public DoubleArrayField(Node owner,
                        java.lang.String name,
                        int usage,
                        double[] value)

Parameters:

owner - this Field's owner

name - this Field's name

usage - this Field's usage

value - this Field's value

Method Detail

getLength

public int getLength()

Returns the number of elements in the array of values.

Returns:

the number of elements

Overrides:

getLength in class ArrayField

set1Value

public void set1Value(int index,
                      double newVal)
               throws Shout3DException

Sets a single value in the array from the input newVal. If the specified index is out of range, throws a Shout3DException. Otherwise, sets the value and notifies all registered FieldObservers.

Parameters:

index - the index of the element in the array to be set

newVal - the new value for the given element of the field

setValue

public void setValue(double[] newVal)

Sets the value of the field from the input argument. Does not create a copy of the input, but refers to the same array in memory. Following this, notifies all registered FieldObservers.

Parameters:

newVal - the new value for the field

getValue

public double[] getValue()

Returns the current value of the field as a reference to the array. Returns a reference to the actual value of the field, not a copy. If an application changes the data, it must notify the field by making a subsequent call to setValue.

Returns:

the reference to the value

setValueByString

public void setValueByString(java.lang.String string)

Overrides:

setValueByString in class Field

getValueByString

public java.lang.String getValueByString()

Overrides:

getValueByString in class Field
