Constructor Detail

FloatTupleArrayImpl

public FloatTupleArrayImpl(int dim,
                           int initialSize)

FloatTupleArrayImpl

public FloatTupleArrayImpl(int dim,
                           int initialSize,
                           float growFactor)

Construct an instance of initialSize.

Parameters:

dim - The tuple dimension.

initialSize - The initial size of the internal array.

growFactor - Factor to grow by when resizing is necessary.

Method Detail

add

public void add(float[][] values,
                int start,
                int num)

Add values. If there is not enough space for the number of values to be added the array is continually grown until there is room.

Specified by:

add in interface FloatTupleArray

Parameters:

values - Source array.

start - index in the source array to start at

num - number of values to add.

elements

public float[][] elements()

Reference to the backing data array. Any changes made to this array will be reflected in the actual data.

Specified by:

elements in interface FloatTupleArray

Returns:

This may return a reference or copy depending on the implementation.

add

public void add(float[][] values)

Add values. If there is not enough space for the number of values to be added the array is continually grown until there is room.

Specified by:

add in interface FloatTupleArray

Parameters:

values - Source array.

set

public void set(int i,
                int j,
                float val)

Set a value.

Specified by:

set in interface FloatTupleArray

Parameters:

i - dimension index of the values to set

j - tuple index of the value to set

val - the value

get

public float[] get(int idx)

Get a tuple.

Parameters:

idx - The index of the tuple

Returns:

an array of the tuple values at the provided index.

get

public float get(int i,
                 int j)

Get a value.

Specified by:

get in interface FloatTupleArray

Parameters:

i - dimension index

j - tuple index.

Returns:

The value for tuple i at tuple index j.

toArray

public float[][] toArray()

Get contained data as array. The size of the array is exactly the size of the data.

NOTE: This is an expensive operation.

Specified by:

toArray in interface FloatTupleArray

Returns:

A copy of the array data.

size

public int size()

Get the size of the valid data.

Specified by:

size in interface FloatTupleArray

Returns:

size of array

dim

public int dim()

Get the dimension of the tuple.

Specified by:

dim in interface FloatTupleArray

Returns:

The array tuple dimension
