protected long[] longElementValues

Holds the values of this array value's long value elements. Non-null if there is at least one long value element.

floatElementValues

protected float[] floatElementValues

Holds the values of this array value's float value elements. Non-null if there is at least one float value element.

doubleElementValues

protected double[] doubleElementValues

Holds the values of this array value's double value elements. Non-null if there is at least one double value element.

Constructor Detail

UniformValueArray

protected UniformValueArray(IValueFactory valueFactory,
                            IValue[] elementValues)

Default constructor.

Parameters:

valueFactory - The value factory for this value array. Needed to create IPrimitiveValue to implement getElementValue since we store each primitive value by its corresponding ava primitive values.

elementValues - The element values for this value array. Must be non-null. Each element must be non-null.

UniformValueArray

protected UniformValueArray()

Private constructor for cloning purposes.

Method Detail

setElementValue

public void setElementValue(int elementIndex,
                            IValue elementValue)

Description copied from interface: IValueArray

Sets a value array element's value.

Specified by:

setElementValue in interface IValueArray

Parameters:

elementIndex - The index of the element in this value array. Must be greater than zero and less than the length of this value array.

elementValue - The new value of the element. Must be non-null.

getElementValue

public IValue getElementValue(int elementIndex)

Description copied from interface: IValueArray

Gets a value array element's value.

Specified by:

getElementValue in interface IValueArray

Parameters:

elementIndex - The index of the element in this value array. Must be greater than zero and less than the length of this value array.

Returns:

The element's array value. Non-null.

getLength

public int getLength()

Description copied from interface: IValueArray

Gets the length of this value array.

Specified by:

getLength in interface IValueArray

Returns:

The length of this value array. At least zero.

clone

public IValueArray clone(boolean deepClone,
                         Map<Object,Object> cloneMap)

Description copied from interface: IValueArray

Clone this value array.

Specified by:

clone in interface IValueArray

Parameters:

deepClone - Indicates whether deep cloning.

cloneMap - Original values (IValue) to their clones ( IValue) mapping. The clone map to solve circular references in values. If this value is a key in the map, then this method returns the value of the key in the map. Must be non-null if deep cloning.

Returns:

The clone this value array.

dispose

public void dispose()
