Method Detail

create

public static IdentityTranslation create(int i)

getMatrixComponent

public AMatrix getMatrixComponent()

Specified by:

getMatrixComponent in class AAffineTransform

getTranslationComponent

public ATranslation getTranslationComponent()

Specified by:

getTranslationComponent in class AAffineTransform

transform

public void transform(AVector source,
             AVector dest)

Description copied from class: ATransform

Transforms the source vector, storing the result in the given destination vector

Specified by:

transform in interface ITransform

Overrides:

transform in class ATranslation

transform

public Vector transform(AVector source)

Description copied from class: ATransform

Transforms a vector, returning a new transformed vector

Overrides:

transform in class ATransform

Returns:

transformInPlace

public void transformInPlace(AVector v)

Description copied from class: ATransform

Transforms a vector destructively. Intended for fast non-allocating transforms

Overrides:

transformInPlace in class ATranslation

calculateElement

public double calculateElement(int i,
                      AVector v)

Description copied from class: ATransform

Calculates a single element of the output. Not necessarily faster than calculating full output, but can be in some circumstances.

Overrides:

calculateElement in class ATranslation

isIdentity

public boolean isIdentity()

Description copied from class: ATranslation

Returns true if this transform is an identity transform

Overrides:

isIdentity in class ATranslation

inputDimensions

public int inputDimensions()

Description copied from class: ATransform

Returns the number of dimensions required for input vectors

Specified by:

inputDimensions in interface ITransform

Specified by:

inputDimensions in class ATransform

Returns:

outputDimensions

public int outputDimensions()

Description copied from class: ATransform

Returns the number of dimensions required for output vectors

Specified by:

outputDimensions in interface ITransform

Specified by:

outputDimensions in class ATransform

Returns:

getTranslationVector

public AVector getTranslationVector()

Description copied from class: ATranslation

Gets the vector offset that this translation represents. Not guaranteed to be a reference.

Specified by:

getTranslationVector in class ATranslation

Returns:

hashCode

public int hashCode()

Overrides:

hashCode in class ATranslation
