Method Detail

toString

public String toString()

Overrides:

toString in class Object

copy

public CellKey.Two copy()

Description copied from interface: CellKey

Returns a mutable copy of this CellKey.

Specified by:

copy in interface CellKey

Returns:

Mutable copy

getOffset

public int getOffset(int[] axisMultipliers)

Description copied from interface: CellKey

Returns the offset of the cell in a raster-scan order.

For example, if the axes have lengths {2, 5, 10} then cell (2, 3, 4) has offset

(2 * mulitiplers[0]) + (3 * multipliers[1]) + (4 * multipliers[2])
= (2 * 50) + (3 * 10) + (4 * 1)
= 134

The multipliers are the product of the lengths of all later axes, in this case (50, 10, 1).

Specified by:

getOffset in interface CellKey

Parameters:

axisMultipliers - For each axis, the product of the lengths of later axes

Returns:

The raster-scan ordinal of this cell

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

size

public int size()

Description copied from interface: CellKey

Returns the number of axes.

Specified by:

size in interface CellKey

Returns:

number of axes

getOrdinals

public int[] getOrdinals()

Description copied from interface: CellKey

Returns the axis keys as an array.

Note: caller should treat the array as immutable. If the contents of the array are modified, behavior is unspecified.

Specified by:

getOrdinals in interface CellKey

Returns:

Array of axis keys

setOrdinals

public void setOrdinals(int[] pos)

Description copied from interface: CellKey

This method make a copy of the int array parameter. Throws a RuntimeException if the int array size is not the size of the CellKey.

Specified by:

setOrdinals in interface CellKey

Parameters:

pos - Array of axis keys

getAxis

public int getAxis(int axis)

Description copied from interface: CellKey

Returns the axisth axis value.

Specified by:

getAxis in interface CellKey

Parameters:

axis - Axis ordinal

Returns:

Value of the axisth axis

setAxis

public void setAxis(int axis,
                    int value)

Description copied from interface: CellKey

Sets a given axis.

Specified by:

setAxis in interface CellKey

Parameters:

axis - Axis ordinal

value - Value
