Constructor Detail

FloatValues

public FloatValues()

construct a FloatValues with no data

FloatValues

public FloatValues(float[] floatArray)

construct a FloatValues for a given float array

FloatValues

public FloatValues(int size)

construct a FloatValues for a given float array with the given number of floats.

Method Detail

setData

public final void setData(int index,
           float floatData)

set the data at given index NEW NEW NEW

getStorageType

public int getStorageType()

return the storageType of this FloatValues, The data type of the array used to store the actual data

Specified by:

getStorageType in class Values

size

public int size()

retrun 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 a reference to the float array this object is representing

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 short array representing all elements in the Values object

Specified by:

getShorts in class Values

getBytes

public byte[] getBytes()

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

public float[] getFloats(float[] filler)

fill the passed array with this data

Overrides:

getFloats in class Values

getInts

public int[] getInts(int[] filler)

fill the passed array with this data

Overrides:

getShorts

public short[] getShorts(short[] filler)

fill the passed array with this data

Overrides:

getBytes

public byte[] getBytes(byte[] filler)

fill the passed array with this data

Overrides:

getFloat

public float getFloat(int index)

return the float value at the given index of the array

Specified by:

getFloat in class Values

getInt

public int getInt(int index)

return the int value of the float at the given index of the float array

Specified by:

getShort

public short getShort(int index)

return the short value of the float at the given index of the float array

Specified by:

public float[] floatValues()

Deprecated. Use getDataReference()

Return a reference to the float data array this object contains.

getDataReference

public float[] getDataReference()

Return a reference to the data array this object contains.

getFloats

public float[] getFloats(int start,
                int stride,
                int num)

Return float 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:

getFloats in class Values

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 FloatValues 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
