Method Detail

isNormalized

public abstract boolean isNormalized()

Deprecated.

isFixedPoint

public abstract boolean isFixedPoint()

Deprecated.

normalize

public abstract LatLng normalize()

Deprecated.

getFixedLat

public abstract int getFixedLat()

Deprecated.

getFixedLng

public abstract int getFixedLng()

Deprecated.

getLat

public abstract double getLat()

Deprecated.

getLng

public abstract double getLng()

Deprecated.

copy

public abstract LatLng copy()

Deprecated.

toFixed

public abstract FixedLatLng toFixed()

Deprecated.

toFloat

public abstract FloatLatLng toFloat()

Deprecated.

toCartesian

public CartesianPoint toCartesian()

Deprecated.

Convert the lat/lng into the cartesian coordinate plane such that all world coordinates are represented in the first quadrant. The x dimension corresponds to latitude and y corresponds to longitude. The translation starts with the normalized latlng and adds 180 to the latitude and 90 to the longitude (subject to fixed point scaling).

fromCartesian

public static LatLng fromCartesian(CartesianPoint pt)

Deprecated.

The inverse of toCartesian(). Always returns a FixedLatLng.

Parameters:

pt -

arcDistance

public double arcDistance(LatLng ll2)

Deprecated.

Calculates the distance between two lat/lng's in miles. Imported from mq java client.

Parameters:

ll2 - Second lat,lng position to calculate distance to.

Returns:

Returns the distance in miles.

arcDistance

public double arcDistance(LatLng ll2,
                 DistanceUnits lUnits)

Deprecated.

Calculates the distance between two lat/lng's in miles or meters. Imported from mq java client. Variable references changed to match.

Parameters:

ll2 - Second lat,lng position to calculate distance to.

lUnits - Units to calculate distance, defaults to miles

Returns:

Returns the distance in meters or miles.

toString

public String toString()

Deprecated.

Overrides:

toString in class Object

calculateMidpoint

public abstract LatLng calculateMidpoint(LatLng other)

Deprecated.

Calculate the midpoint between this point an another. Respects fixed vs floating point

Parameters:

other -

hashCode

public abstract int hashCode()

Deprecated.

Overrides:

hashCode in class Object

equals

public abstract boolean equals(Object obj)

Deprecated.

Overrides:

equals in class Object
