Method Summary

void	addDeclaration(Declaration decl) Add a declaration to the end of the set of declarations and place the declared symbols in the symbol table.
void	addDeclarationAfter(Declaration ref, Declaration decl) Add a declaration after the reference declaration.
void	addDeclarationBefore(Declaration ref, Declaration decl) Add a declaration before the reference declaration.
static void	defaultPrint(WhileLoop loop, java.io.OutputStream stream) Prints a loop to a stream.
Declaration	findSymbol(IDExpression name) Retrieves the declaration for a symbol, possibly searching through parent symbol tables.
Statement	getBody() Returns the statement that is the body of the loop.
Expression	getCondition() Returns the expression that determines the duration of the loop.
java.util.List<SymbolTable>	getParentTables() Returns a list of symbol tables that are parents of this table in the distributed symbol table graph.
java.util.HashMap<IDExpression,Declaration>	getTable() Provides direct access to the symbol table; it's generally not a good idea to modify this directly.
void	setBody(Statement body)
static void	setClassPrintMethod(java.lang.reflect.Method m) Overrides the class print method, so that all subsequently created objects will use the supplied method.
void	setCondition(Expression cond)
java.lang.String	toString() Returns a string representation of this statement; every child class should implement this method.

Method Detail

addDeclaration

public void addDeclaration(Declaration decl)

Description copied from interface: SymbolTable

Add a declaration to the end of the set of declarations and place the declared symbols in the symbol table.

Specified by:

addDeclaration in interface SymbolTable

Parameters:

decl - The declaration to add.

addDeclarationBefore

public void addDeclarationBefore(Declaration ref,
                                 Declaration decl)

Description copied from interface: SymbolTable

Add a declaration before the reference declaration.

Specified by:

addDeclarationBefore in interface SymbolTable

Parameters:

ref - The reference point.

decl - The declaration to add.

addDeclarationAfter

public void addDeclarationAfter(Declaration ref,
                                Declaration decl)

Description copied from interface: SymbolTable

Add a declaration after the reference declaration.

Specified by:

addDeclarationAfter in interface SymbolTable

Parameters:

ref - The reference point.

decl - The declaration to add.

defaultPrint

public static void defaultPrint(WhileLoop loop,
                                java.io.OutputStream stream)

Prints a loop to a stream.

Parameters:

loop - The loop to print.

stream - The stream on which to print the loop.

toString

public java.lang.String toString()

Description copied from class: Statement

Returns a string representation of this statement; every child class should implement this method.

Specified by:

toString in class Statement

findSymbol

public Declaration findSymbol(IDExpression name)

Description copied from interface: SymbolTable

Retrieves the declaration for a symbol, possibly searching through parent symbol tables.

Specified by:

findSymbol in interface SymbolTable

Parameters:

name - The name of the symbol.

getBody

public Statement getBody()

Description copied from interface: Loop

Returns the statement that is the body of the loop.

Specified by:

getBody in interface Loop

Returns:

the body of the loop.

setBody

public void setBody(Statement body)

getCondition

public Expression getCondition()

Description copied from interface: Loop

Returns the expression that determines the duration of the loop.

Specified by:

getCondition in interface Loop

Returns:

the condition that is tested each iteration.

setCondition

public void setCondition(Expression cond)

getParentTables

public java.util.List<SymbolTable> getParentTables()

Description copied from interface: SymbolTable

Returns a list of symbol tables that are parents of this table in the distributed symbol table graph. A list is necessary because representing multiple inheritence in C++ requires it. Note that the parent tables are not necessarily tables of the immediate parent. The list is all symbol tables enclosing this object which appear at the same level such that no other symbol tables appear between this object and those tables.

Specified by:

getParentTables in interface SymbolTable

Returns:

a List of SymbolTables.

getTable

public java.util.HashMap<IDExpression,Declaration> getTable()

Description copied from interface: SymbolTable

Provides direct access to the symbol table; it's generally not a good idea to modify this directly.

Specified by:

getTable in interface SymbolTable

Returns:

a map of IDExpressions to Declarations.

setClassPrintMethod

public static void setClassPrintMethod(java.lang.reflect.Method m)

Overrides the class print method, so that all subsequently created objects will use the supplied method.

Parameters:

m - The new print method.
