Record Class RelativePosition

java.lang.Object

java.lang.Record

org.opentrafficsim.core.gtu.RelativePosition

Record Components:

dx - Length; positive x is in the normal direction of movement.

dy - Length; positive y is left compared to the normal direction of movement (seen from the top).

dz - Length; positive z is up.

type - TYPE; type of relative position (FRONT, BACK, etc.).

All Implemented Interfaces:

Serializable

public record RelativePosition(org.djunits.value.vdouble.scalar.Length dx, org.djunits.value.vdouble.scalar.Length dy, org.djunits.value.vdouble.scalar.Length dz, RelativePosition.Type type)
extends Record
implements Serializable

A RelativePosition is a position on a GTU; e.g. the front, rear, position of the driver, etc.
A RelativePosition stores the offset of the position from the reference position of the GTU.

Constructor Details

RelativePosition

public RelativePosition(RelativePosition p)

Parameters:

p - RelativePosition; a relative position to make a deep copy of.

RelativePosition

public RelativePosition(org.djunits.value.vdouble.scalar.Length dx,
 org.djunits.value.vdouble.scalar.Length dy,
 org.djunits.value.vdouble.scalar.Length dz,
 RelativePosition.Type type)

Creates an instance of a RelativePosition record class.

Parameters:

dx - the value for the dx record component

dy - the value for the dy record component

dz - the value for the dz record component

type - the value for the type record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

dx

public org.djunits.value.vdouble.scalar.Length dx()

Returns the value of the dx record component.

Returns:

the value of the dx record component

dy

public org.djunits.value.vdouble.scalar.Length dy()

Returns the value of the dy record component.

Returns:

the value of the dy record component

dz

public org.djunits.value.vdouble.scalar.Length dz()

Returns the value of the dz record component.

Returns:

the value of the dz record component

type

public RelativePosition.Type type()

Returns the value of the type record component.

Returns:

the value of the type record component
