Constructor Detail

ShortValues

public ShortValues()

construct a ShortValues with no data

ShortValues

public ShortValues(short[] shortArray)

construct a ShortValues for a given short array

ShortValues

public ShortValues(int size)

construct a ShortValues for a given short array with the given number of shorts. set initial values to 0

Method Detail

setData

public final void setData(int index,
                          short shortData)

set the data at given index

getStorageType

public int getStorageType()

get the storage type

Specified by:

getStorageType in class Values

size

public int size()

return the size of the 1 D array, in which the data is stored

Specified by:

size in class Values

reorder

public Values reorder(int step)

Return a new Values object with the values shuffled. This method starts at positions 0 through step-1, copying every "step" values to the new array. This has the effect of converting an attribute ordered array to a point ordered array or vice versa. The Values object does not actually need to know the axisOrdering, the conversion is the same.

Specified by:

reorder in class Values

getDoubles

public double[] getDoubles()

Return double array representing all elements in the Values object

Specified by:

getDoubles in class Values

getFloats

public float[] getFloats()

Return float array representing all elements in the Values object

Specified by:

getFloats in class Values

getInts

public int[] getInts()

Return int array representing all elements in the Values object

Specified by:

getInts in class Values

getShorts

public short[] getShorts()

return a reference to the array this ShortValues object is representing

Specified by:

getShorts in class Values

Return a byte array representing all elements in the Values object

Specified by:

getBytes in class Values

getDoubles

public double[] getDoubles(double[] filler)

fill the passed array with this data

Overrides:

getDoubles in class Values

getFloats

shortValues

public short[] shortValues()

Return a reference to the short data array this object contains. @deprecated. Use getDataReference()

getDataReference

public short[] getDataReference()

Return a reference to the data array this object contains.

getShorts

public short[] getShorts(int start,
                         int stride,
                         int num)

Return short array representing a subset of elements in the Values object Copying starts at the index specified by the start argument, the 2nd item copied will be at index start + stride where stride is the second argument; the 3rd is at start + 2*stride and so forth until the specified number of values have been copied (3rd argument). If there are not enough elements in the Values object to satisfy the request, the returned array will have only as many values as could be found given the start and stride arguments.

Overrides:

getShorts in class Values

spawn

public Values spawn()

create a copy of this object

Specified by:

spawn in class Values

spawn

public Values spawn(int start,
                    int stride,
                    int count)

Create a new instance of ShortValues with a subsest of the data in this object. Subsets can be contiguous or can have a stride as is done in point order storage. If there aren't "count" values to copy, the returned object will only be as large as the available values.

Specified by:

spawn in class Values

Parameters:

start - - first value to copy

stride - - steps between values

count - - number of values to copy

setDouble

Set the specified entry to the specified value after conversion, if needed.

Specified by:

setByte in class Values

setValues

public void setValues(Values newVals)

Assign the data from the argument Values object to this object. This object will now have a new data size that is the same as the arguments. (This version clones the data; do we want to just reference it?)

Specified by:

setValues in class Values

setValues

public void setValues(int start,
                      Values newVals)

Assign elements of the passed in Values object to this one beginning at the start index . Do conversions as needed. If the argument size is less than is available beginning at the start position, only the remaining values will be changed.
