Field Summary

Fields
Modifier and Type	Field and Description
`static byte`	`ON_CURVE` if set, the point is on the curve.
`static byte`	`REPEAT` if set, the next byte specifies the number of additional times this set of flags is to be repeated.
`static byte`	`X_DUAL` This flag as two meanings, depending on how the x-short vector flags is set.
`static byte`	`X_SHORT_VECTOR` if set, the x-coordinate is 1 byte long.
`static byte`	`Y_DUAL` This flag as two meanings, depending on how the y-short vector flags is set.
`static byte`	`Y_SHORT_VECTOR` if set, the y-coordinate is 1 byte long.

  - ON_CURVE
```
public static final byte ON_CURVE
```
    if set, the point is on the curve.

  - X_SHORT_VECTOR
```
public static final byte X_SHORT_VECTOR

  - REPEAT
```
public static final byte REPEAT
```
    if set, the next byte specifies the number of additional times this set of flags is to be repeated.

    Constant Field Values
  - X_DUAL
```
public static final byte X_DUAL
```
    This flag as two meanings, depending on how the x-short vector flags is set. If the x-short vector is set, this bit describes the sign of the value, with 1 equaling positive and 0 positive. If the x-short vector is not set and this bit is also not set, the current x-coordinate is a signed 16-bit delta vector.

    Constant Field Values
  - Y_DUAL
```
public static final byte Y_DUAL
```
    This flag as two meanings, depending on how the y-short vector flags is set. If the y-short vector is set, this bit describes the sign of the value, with 1 equaling positive and 0 positive. If the y-short vector is not set and this bit is also not set, the current y-coordinate is a signed 16-bit delta vector.
