Method Detail

getID

long getID()

Return the unique ID number of this geometry element.

Returns:

The unique ID of this geometry element.

getName

java.lang.String getName()

Return the name of this geometry element. If the name is not defined, then null is returned.

Returns:

The name of this geometry element.

setName

void setName(java.lang.String name)

Change the name of this geometry element to the specified name (may be null to clear the name and make it undefined).

Parameters:

name - The name of this geometry element.

size

int size()

Returns the number of child-elements that make up this geometry element.

Returns:

The number of child-elements that make up this geometry element.

toText

javolution.text.Text toText()

Returns the text representation of this geometry element.

Returns:

The text representation of this geometry element.

getPhyDimension

int getPhyDimension()

Returns the number of physical dimensions of this geometry element.

Returns:

The number of physical dimensions of this geometry element.

toDimension

T toDimension(int newDim)

Return a copy of this element converted to the specified number of physical dimensions. If the number of dimensions is greater than this element, then zeros are added to the additional dimensions. If the number of dimensions is less than this element, then the extra dimensions are simply dropped (truncated). If the new dimensions are the same as the dimension of this element, then this element is simply returned.

Parameters:

newDim - The dimension of the element to return.

Returns:

A copy of this geometry element converted to the new dimensions.

getParDimension

int getParDimension()

Returns the number of parametric dimensions of this geometry element.

Returns:

The number of parametric dimensions of this geometry element.

getBoundsMin

Point getBoundsMin()

Return the coordinate point representing the minimum bounding box corner of this geometry element (e.g.: min X, min Y, min Z).

Returns:

The minimum bounding box coordinate for this geometry element.

getBoundsMax

Point getBoundsMax()

Return the coordinate point representing the maximum bounding box corner of this geometry element (e.g.: max X, max Y, max Z).

Returns:

The maximum bounding box coordinate for this geometry element.

getLimitPoint

GeomPoint getLimitPoint(int dim,
                        boolean max,
                        double tol)

Returns the most extreme point, either minimum or maximum, in the specified coordinate direction on this geometry element. This is more accurate than getBoundsMax & getBoundsMin, but also typically takes longer to compute.

Parameters:

dim - An index indicating the dimension to find the min/max point for (0=X, 1=Y, 2=Z, etc).

max - Set to true to return the maximum value, false to return the minimum.

tol - Fractional tolerance to refine the min/max point position to if necessary.

Returns:

The point found on this element that is the min or max in the specified coordinate direction.

See Also:

getBoundsMin(), getBoundsMax()

isValid

boolean isValid()

Return true if this GeomElement contains valid and finite numerical components. A value of false will be returned if any of the evaluations of this element are NaN or Inf.

Returns:

true if this geometry element contains valid and finite data.

The unit in which the geometry in this element are stated.

to

T to(javax.measure.unit.Unit<javax.measure.quantity.Length> unit)
throws javax.measure.converter.ConversionException

Returns the equivalent to this element but stated in the specified unit.

Parameters:

unit - the length unit of the element to be returned.

Returns:

an equivalent to this element but stated in the specified unit.

Throws:

javax.measure.converter.ConversionException - if the the input unit is not a length unit.

Returns:

A copy of this object with any transformations removed (applied).

key - the key whose associated value is to be returned or null if the specified key could not be found.

Returns:

Any user defined data associated with this geometry and the specified key.

Throws:

java.lang.NullPointerException - if key is null.
