Method Detail

getMin

public double getMin(int dimension)

Description copied from interface: SpatialComparable

Returns the minimum coordinate at the specified dimension.

Specified by:

getMin in interface SpatialComparable

Parameters:

dimension - the dimension for which the coordinate should be returned, where 0 ≤ dimension < getDimensionality()

Returns:

the minimum coordinate at the specified dimension

getMax

public double getMax(int dimension)

Description copied from interface: SpatialComparable

Returns the maximum coordinate at the specified dimension.

Specified by:

getMax in interface SpatialComparable

Parameters:

dimension - the dimension for which the coordinate should be returned, where 0 ≤ dimension < getDimensionality()

Returns:

the maximum coordinate at the specified dimension

byteValue

public byte byteValue(int dimension)

Description copied from interface: NumberVector

Returns the value in the specified dimension as byte. Note: this might seem redundant with respect to getValue(dim).byteValue(), but usually this is much more efficient due to boxing/unboxing cost.

Specified by:

byteValue in interface NumberVector

Parameters:

dimension - the desired dimension, where 0 ≤ dimension < this.getDimensionality()

Returns:

the value in the specified dimension

floatValue

public float floatValue(int dimension)

Description copied from interface: NumberVector

Returns the value in the specified dimension as float. Note: this might seem redundant with respect to getValue(dim).floatValue(), but usually this is much more efficient due to boxing/unboxing cost.

Specified by:

floatValue in interface NumberVector

Parameters:

dimension - the desired dimension, where 0 ≤ dimension < this.getDimensionality()

Returns:

the value in the specified dimension

intValue

public int intValue(int dimension)

Description copied from interface: NumberVector

Returns the value in the specified dimension as int. Note: this might seem redundant with respect to getValue(dim).intValue(), but usually this is much more efficient due to boxing/unboxing cost.

Specified by:

intValue in interface NumberVector

Parameters:

dimension - the desired dimension, where 0 ≤ dimension < this.getDimensionality()

Returns:

the value in the specified dimension

shortValue

public short shortValue(int dimension)

Description copied from interface: NumberVector

Returns the value in the specified dimension as short. Note: this might seem redundant with respect to getValue(dim).shortValue(), but usually this is much more efficient due to boxing/unboxing cost.

Specified by:

shortValue in interface NumberVector

Parameters:

dimension - the desired dimension, where 0 ≤ dimension < this.getDimensionality()

Returns:

the value in the specified dimension
