## Detailed Description

Description of a RangeParameter.

## Constructor & Destructor Documentation

RangeParameter | ( | const ParameterInfo & | paramInfo,
|  | ParamValue | min,
|  | ParamValue | max
| ) |  |

RangeParameter | ( | const TChar * | title,
|  | ParamID | tag,
|  | const TChar * | units = `nullptr`,
|  | ParamValue | minPlain = `0.`,
|  | ParamValue | maxPlain = `1.`,
|  | ParamValue | defaultValuePlain = `0.`,
|  | int32 | stepCount = `0`,
|  | int32 | flags = `ParameterInfo::kCanAutomate`,
|  | UnitID | unitID = `kRootUnitId`,
|  | const TChar * | shortTitle = `nullptr`
| ) |  |

## Member Function Documentation

virtual ParamValue getMin | ( |  | ) | const
| inline virtual

Gets the minimum plain value, same as toPlain (0).

virtual void setMin | ( | ParamValue | value | ) |
| inline virtual

Sets the minimum plain value.

virtual ParamValue getMax | ( |  | ) | const
| inline virtual

Gets the maximum plain value, same as toPlain (1).

virtual void setMax | ( | ParamValue | value | ) |
| inline virtual

Sets the maximum plain value.

void toString | ( | ParamValue | _valueNormalized,
|  | String128 | string
| ) |  | const
| virtual

Converts a normalized value to a string.

Reimplemented from Parameter.

bool fromString | ( | const TChar * | string,
|  | ParamValue & | _valueNormalized
| ) |  | const
| virtual

Converts a string to a normalized value.

Reimplemented from Parameter.

ParamValue toPlain | ( | ParamValue | _valueNormalized | ) | const
| virtual

Converts a normalized value to plain value (e.g.

0.5 to 10000.0Hz).

Reimplemented from Parameter.

ParamValue toNormalized | ( | ParamValue | plainValue | ) | const
| virtual

Converts a plain value to a normalized value (e.g.

10000 to 0.5).

Reimplemented from Parameter.
