_LT()

pANTLR3_BASE_TREE _LT ( pANTLR3_TREE_NODE_STREAM tns, ANTLR3_INT32 k )

static

Get tree node at current input pointer + i ahead where i=1 is next node.

i<0 indicates nodes in the past. So -1 is previous node and -2 is two nodes ago. LT(0) is undefined. For i>=n, return null. Return null for LT(0) and any index that results in an absolute address that is negative.

This is analogous to the _LT() method of the TokenStream, but this returns a tree node instead of a token. Makes code gen identical for both parser and tree grammars. :)

addNavigationNode()

void addNavigationNode ( pANTLR3_COMMON_TREE_NODE_STREAM ctns, ANTLR3_UINT32 ttype )

static

As we flatten the tree, we use UP, DOWN nodes to represent the tree structure.

When debugging we need unique nodes so instantiate new ones when uniqueNavigationNodes is true.

Replace from start to stop child index of parent with t, which might be a list.

Number of children may be different after this call. The stream is notified because it is walking the tree and might need to know you are monkey-ing with the underlying tree. Also, it might be able to modify the node stream to avoid re-streaming for future phases.

If parent is null, don't do anything; must be at root of overall tree. Can't replace whatever points to the parent externally. Do nothing.

size()

ANTLR3_UINT32 size ( pANTLR3_INT_STREAM is )

static

Expensive to compute the size of the whole tree while parsing.

This method only returns how much input has been seen so far. So after parsing it returns true size.

toString()

pANTLR3_STRING toString ( pANTLR3_TREE_NODE_STREAM tns )

Print out the entire tree including DOWN/UP nodes.

Uses a recursive walk. Mostly useful for testing as it yields the token types not text.
