public class SoMFVec2d extends SoMField
Multiple-value field containing any number of two-dimensional vectors. A multiple-value field that contains any number of two-dimensional vectors.SoMFVec2ds are written to file as one or more pairs of double precision 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, 1.2 3.4, 98.6 -4e1 ] 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.

SoMFVec2d
public SoMFVec2d(SoFieldContainer fieldContainer, java.lang.String fieldName, SoField.FieldTypes fieldType)
Default constructor.

Method Detail
-
setValues
public void setValues(int start, int num, double[] xy)
Deprecated.As of Open Inventor 9.3.1, usesetValues(int, double[])
instead.Sets values from array of arrays of 2 doubles.
-
find
public int find(SbVec2d targetValue)
Calls find(targetValue, false).
-
getValues
public SbVec2d[] getValues(int start)
Returns a pointer into the array of values in the field, starting at index start. The values are read-only. See thestartEditing()
/finishEditing() methods for a way of modifying values in place.
-
find
public int find(SbVec2d 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).
-
getDirectValues
public java.nio.DoubleBuffer getDirectValues(int start)
Returns a pointer into the array of values in the field, starting at index start. The values are read-only. See thestartEditing()
/finishEditing() methods for a way of modifying values in place.
-
set1Value
public void set1Value(int index, double x, double y)
Sets one value from 2 doubles.
-
startEditing
public java.nio.DoubleBuffer 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 betweenstartEditing()
andfinishEditing()
(e.g.set1Value()
,setValue()
, etc.). Fields, engines or sensors connected to this field and sensors are not notified that this field has changed untilfinishEditing()
is called. CallingfinishEditing()
always sets theisDefault()
flag to false and informs engines and sensors that the field changed, even if none of the values actually were changed.
-
getValueAt
public SbVec2d getValueAt(int i)
-
finishEditing
public void finishEditing()
Indicates that batch edits have finished. SeestartEditing()
.
-
setValues
public void setValues(int start, SbVec2d[] 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.
-
setValue
public void setValue(double[] xy)
Sets to one value from 2 doubles in array.
-
setValue
public void setValue(double x, double y)
Sets to one value from 2 doubles.
-
set1Value
public void set1Value(int index, double[] xy)
Sets one value from 2 doubles in array.
-
setValues
public void setValues(int start, double[] xy)
Sets values from the specified array of doubles. The size of the array must be a multiple of 2.
-
setValue
public void setValue(SbVec2d 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, SbVec2d 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.
-
setValuesBuffer
public void setValuesBuffer(java.nio.ByteBuffer userData)
Sets the field to contain the values stored in userData. This data will not be copied into the field: it will be directly used by the field.
-
disableDeleteValues
public void disableDeleteValues()
Temporary disable value deleting.
