LVParseTree_TagIterator C API

An LVParseTree_TagIterator object is an adaptation of the standard LVParseTree_Iterator.  It only visits the nodes in a tree that are tags.  You can get a tag iterator from a Node by calling:

LVParseTree_Node_CreateTagIteratorBegin(H_PARSE_TREE_NODE Node)

LVParseTree_Node_CreateTagIteratorEnd(H_PARSE_TREE_NODE Node)

With these iterators, you can traverse all of the tags in the subtreee rooted by Node.

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

Return Type

Function

Description

H_PARSE_TREE_TAG_ITR

LVParseTree_TagIterator_Create(void)

Creates a blank iterator; its not pointing over anything.

H_PARSE_TREE_TAG_ITR

LVParseTree_TagIterator_CreateFromCopy (H_PARSE_TREE_TAG_ITR Other)

Creates a new iterator from another.  Both iterators will need to be released when no longer needed.

void

LVParseTree_TagIterator_Copy(H_PARSE_TREE_TAG_ITR Itr,
                                                          H_PARSE_TREE_TAG_ITR  Other)

Copies the data from one handle into another.

void

LVParseTree_TagIterator_Release(H_PARSE_TREE_TAG_ITR Itr)

Releases the memory allocated to the iterator handle.

 

 

 

void

LVParseTree_TagIterator_Advance(H_PARSE_TREE_TAG_ITR Itr)

Advances the iterator one position.

H_PARSE_TREE_NODE

LVParseTree_TagIterator_GetNode(H_PARSE_TREE_TAG_ITR Itr)

Provides access to a node in the parse tree.

int

LVParseTree_TagIterator_AreEqual(H_PARSE_TREE_TAG_ITR Itr1,
                                                                 H_PARSE_TREE_TAG_ITR Itr2)

Tests equality with another iterator. Two iterators are equal if they are pointing to the same node in a parse tree.
