MultiCascade (JOSM)

java.lang.Object
- org.openstreetmap.josm.gui.mappaint.MultiCascade

All Implemented Interfaces:

StyleKeys
```
public class MultiCascade
extends java.lang.Object
implements StyleKeys
```
Several layers / cascades, e.g. one for the main Line and one for each overlay. The range is (0,Infinity) at first and it shrinks in the process when StyleSources apply zoom level dependent properties.

```
public Cascade getOrCreateCascade(java.lang.String layer)
```
    Return the cascade with the given name. If it doesn't exist, create a new layer with that name and return it. The new layer will be a clone of the "*" layer, if it exists.
    
    Parameters:
    
    layer - layer
    
    Returns:
    
    cascade
  - getCascade
```
public Cascade getCascade(java.lang.String layer)
```
    Read-only version of getOrCreateCascade(java.lang.String). For convenience, it returns an empty cascade for non-existing layers. However this empty (read-only) cascade is not added to this MultiCascade object.
    
    Parameters:
    
    layer - layer
    
    Returns:
    
    cascade
  - getLayers
```
public java.util.Collection<java.util.Map.Entry<java.lang.String,Cascade>> getLayers()
```
    Gets all cascades for the known layers
    
    Returns:
    
    The cascades for the layers
  - hasLayer
```
public boolean hasLayer(java.lang.String layer)
```
    Check whether this cascade has a given layer
    
    Parameters:
    
    layer - The layer to check for
    
    Returns:
    
    true if it has that layer
