Method Detail

isXZero

public final boolean isXZero()

Checks if the X coordinate is zero.

Returns:

return true if and only if the X coordinate is zero

isYZero

public final boolean isYZero()

Checks if the Y coordinate is zero.

Returns:

return true if and only if the Y coordinate is zero

isZero
