parameter: defaultValue: optional default value
parameter: defaultValueMask: optional default value mask

## Protected Field: flags
Type: `int`

## Static Field: NO_FLAG
Type: `int`

Constant value: `0`
Description: No operand\-builder flags.

## Static Field: OPTIONAL
Type: `int`

Constant value: `268435456`
Description: Flag indicating that the operand may be omitted.

## Static Field: OPTIONAL_DEFAULT_VALUE
Type: `int`

Constant value: `0`
