public class SoMFBufferObject
extends SoMField

Multiple-value field containing any number of buffer objects. This field maintains a set of SoBufferObject instances.

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 Details

SoMFBufferObject

public SoMFBufferObject(SoFieldContainer fieldContainer,
 String fieldName,
 SoField.FieldTypes fieldType)

Default constructor.

Method Details

find

public int find(SoBufferObject targetValue)

Calls find(targetValue, false).

set1Value

public void set1Value(int index,
 SoBufferObject 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.

equals

public boolean equals(Object obj)

Overrides:

equals in class SoField

disableDeleteValues

public void disableDeleteValues()

Temporary disable value deleting.

setValue

public void setValue(SoBufferObject 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.

find

public int find(SoBufferObject 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).

setValues

public void setValues(int start,
 SoBufferObject[] 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.

getValueAt

public SoBufferObject getValueAt(int i)
