Creating, Copying and Releasing a LVParseTree Handle

LVParseTree objects are fully copyable and assignable.

Functions

H_PARSE_TREE LVParseTree_Create()

H_PARSE_TREE LVParseTree_CreateFromCopy(H_PARSE_TREE Other)

void LVParseTree_Copy (H_PARSE_TREE Tree, H_PARSE_TREE Other)

void LVParseTree_Release (H_PARSE_TREE Tree)

Parameters

Tree

A handle to a parse tree being released or copied into

Other

A handle to a parse tree being copied.

Remarks

CreateFromCopy and Copy both perform deep copies on the handles in question.  Both handles will have to be released after either function call to release all allocated memory.  Tree handles given to the user via LV_SRE_CreateParseTree must also be released.

Example

HPORT Port;

//open the port and do a decode
//...
//when the decode is finished,grab a parse tree handle

H_PARSE_TREE Tree = LV_SRE_CreateParseTree(Port, voicechannel, index);

//start using the tree.
//...
//When you are done with it, release it.
LVParseTree_Release(Tree);
