方法详细资料

jjtOpen

public void jjtOpen()

从接口复制的说明: 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.

指定者:

jjtOpen 在接口中 Node

jjtClose

public void jjtClose()

从接口复制的说明: Node

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

指定者:

jjtClose 在接口中 Node

jjtSetParent

public void jjtSetParent(Node n)

从接口复制的说明: Node

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

指定者:

jjtSetParent 在接口中 Node

jjtGetParent

public Node jjtGetParent()

指定者:

jjtGetParent 在接口中 Node

jjtAddChild

public void jjtAddChild(Node n,
                        int i)

从接口复制的说明: Node

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

指定者:

jjtAddChild 在接口中 Node

jjtGetChild

public Node jjtGetChild(int i)

从接口复制的说明: Node

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

指定者:

jjtGetChild 在接口中 Node

jjtGetNumChildren

public int jjtGetNumChildren()

从接口复制的说明: Node

Return the number of children the node has.

指定者:

jjtGetNumChildren 在接口中 Node

jjtAccept

                        Object data)

Accept the visitor.

指定者:

jjtAccept 在接口中 Node

childrenAccept

public Object childrenAccept(ParserVisitor visitor,
                             Object data)

Accept the visitor.

toString
