public class SoMFNode extends SoMField
Multiple-value field containing any number of nodes. This field maintains a set ofSoNode
instances.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 setValuesBuffer() 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.

Method Detail
-
find
public int find(SoNode targetValue)
Calls find(targetValue, false).
-
findNode
public int findNode(SoNode node)
Finds index of given node within group.
-
getValueAt
public SoNode getValueAt(int i)
-
setValues
public void setValues(int start, 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. In that case, if field's values are stored in an user data array, this array is no more used.
-
find
public int find(SoNode targetValue, boolean addIfNotFound)
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).
-
getNumNodes
public int getNumNodes()
Returns number of nodes.
-
disableDeleteValues
public void disableDeleteValues()
Temporary disable value deleting.
-
removeNode
public void removeNode(int index)
Removes node with given index from group.
-
addNode
public void addNode(SoNode node)
Adds a node as last one in group.
-
insertNode
public void insertNode(SoNode node, int newNodeIndex)
Adds a node so that it becomes the one with the given index.
-
getNode
public SoNode getNode(int index)
Returns pointer to nth node node.
-
removeNode
public void removeNode(SoNode node)
Removes first instance of given node from group .
-
setValue
public void setValue(SoNode newValue)
Sets the first value in the array to newValue, and deletes. the second and subsequent values. If field's values are stored in an user data array, this array is no more used.
-
set1Value
public void set1Value(int index, SoNode newValue)
Sets the index'th value in the array to newValue. The array will be automatically expanded, if necessary. In that case, if field's values are stored in an user data array, this array is no more used.
-
replaceNode
public void replaceNode(SoNode oldNode, SoNode newNode)
Replaces first instance of given node with new node.
-
removeAllNodes
public void removeAllNodes()
Removes all nodes from group.
-
replaceNode
public void replaceNode(int index, SoNode newNode)
Replaces node with given index with new node.
