Method Detail

isVertical

public boolean isVertical()

Description copied from class: LinearTransformation

Returns whether this is a vertical transformation.

Specified by:

isVertical in class LinearTransformation

isHorizontal

public boolean isHorizontal()

Description copied from class: LinearTransformation

Returns whether this is a horizontal transformation.

Specified by:

isHorizontal in class LinearTransformation

slope

public double slope()

Description copied from class: LinearTransformation

Returns the slope of the transformation, i.e. the rate of change of y with respect to x. This must not be called on a vertical transformation (i.e. when LinearTransformation.isVertical() is true).

Specified by:

slope in class LinearTransformation

transform

public double transform(double x)

Description copied from class: LinearTransformation

Returns the y corresponding to the given x. This must not be called on a vertical transformation (i.e. when LinearTransformation.isVertical() is true).

Specified by:

transform in class LinearTransformation

inverse

public LinearTransformation inverse()

Description copied from class: LinearTransformation

Returns the inverse linear transformation. The inverse of a horizontal transformation is a vertical transformation, and vice versa. The inverse of the LinearTransformation.forNaN() transformation is itself. In all other cases, the inverse is a transformation such that applying both the original transformation and its inverse to a value gives you the original value give-or-take numerical errors. Calling this method multiple times on the same instance will always return the same instance. Calling this method on the result of calling this method on an instance will always return that original instance.

toString

public java.lang.String toString()
