LVParseTree_Iterator C API

Reference Number: AA-00963 Views: 981 0 Rating/ Voters

An LVParseTree_Iterator object traverses a parse tree in a top-to-bottom, left-to-right fashion (sometimes called a pre-order or LL traversal).  You can get an iterator over a subtree rooted at a Node by calling:

  • LVParseTree_Node_CreateIteratorBegin(H_PARSE_TREE_NODE Node)
  • LVParseTree_Node_CreateIteratorEnd(node)

Use <LVSpeechPort.h> or <LV_SRE_ParseTree.h>

Function Return Type Description
LVParseTree_Iterator_Create
(void)
H_PARSE_TREE_ITR Creates a blank Iterator; pointing at nothing.
LVParseTree_Iterator_CreateFromCopy
(H_PARSE_TREE_ITR Other)
H_PARSE_TREE_ITR Creates a new Iterator from another. Both Iterators will need to be released   when no longer needed.
LVParseTree_Iterator_Copy
(H_PARSE_TREE Iterator, H_PARSE_TREE_ITR Other)
void Copies the data from one handle into another.
LVParseTree_Iterator_Release
(H_PARSE_TREE Iterator)
void Releases the memory allocated to the Iterator handle.
LVParseTree_Iterator_Advance
(H_PARSE_TREE_ITR Iterator)
void Advances the Iterator one position.
LVParseTree_ChildrenIterator_IsPastEnd
(H_PARSE_TREE_CHILDREN_ITR Itr)
int Tests whether the iterator is past the end of the parse tree.
LVParseTree_Iterator_GetNode
(H_PARSE_TREE_ITR Iterator)
H_PARSE_TREE_NODE Provides access to a node in the parse tree.
LVParseTree_Iterator_AreEqual
(H_PARSE_TREE_ITR Iterator1, H_PARSE_TREE_ITR Iterator2)
int Tests equality with another Iterator. Two Iterators are equal if they are pointing to the same node in a parse tree.
