DESCRIPTION¶

This is the abstract base class from which all scene graph node classes are derived.

METHODS¶

void setOverride(SbBool state)

Turns override flag on or off.

SbBool isOverride() const

Returns the state of the override flag.

SoNode * copy(SbBool copyConnections = FALSE) const

Creates and returns an exact copy of the node. If the node is a group, it copies the children as well. If copyConnections is TRUE (it is FALSE by default), any connections to (but not from) fields of the node are copied, as well. Note that multiple references to a node under the node to be copied will result in multiple references to the copy of that node.

virtual SbBool affectsState() const

Returns TRUE if a node has an effect on the state during traversal. The default method returns TRUE. Node classes (such as SoSeparator) that isolate their effects from the rest of the graph override this method to return FALSE.

static SoNode * getByName(const SbName &name)

static int getByName(const SbName &name, SoNodeList &list)

A node's name can be set using SoBase::setName(). These methods allow nodes to be looked up by name. The first one returns the last node given the specified name. The second one returns the number of nodes with the given name, and adds to list pointers to those nodes.

static SoType getClassTypeId()

Returns type identifier for the SoNode class.

ACTION BEHAVIOR¶

SoSearchAction

If the node pointer, type, or name matches the search criteria, returns a path to the node.

SoWriteAction

Writes the contents of the node to the current SoOutput.

FILE FORMAT/DEFAULTS¶

This is an abstract class. See the reference page of a derived class for the format and default values.
