Methods
  NameDescription
Public methodAppendConnection(SoEngineOutput)

Appends this field to the list of connections from another engineOutput.

(Inherited from SoField.)
Public methodAppendConnection(SoField)

Appends this field to the list of connections from another field.

Connects this field to another field.

(Inherited from SoField.)

Copy from another field of same type.

Public methodDeleteValues(Int32)
Calls DeleteValues(start, -1).
(Inherited from SoMField.)
Public methodDeleteValues(Int32, Int32)

Deletes num values beginning at index start (index start through start + num -1 will be deleted, and any leftover values will be moved down to fill in the gap created).

(Inherited from SoMField.)

(Inherited from SoField.)
Public methodEnableConnection

Field connections may be enabled and disabled.

(Inherited from SoField.)
Public methodEquals
Public methodFind(SbVec2s)
Calls Find(targetValue, false).
Public methodFind(SbVec2s, Boolean)

Finds the given targetValue in the array and returns the index of that value.

Public methodFinishEditing

Indicates that batch edits have finished.

Public methodGet

Returns the value of the field in the Open Inventor file format, even if the field has its default value.

(Inherited from SoField.)
Public methodGet1

This is equivalent to the OIV.Inventor.Fields.SoField.Get(System.String@) method of OIV.Inventor.Fields.SoField, but operates on only one value.

(Inherited from SoMField.)
Public methodGetConnectedEngine

Returns true if this field is being written into by an engine, and returns the engine output it is connected to in engineOutput.

(Inherited from SoField.)
Public methodGetConnectedField

Returns true if this field is being written into by another field, and returns the field it is connected to in writingField.

(Inherited from SoField.)
Public methodGetConnections

Returns a list of the connections to this field.

(Inherited from SoField.)
Public methodGetContainer

Returns the object that contains this field.

(Inherited from SoField.)
Public methodGetForwardConnections

Adds references 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.

(Inherited from SoField.)
Public methodGetHashCode
Overrides GetHashCode().
(Inherited from SoNetBase.)
Public methodGetNum Obsolete.

Returns the number of values currently in the field.

(Inherited from SoMField.)
Public methodGetNumConnections

Returns the number of connections to this field.

(Inherited from SoField.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodGetValues

Returns a pointer into the array of values in the field, starting at index start.

Public methodGetValueSize

Gets the size of the value.

(Inherited from SoField.)
Public methodInsertSpace

Inserts space for num values at index start .

(Inherited from SoMField.)
Public methodIsConnected

Returns true if the field is connected to anything.

(Inherited from SoField.)
Public methodIsConnectedFromEngine

Returns true if the field is connected to an engine's output.

(Inherited from SoField.)
Public methodIsConnectedFromField

Returns true if the field is connected to another field.

(Inherited from SoField.)
Public methodIsConnectedFromVRMLInterp

Returns true if the field is connected to a VRML interpOutput.

(Inherited from SoField.)
Public methodIsConnectionEnabled

Returns false if connections to this field are disabled.

(Inherited from SoField.)
Public methodIsDefault

Gets the state of default flag of the field.

(Inherited from SoField.)
Public methodIsIgnored

Gets the ignore flag for this field.

(Inherited from SoField.)
Public methodSet

Sets the field to the given value, which is an ASCII string in the Open Inventor file format.

(Inherited from SoField.)
Public methodSet1

This is equivalent to the OIV.Inventor.Fields.SoField.Set(System.String) method of OIV.Inventor.Fields.SoField, but operates on only one value.

Remarks

A multiple-value field that contains any number of two-dimensional vectors.

SoMFVec2ss are written to file as one or more pairs of short values 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:

   [ 0 0, 1 3, 100 17 ]

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 OIV.Inventor.Fields.SoMFVec3f for more information and example code.
