Constructor Detail

ASTNode

public ASTNode()

ASTNode

public ASTNode(org.antlr.runtime.Token t)

Constructor.

Parameters:

t - Token for the CommonTree Node

ASTNode

public ASTNode(ASTNode node)

Method Detail

dupNode

public org.antlr.runtime.tree.Tree dupNode()

Specified by:

dupNode in interface org.antlr.runtime.tree.Tree

Overrides:

dupNode in class org.antlr.runtime.tree.CommonTree

getChildren

public ArrayList<Node> getChildren()

Description copied from interface: Node

Gets the vector of children nodes. This is used in the graph walker algorithms.

Specified by:

getChildren in interface Node

Overrides:

getChildren in class org.antlr.runtime.tree.BaseTree

Returns:

List

getName

public String getName()

Description copied from interface: Node

Gets the name of the node. This is used in the rule dispatchers.

Specified by:

getName in interface Node

Returns:

String

setUnknownTokenBoundaries

public void setUnknownTokenBoundaries()

For every node in this subtree, make sure it's start/stop token's are set. Walk depth first, visit bottom up. Only updates nodes with at least one token index < 0. In contrast to the method in the parent class, this method is iterative.

Overrides:

setUnknownTokenBoundaries in class org.antlr.runtime.tree.CommonTree

getOrigin

public ASTNodeOrigin getOrigin()

Returns:

information about the object from which this ASTNode originated, or null if this ASTNode was not expanded from an object reference

setOrigin

public void setOrigin(ASTNodeOrigin origin)

Tag this ASTNode with information about the object from which this node originated.

dump

public String dump()

setParent

public void setParent(org.antlr.runtime.tree.Tree t)

Specified by:

setParent in interface org.antlr.runtime.tree.Tree

Overrides:

setParent in class org.antlr.runtime.tree.CommonTree
