Method Detail

jjtOpen

public void jjtOpen()

Description copied from interface: Node

This method is called after the node has been made the current node. It indicates that child nodes can now be added to it.

Specified by:

jjtOpen in interface Node

jjtClose

public void jjtClose()

Description copied from interface: Node

This method is called after all the child nodes have been added.

Specified by:

jjtClose in interface Node

jjtSetParent

public void jjtSetParent(Node n)

Description copied from interface: Node

This pair of methods are used to inform the node of its parent.

Specified by:

jjtSetParent in interface Node

jjtGetParent

public Node jjtGetParent()

Specified by:

jjtGetParent in interface Node

jjtAddChild

public void jjtAddChild(Node n,
                        int i)

Description copied from interface: Node

This method tells the node to add its argument to the node's list of children.

Specified by:

jjtAddChild in interface Node

jjtGetChild

public Node jjtGetChild(int i)

Description copied from interface: Node

This method returns a child node. The children are numbered from zero, left to right.

Specified by:

jjtGetChild in interface Node

jjtGetNumChildren

public int jjtGetNumChildren()

Description copied from interface: Node

Return the number of children the node has.

Specified by:

jjtGetNumChildren in interface Node

jjtAccept

public java.lang.Object jjtAccept(VhdlParserVisitor visitor,
                                  java.lang.Object data)

Accept the visitor.

Specified by:

jjtAccept in interface Node

childrenAccept

public java.lang.Object childrenAccept(VhdlParserVisitor visitor,
                                       java.lang.Object data)

Accept the visitor.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

toString

public java.lang.String toString(java.lang.String prefix)

dump

public void dump(java.lang.String prefix)

newBlock

public void newBlock()

Start a new block with a new symbol table. The current table is saved in the variable upper_symtab.

newBlock

public void newBlock(java.lang.String type,
                     java.lang.String id)

Start a new block wit a new symbol table. The current table is saved in the variable upper_symtab. Furthermore, a first symbol of type type and id id is added.
