All Implemented Interfaces:

Cloneable

Enclosing class:

ProductData

public static class ProductData.UShort
extends ProductData.Short

The UShort class is a ProductData specialisation for unsigned 16-bit integer fields.

Internally, data is stored in an array of the type short[].

In order to preserve the accuracy for the unsigned byte value range the getElemIntAt method should be used to retrieve the data stored in this value instead of accessing the data array directly.

Another method is to mask each of the array elements in order to get the unsigned type in the following way:

     short[] data = (short[]) value.getRaster();
     for (int i = 0; i < data.length; i++) {
         int value = data[i] & 0xffff;
         ...
     }

Constructor Details

UShort

public UShort(int numElems)

Constructs a new unsigned short value.

Parameters:

numElems - the number of elements, must not be less than one

UShort

public UShort(short[] array)

Constructs a new unsigned short value.

Parameters:

array - the elements

Method Details

createDeepClone

protected ProductData createDeepClone()

Retuns a "deep" copy of this product data.

Overrides:

createDeepClone in class ProductData.Short

Returns:

a copy of this product data

getElemIntAt

public int getElemIntAt(int index)

Please refer to ProductData.getElemIntAt(int).

Overrides:

getElemIntAt in class ProductData.Short

Parameters:

index - the value index, must be >=0 and <getNumDataElems()

getElemUIntAt

public long getElemUIntAt(int index)

Please refer to ProductData.getElemUIntAt(int).

Overrides:

getElemUIntAt in class ProductData.Short

Parameters:

index - the value index, must be >=0 and <getNumDataElems()

getElemFloatAt

public float getElemFloatAt(int index)

Please refer to ProductData.getElemFloatAt(int).

Overrides:

getElemFloatAt in class ProductData.Short

Parameters:

index - the value index, must be >=0 and <getNumDataElems()

getElemDoubleAt

public double getElemDoubleAt(int index)

Please refer to ProductData.getElemDoubleAt(int).

Overrides:

getElemDoubleAt in class ProductData.Short

Parameters:

index - the value index, must be >=0 and <getNumDataElems()

getElemStringAt

public String getElemStringAt(int index)

Parameters:

index - the value index, must be >=0 and <getNumDataElems()

setElems

public void setElems(Object data)

Sets the data of this value. The data must be an array of the type short[] or String[] and have a length that is equal to the value returned by the getNumDataElems method.

Overrides:

setElems in class ProductData.Short

Parameters:

data - the data array

Throws:

IllegalArgumentException - if data is null or it is not an array of the required type or does not have the required array length.
