All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`double`	`getMedialScale(int level)`	Get a scale between the given zoom level and the next
`double`	`getScaleDenominator(int level)`	Find the reciprocal of the scale at a specified zoom level in this context.
`boolean`	`isInRange(int level)`	Is the given level within the range for which the context has clearly defined scales.

```
public static void validate(List<Double> scales)
```
    Checks if the list contains a decreasing sequence of finite, positive, non-null values.
    
    Throws:
    
    IllegalArgumentException - if the values are not decreasing, positive, and finite.
    
    NullPointerException - if any values are null.
  - getScaleDenominator
```
public double getScaleDenominator(int level)
```
    Description copied from interface: ZoomContext
    
    Find the reciprocal of the scale at a specified zoom level in this context.
    
    Parameters:
    
    level - The level
    
    Returns:
    
    The scale denominator
