Returns TRUE if this field is being written into by another field, and returns the field it is connected to in writingField. | |
| int | getForwardConnections (SoFieldList &list) const |
| Adds pointers to all of the fields that this field is writing into (either fields in nodes, global fields or engine inputs) to the given field list, and returns the number of forward connections. | |
| SoFieldContainer * | getContainer () const |
| Returns the containing node or engine. | |
| bool | set (const char *valueString) |
| Sets the field to the given value, which is an ASCII string in the Inventor file format. | |
| void | get (SbString &valueString) |
| Returns the value of the field in the Inventor file format, even if the field has its default value. | |
| virtual void | touch () |
| Simulates a change to the field, causing attached sensors to fire, connected fields and engines to be marked as needing evaluation, and so forth. | |
| bool | operator== (const SoField &f) const |
Return TRUE (FALSE) if this field is of the same type and has the same value as f. | |
| bool | operator!= (const SoField &f) const |
Return TRUE (FALSE) if this field is of the same type and has the same value as f. | |
| void | setDefault (bool def) |
| Sets default flag. | |
| virtual void | startNotify () |
| Initiates or propagates notification through container. | |
| virtual void | notify (SoNotList *list) |
| void | setContainer (SoFieldContainer *cont) |

| virtual void | connectionStatusChanged (int numConnections) |
| Indicates to a field that a change has been made involving a connection from it (as source) to another field. | |
| bool | isReadOnly () const |
| If this returns TRUE, it means we're in the middle of doing a setValue()+valueChanged() and values from an upstream connection shouldn't write into this field. | |
| virtual bool | isSame (const SoField &f) const =0 |
| Returns TRUE if the given field is of the same type and has the same value(s) as this. | |
| virtual void | copyFrom (const SoField &f)=0 |

| virtual void | fixCopy (bool copyConnections) |
| After a field value has been copied using copyFrom(), this is called to allow fields to update the copy. | |
| virtual bool | referencesCopy () const |
| This returns TRUE if this field contains a reference to a node or engine that is copied during a copy operation (i.e., it is "inside"). | |
| void | copyConnection (const SoField *fromField) |
| Copies connection from one field to another. | |

Detailed Description
A multiple-value field that contains any number of 4x4 matrices.
SoMFMatrices are written to file as sets of 16 floating point numbers separated by whitespace. When more than one value is present, all of the values are enclosed in square brackets and separated by commas; for example, two identity matrices might be written as:
[ 1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1,
1 0 0 0 0 1 0 0 0 0 1 0 0 0 0 1 ]
