| Method Summary | |
| public void | add(Declaration decl)
| | public void | add(Declaration prev, Declaration decl)
Add a Declaration at a specified position. | | final public Declaration | addDeclaration(Object name)
Create a new declaration in the current Scope. | | final public Declaration | addDeclaration(Object name, Type type)
Create a new declaration in the current Scope. | | final public void | addDeclaration(Declaration decl)
Add a Declaration to the current Scope. | | public int | countDecls()
| | public LambdaExp | currentLambda()
| | public ModuleExp | currentModule()
| | public static void | duplicateDeclarationError(Declaration oldDecl, Declaration newDecl, Compilation comp)
| | public Declaration | firstDecl()
| | public Declaration | getDefine(Object name, char severity, Compilation parser)
Add a new Declaration, with a message if there is an existing one. | | public Declaration | getNoDefine(Object name)
Lookup a declaration, create a non-defining declaration if needed. | | public Scope | getVarScope()
| | public Declaration | lookup(Object sym)
Find a Declaration by name. | | public Declaration | lookup(Object sym, Language language, int namespace)
| | public static int | nesting(ScopeExp sc)
| | public void | popScope(CodeAttr code)
Clear bytecode resources for the ScopeExp. | | public void | remove(Declaration decl)
| | public void | remove(Declaration prev, Declaration decl)
| | public void | replaceFollowing(Declaration prev, Declaration newDecl)
Replace the prev.next by newDecl.
If prev==null, replace the first decl. | | protected void | setIndexes()
Calculate offset and frameSize needed by interpreter. | | public String | toString()
| | protected Expression | walk(ExpWalker walker)
|
| counter | | static int counter(Code) | | |
| frameSize | | protected int frameSize(Code) | | Size of evalFrame to allocate in interpreter.
|
| id | | public int id(Code) | | Unique id number, to ease print-outs and debugging.
|
| outer | | public ScopeExp outer(Code) | | The statically enclosing binding contour.
|
| ScopeExp | | public ScopeExp()(Code) | | |
| addDeclaration | | final public Declaration addDeclaration(Object name)(Code) | | Create a new declaration in the current Scope.
Parameters:
name - name (interned) to give to the new Declaration. |
| addDeclaration | | final public Declaration addDeclaration(Object name, Type type)(Code) | | Create a new declaration in the current Scope.
Parameters:
name - name (interned) to give to the new Declaration.
Parameters:
type - type of the new Declaration. |
| addDeclaration | | final public void addDeclaration(Declaration decl)(Code) | | Add a Declaration to the current Scope.
|
| countDecls | | public int countDecls()(Code) | | |
| getNoDefine | | public Declaration getNoDefine(Object name)(Code) | | Lookup a declaration, create a non-defining declaration if needed.
|
| lookup | | public Declaration lookup(Object sym)(Code) | | Find a Declaration by name.
Parameters:
sym - the (interned) name of the Declaration sought the matching Declaration, if found; otherwise null |
| popScope | | public void popScope(CodeAttr code)(Code) | | Clear bytecode resources for the ScopeExp.
This potentially allows Kawa to generate code for the same (inlined,
shared) ScopeExp multiple times - though we're not making use of that yet.
|
| replaceFollowing | | public void replaceFollowing(Declaration prev, Declaration newDecl)(Code) | | Replace the prev.next by newDecl.
If prev==null, replace the first decl.
|
| setIndexes | | protected void setIndexes()(Code) | | Calculate offset and frameSize needed by interpreter.
