# SoEngineOutputList(3iv)

maintains a list of pointers to engine outputs

## NAME

SoEngineOutputList — maintains a list of pointers to engine outputs

## INHERITS FROM

SbPList \> SoEngineOutputList

## SYNOPSIS

**#include \<Inventor/SoLists.h\>**

Methods from class SoEngineOutputList:

	**SoEngineOutputList()**\
 	**SoEngineOutputList(int size)**\
 	**SoEngineOutputList(const SoEngineOutputList &l)**\
 	**~SoEngineOutputList()**\
 **void**	**append(SoEngineOutput \*engineOutput)**\
 **void**	**insert(SoEngineOutput \*engineOutput, int addBefore)**\
 **void**	**set(int i, SoEngineOutput \*engineOutput)**\
 **SoEngineOutput \***	**operator \[\](int i) const**

Methods from class SbPList:

**int**	**find(const void \*ptr) const**\
 **void**	**remove(int which)**\
 **int**	**getLength() const**\
 **void**	**truncate(int start)**\
 **void**	**copy(const SbPList &pl)**\
 **SbPList &**	**operator =(const SbPList &pl)**\
 **int**	**operator ==(const SbPList &pl) const**\
 **int**	**operator !=(const SbPList &pl) const**

## DESCRIPTION

**This subclass of SbPlist** holds lists of pointers to **SoEngineOutput**s. It updates reference counts to engine outputs in the list whenever adding or removing pointers.

## METHODS

	**SoEngineOutputList()**\
 Constructor.

	**SoEngineOutputList(int size)**\
 Constructor that pre-allocates storage for **size** pointers.

	**SoEngineOutputList(const SoEngineOutputList &l)**\
 Constructor that copies the contents of another list.

	**~SoEngineOutputList()**\
 Destructor.

**void**	**append(SoEngineOutput \*engineOutput)**\
 Adds an engine output to the end of the list.

**void**	**insert(SoEngineOutput \*engineOutput, int addBefore)**\
 Inserts the given engine output in the list before the element of the given index.

**void**	**set(int i, SoEngineOutput \*engineOutput)**\
 Sets an element of a list.

**SoEngineOutput \***	**operator \[\](int i) const**\
 Accesses an element of a list.
