public class SoMFFloat
extends SoMField

Multiple-value field containing any number of floating point values. A multiple-value field that contains any number of floating point values.

SoMFFloats are written to file as one or more values in standard scientific notation. When more than one value is present, all of the values are enclosed in square brackets and separated by commas; for example:

   [ 1.0, 2.3, 5, 6.2e4, -100, ]

The last comma is optional.

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.

Constructor Detail

SoMFFloat

public SoMFFloat(SoFieldContainer fieldContainer,
                 java.lang.String fieldName,
                 SoField.FieldTypes fieldType)

Default constructor.

Method Detail

find

public int find(float targetValue)

Calls find(targetValue, false).

getValueAt

public float getValueAt(int i)

finishEditing

public void finishEditing()

Indicates that batch edits have finished. See startEditing().

startEditing

public java.nio.FloatBuffer 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 between startEditing() and finishEditing() (e.g. set1Value(), setValue(), etc.). Fields, engines or sensors connected to this field and sensors are not notified that this field has changed until finishEditing() is called. Calling finishEditing() always sets the isDefault() flag to false and informs engines and sensors that the field changed, even if none of the values actually were changed.

disableDeleteValues

public void disableDeleteValues()

Temporary disable value deleting.

setValue

public void setValue(float 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,
                      float 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.

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class SoField

getValues

public float[] getValues(int start)

Returns a pointer into the array of values in the field, starting at index start. The values are read-only. See the startEditing()/finishEditing() methods for a way of modifying values in place.

getDirectValues

public java.nio.FloatBuffer getDirectValues(int start)

Returns a pointer into the array of values in the field, starting at index start. The values are read-only. See the startEditing()/finishEditing() methods for a way of modifying values in place.

setValues

public void setValues(int start,
                      float[] 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(float 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).
