public void addASTChild(de.hunsicker.antlr.ASTPair currentAST, de.hunsicker.antlr.collections.AST child)
currentAST
- root pair.child
- new child to add.public de.hunsicker.antlr.collections.AST create()
public de.hunsicker.antlr.collections.AST create(int type)
type
- information to setup the node with.
public de.hunsicker.antlr.collections.AST create(de.hunsicker.antlr.collections.AST node)
node
- node to setup the new node with.
public de.hunsicker.antlr.collections.AST create(de.hunsicker.antlr.Token token)
token
- token to setup the new node with.
public de.hunsicker.antlr.collections.AST create(int type, java.lang.String text)
type
- type information to setup the node with.text
- text to setup the node with.
public de.hunsicker.antlr.collections.AST dupList(de.hunsicker.antlr.collections.AST t)
t
- the root node of the tree (or tree portion)
public de.hunsicker.antlr.collections.AST dupTree(de.hunsicker.antlr.collections.AST t)
t
- the root node of the tree (or tree portion)
public void error(java.lang.String message)
message
- an error message.public de.hunsicker.antlr.collections.AST make(de.hunsicker.antlr.collections.AST[] nodes)
null
, then the tree is actually a simple list not a
tree. Handles null
children nodes correctly. For example,
build(a, b, null, c)
yields tree (a b c)
.
build(null,a,b)
yields tree (nil a b)
.
Sets also the line/column info of the root node.
nodes
- the nodes to create the tree with.
public void makeASTRoot(de.hunsicker.antlr.ASTPair currentAST, de.hunsicker.antlr.collections.AST root)
