Detailed Description
Multiple-value field containing any number of nodes.
This field maintains a set of SoNode instances , correctly maintaining their reference counts.
SoMFNodes are written to file as one or more nodes. When more than one value is present, all of the values are enclosed in square brackets and separated by commas; for example:
[ Cube {} , Sphere { radius 2.0 }, USE myTranslation ]
Data copying:
- SoMF fields are a kind of "smart container", automatically expanding as necessary to hold the data provided by the application. This is very convenient, but for large blocks of data it may be desireable to avoid making a copy of the application data. The setValuesPointer() methods allow Open Inventor to directly use an array of values supplied by the application. The application data is not copied. Please see SoMFVec3f for more information and example code.
Constructor & Destructor Documentation
| SoMFNode::SoMFNode | ( | ) |
Default constructor.
| virtual SoMFNode::~SoMFNode | ( | ) | [virtual] |
Destructor.
Member Function Documentation
| void SoMFNode::addNode | ( | SoNode * | node | ) |
Adds a node as last one in group.
| virtual void SoMFNode::disableDeleteValues | ( | ) | [inline, virtual] |
Temporary disable value deleting.
| virtual void SoMFNode::enableDeleteValues | ( | ) | [inline, virtual] |
Sets the enableDeleteValues flag.
This flag (if TRUE) allows Open Inventor to destroy the user data array given to setValuesPointer(). This user data array will be managed exactly like internal field data values. Default is FALSE.
Finds the given targetValue in the array and returns the index of that value.
in the array. If the value is not found, -1 is returned. If addIfNotFound is set, then targetValue is added to the end of the array (but -1 is still returned).
| int SoMFNode::findNode | ( | const SoNode * | node | ) | const |
Finds index of given node within group.
| void SoMFNode::finishEditing | ( | ) |
Indicates that batch edits have finished.
- See also:
- startEditing().
| static SoType SoMFNode::getClassTypeId | ( | ) | [static] |
Returns the type identifier for this class.
Reimplemented from SoMField.
| SoNode* SoMFNode::getNode | ( | int | index | ) | const |
Returns pointer to nth node node.
| int SoMFNode::getNumNodes | ( | ) | const |
Returns number of nodes.
| virtual SoType SoMFNode::getTypeId | ( | ) | const [virtual] |
Returns the type identifier for this specific instance.
Implements SoTypedObject.
| const SoNode* * SoMFNode::getValues | ( | int | start | ) | const [inline] |
Returns a pointer into the array of values in the field, starting at index start.
The values are read-only. See the startEditing()/finishEditing() methods for a way of modifying values in place.
| virtual size_t SoMFNode::getValueSize | ( | ) | const [inline, virtual] |
Get size of the value.
Reimplemented from SoField.
| void SoMFNode::insertNode | ( | SoNode * | node, | |
| int | newNodeIndex | |||
| ) |
Adds a node so that it becomes the one with the given index.
| virtual SbBool SoMFNode::isDeleteValuesEnabled | ( | ) | [inline, virtual] |
Returns FALSE if user data array has been given to.
setValuesPointer() and enableDeleteValues() has never been called, and memory for data has not been reallocated. Otherwise, returns TRUE.
| int SoMFNode::operator!= | ( | const SoMFNode & | f | ) | const [inline] |
Returns TRUE if all of the values of this field do not equal.
those of the given f. If the fields are different types TRUE will always be returned.
Reimplemented from SoField.
Sets the first value in the array to newValue, and deletes.
the second and subsequent values.
| int SoMFNode::operator== | ( | const SoMFNode & | f | ) | const |
Returns TRUE if all of the values of this field equal those of.
the given f. If the fields are different types FALSE will always be returned.
Reimplemented from SoField.
| SoNode* SoMFNode::operator[] | ( | int | i | ) | const [inline] |
Returns the i'th value of the field.
Indexing past the end of the field (passing in i greater than getNum()) will return garbage.
| void SoMFNode::removeAllNodes | ( | ) |
Removes all nodes from group.
| void SoMFNode::removeNode | ( | SoNode * | node | ) | [inline] |
Removes first instance of given node from group.
| void SoMFNode::removeNode | ( | int | index | ) |
Removes node with given index from group.
Replaces first instance of given node with new node.
| void SoMFNode::replaceNode | ( | int | index, | |
| SoNode * | newNode | |||
| ) |
Replaces node with given index with new node.
| void SoMFNode::set1Value | ( | int | index, | |
| SoNode * | newValue | |||
| ) |
Sets the index'th value in the array to newValue.
The array will be automatically expanded, if necessary.
| void SoMFNode::setValue | ( | SoNode * | newValue | ) |
Sets the first value in the array to newValue, and deletes.
the second and subsequent values.
| void SoMFNode::setValues | ( | int | start, | |
| int | num, | |||
| const SoNode ** | newValues | |||
| ) |
Sets num values starting at index start to the values.
in newValues. The array will automatically be made larger to accommodate the new values, if necessary.
| void SoMFNode::setValuesPointer | ( | int | num, | |
| SoNode ** | userData | |||
| ) |
| void SoMFNode::setValuesPointer | ( | int | num, | |
| const SoNode ** | userData | |||
| ) |
Sets the field to contain the num values stored in userData array.
This array will not be copied into the field: it will be directly used by the field. If num and userData are not correctly specified, the results are undefined (and probably undesirable). param num is the number of values that userData contains and must be a positive integer. param userData is an array allocated by malloc or realloc and can be deallocated by free (no constructor or destructor is called). userData must not be NULL. Its size must be at least num*sizeof(valueType).
| SoNode** SoMFNode::startEditing | ( | ) |
Returns a pointer to the internally maintained array that can be modified.
The values in the array may be changed, but values cannot be added or removed. It is illegal to call any other editing methods between startEditing() and finishEditing() (e.g. set1Value(), setValue(), etc.).
Fields, engines or sensors connected to this field and sensors are not notified that this field has changed until finishEditing() is called. Calling finishEditing() always sets the isDefault() flag to FALSE and informs engines and sensors that the field changed, even if none of the values actually were changed.
