Constructor Detail

FloatVariableAxis

public FloatVariableAxis(float[] edges)

Constructs and returns an axis with the given bin edges. Example: edges = (0.2, 1.0, 5.0) yields an axis with 2 in-range bins [0.2,1.0), [1.0,5.0) and 2 extra bins [-inf,0.2), [5.0,inf].

Parameters:

edges - the bin boundaries the partition shall have; must be sorted ascending and must not contain multiple identical elements.

Throws:

IllegalArgumentException - if edges.length < 1.

Method Detail

binCentre

public float binCentre(int index)

Description copied from interface: FloatIAxis

Centre of the bin specified.

Specified by:

binCentre in interface FloatIAxis

Parameters:

index - Bin number (0...bins()-1) or OVERFLOW or UNDERFLOW.

binLowerEdge

public float binLowerEdge(int index)

Description copied from interface: FloatIAxis

Lower edge of the specified bin.

Specified by:

binLowerEdge in interface FloatIAxis

Parameters:

index - Bin number (0...bins()-1) or OVERFLOW or UNDERFLOW.

Returns:

the lower edge of the bin; for the underflow bin this is Float.NEGATIVE_INFINITY.

bins

public int bins()

Description copied from interface: FloatIAxis

The number of bins (excluding underflow and overflow) on the axis.

Specified by:

bins in interface FloatIAxis

binUpperEdge

public float binUpperEdge(int index)

Description copied from interface: FloatIAxis

Upper edge of the specified bin.

Specified by:

binUpperEdge in interface FloatIAxis

Parameters:

index - Bin number (0...bins()-1) or OVERFLOW or UNDERFLOW.

Returns:

the upper edge of the bin; for the overflow bin this is Float.POSITIVE_INFINITY.

binWidth

public float binWidth(int index)

Description copied from interface: FloatIAxis

Width of the bin specified.

Specified by:

binWidth in interface FloatIAxis

Parameters:

index - Bin number (0...bins()-1) or OVERFLOW or UNDERFLOW.

coordToIndex

public int coordToIndex(float coord)

Description copied from interface: FloatIAxis

Converts a coordinate on the axis to a bin number. If the coordinate is < lowerEdge returns UNDERFLOW, and if the coordinate is >= upperEdge returns OVERFLOW.

Specified by:

coordToIndex in interface FloatIAxis

lowerEdge

public float lowerEdge()

Description copied from interface: FloatIAxis

Lower axis edge.

Specified by:

lowerEdge in interface FloatIAxis

upperEdge

public float upperEdge()

Description copied from interface: FloatIAxis

Upper axis edge.

Specified by:

upperEdge in interface FloatIAxis
