Constructor Detail

TransitCalculator

public TransitCalculator()

Method Detail

getRollover

public abstract boolean getRollover()

Returns:

Returns true, if one position value is identical to another position value. E.g., 360 degree is identical to 0 degree in circular angles.

See Also:

rolloverVal

getRolloverVal

public double getRolloverVal()

Returns:

Returns the value, which is identical to zero on the other end of a linear scale.

See Also:

rolloverVal

getMinOffset

public double getMinOffset()

Returns:

Returns the lowest possible offset value.

getMaxOffset

public double getMaxOffset()

Returns:

Returns the highest possible offset value.

setOffset

public abstract void setOffset(double value)

This sets the degree or other value for the position or speed of the planet to transit. It will be used on the next call to getTransit().

Parameters:

value - The desired offset value.

See Also:

getOffset()

getOffset

public abstract double getOffset()

This returns the degree or other value of the position or speed of the planet to transit.

Returns:

The currently set offset value.

See Also:

setOffset(double)

getObjectIdentifiers

public java.lang.Object[] getObjectIdentifiers()

This returns all the "object identifiers" used in this TransitCalculator. It may be the planet number or planet numbers, when calculating planets.

Returns:

An array of identifiers identifying the calculated objects.

getMaxSpeed

protected abstract double getMaxSpeed()

getMinSpeed
