LAnnAutomation::EnumTextTokenTableCallBack

#include "ltwrappr.h"

virtual L_INT LAnnAutomation::EnumTextTokenTableCallBack(nTextTokenCount, nIndex, pTextToken)

L_INT nTextTokenCount;	/* total number of tokens in the text token table */
L_INT nIndex;	/* index of the text token */
pANNTEXTTOKEN pTextToken;	/* pointer to a structure that defines the text token */

Processes each text token in the annotation text token table from the LAnnAutomation::EnumerateTextTokenTable function. This function is called zero or more times as a result of a call to LAnnAutomation::EnumerateTextTokenTable.

Parameter	Description
nTextTokenCount	Total number of tokens in the text token table.
nIndex	Index of the particular token. The index is zero-based.
pTextToken	A pointer to an ANNTEXTTOKENstructure that defines the the text token. For more information, see the documentation for the ANNTEXTTOKEN structure.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

The LAnnAutomation::EnumerateTextTokenTable function calls the LAnnAutomation::EnumTextTokenTableCallBack function for each token in the annotation text token table. For example, suppose there are four entries in the text token table. A call to LAnnAutomation::EnumerateTextTokenTable() will call your overridden call back LAnnAutomation::EnumTextTokenTableCallBack function four timesonce for each token. For each of the four calls, nTextTokenCount will be 4. Since nIndex is zero-based, nIndex will be 0 in the first call to your callback function, and 3 in the last call to your callback function.

To enable this call back function you must call LBase::EnableCallBack before calling LAnnAutomation::EnumerateTextTokenTable function.
