object-Oriented Software by E. Gamma, et al, Addison Wesley, ISBN 0-201-63361-2.

Each class has a visit(Predicate p) method. For example, in class ABC:

   public void visit(Predicate p)
   {
     p.visitABC(this);
   }
 
and the class that implements Predicate has a method
   public void visitABC(Node n)
   {
     ABC a = (ABC) n;
     ...
   }
 
Thus, the class that implements Predicate can call
   n.visit(this);
 
where n is a Node sub-class without determining which specific sub-class n is. The visit pattern basically avoids implementing a large switch statement or defining different methods in each class for some purpose.

Overrides:
visit in class RoutineDecl

Predicate

getLevel

public final int getLevel()

getParentRoutine

public final RoutineDecl getParentRoutine()

setLevel

public final void setLevel(int lev)
Set the nested depth of this routine. This value is currently always 0.


setParentRoutine

public final void setParentRoutine(RoutineDecl parentRoutine)
Set the enclosing routine of this routine. This value is currently always null.


getChild

public Node getChild(int i)
Return the specified AST child of this node.

Overrides:
getChild in class RoutineDecl

numChildren

public int numChildren()
Return the number of AST children of this node.

Overrides:
numChildren in class RoutineDecl

Overrides:
isProcedureDecl in class Declaration
