Method Detail

evaluate

public EvaluationResult evaluate(EvaluationContext context)
                          throws EvaluationException

Evaluate this Node.

Parameters:

context - an EvaluationContext value contains all context information necessary for the evaluation

Returns:

an EvaluationResult value

Throws:

EvaluationException - occurs if e.g. an expression contains a reference to a non-existent struct member or if it is tried to add a string and a number

acceptInOrder

public abstract void acceptInOrder(AbstractTCLVisitor visitor)
                            throws VisitorException

accept a visitor for traversal Inorder

Parameters:

visitor -

Throws:

VisitorException

acceptPreOrder

public abstract void acceptPreOrder(AbstractTCLVisitor visitor)
                             throws VisitorException

accept a visitor for traversal in Preorder. the root node is visited before the left and the right subtrees are visited.

Parameters:

visitor -

Throws:

VisitorException

acceptPostOrder

public abstract void acceptPostOrder(AbstractTCLVisitor visitor)
                              throws VisitorException

accept a visitor for traversal in Postorder. the right and left subtrees are visited before the root node is visited.

Parameters:

visitor -

Throws:

VisitorException

getName

public final String getName()

hasNextSibling

public boolean hasNextSibling()

Check wether this node has a Sibling.

Returns:

true, if this node has a Sibling

printToStringBuffer

public void printToStringBuffer(StringBuffer buffer)

toStringTree

public String toStringTree()

create a visualization of this node and all its children.

Specified by:

toStringTree in interface antlr.collections.AST

Overrides:

toStringTree in class antlr.BaseAST

Returns:

a String representation of this Node and all its children

left

public AbstractTCLNode left()

Access the left child. This method returns null if this node has no left child

Returns:

the left Child or null.

right

public AbstractTCLNode right()

Access the right child. This method returns null if this node has no right child

Returns:

the right Child or null.

isStatic

public boolean isStatic()

isNumber

public boolean isNumber()

isString

public boolean isString()

isBoolean

public boolean isBoolean()

getType

public int getType()

Get the AST Token Type for this node.

Specified by:

getType in interface antlr.collections.AST

Overrides:

getType in class antlr.BaseAST

Returns:

the AST Token Type value

See Also:

TCLParserTokenTypes

setType

public void setType(int type)

Set AST Token Type for this node.

Specified by:

setType in interface antlr.collections.AST

Overrides:

setType in class antlr.BaseAST

Parameters:

type - must be a valid TCLTokenType.

See Also:

TCLParserTokenTypes

getNameForType

public static String getNameForType(int t)

converts an int tree token type to a name. Does this by reflecting on nsdidl.IDLTreeTokenTypes, and is dependent on how ANTLR 2.00 outputs that class. this snippet was taken from http://www.codetransform.com/

initialize

public final void initialize(int t,
              String txt)

satisfy abstract method from BaseAST. Not used.

Specified by:

initialize

public final void initialize(antlr.collections.AST t)

satisfy abstract method from BaseAST. Not used.

Specified by:

initialize in interface antlr.collections.AST

Specified by:

initialize in class antlr.BaseAST

initialize

public final void initialize(antlr.Token tok)

satisfy abstract method from BaseAST. Not used.
