LVParseTree_ChildrenIterator C API

Reference Number: AA-00962 Views: 798 0 Rating/ Voters

An LVParseTree_ChildrenIterator object traverses the immediate children of a rule node, from left to right.You get a ChildrenIterator object from a Node by calling

  • LVParseTree_Node_CreateChildrenIteratorBegin(H_PARSE_TREE_NODE Node)
  • LVParseTree_Node_CreateChildrenIteratorEnd(H_PARSE_TREE_NODE Node)

With these iterators, you can traverse the immediate children of Node.

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

Function Return Type Description
LVParseTree_ChildrenIterator_Create(void) H_PARSE_TREE_CHILDREN_ITR Creates a blank iterator; pointing at nothing.
LVParseTree_ChildrenIterator_CreateFromCopy
(H_PARSE_TREE_CHILDREN_ITR Other)
H_PARSE_TREE_CHILDREN_ITR Creates a new iterator from another.  Both iterators will need to be released   when no longer needed.
LVParseTree_ChildrenIterator_Copy
(H_PARSE_TREE_CHILDREN_ITR Itr, H_PARSE_TREE_CHILDREN_ITR  Other)
void Copies the data from one handle into another.
LVParseTree_ChildrenIterator_Release
(H_PARSE_CHILDREN_ITR Itr)
void Releases the memory allocated to the iterator handle.
LVParseTree_ChildrenIterator_Advance
(H_PARSE_TREE_CHILDREN_ITR Itr)
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_ChildrenIterator_GetNode
(H_PARSE_TREE_CHILDREN_ITR Itr)
H_PARSE_TREE_NODE Provides access to a node in the parse tree.
LVParseTree_ChildrenIterator_AreEqual
(H_PARSE_TREE_CHILDREN_ITR Itr1, H_PARSE_TREE_CHILDREN_ITR Itr2)
int Tests equality with another iterator. Two iterators are equal if they are pointing to the same node in a parse tree.
