- Method Detail
  - detach
```
protected ECPoint detach()
```
    Specified by:
    
    detach in class ECPoint
  - getYCoord
```
public ECFieldElement getYCoord()
```
    Description copied from class: ECPoint
    
    Returns the y-coordinate. Caution: depending on the curve's coordinate system, this may not be the same value as in an affine coordinate system; use normalize() to get a point where the coordinates have their affine values, or use getAffineYCoord() if you expect the point to already have been normalized.
    
    Overrides:
    
    getYCoord in class ECPoint
    
    Returns:
    
    the y-coordinate of this point
