Plan (The Adobe Experience Manager SDK 2023.7.12585.20230706T160730Z-230601)

```
public interface Plan
```
Describes graphics rendering operations with multiple layers.
A plan has the following structure, in order of execution:
- multiple layers (0..N) with individual commands (higher layers are merged onto lower layers)
- composition (layer commands applied after layers have been merged)
- view commands (define resulting image and file format)
Both the view and the layers implement the map-like interface in which instructions are set in a key-value style with keys being strings.

- Method Detail
  - view
```
Instructions view()
```
    Instruction regarding the output view of the rendering plan. Defines the output image format and other global flags.
    
    Returns:
    
    map containing view related instructions
  - layer
```
Layer layer(int index)
```
    Retrieve layers from 0 (lowest) to N (highest). The layer asked for and all yet missing layers in between will be added on the fly.
    
    Parameters:
    
    index - index of the layer to retrieve
    
    Returns:
    
    the layer at the given index, will be created if it does not exist yet
  - layers
```
java.util.List<Layer> layers()
```
    All layers of the plan.
    
    Returns:
    
    a modifiable list of all layers in the plan
  - composition
```
Layer composition()
```
    Returns the special composition layer. These are layer commands executed after all layers have been merged and before the output image is serialized.
    
    Returns:
    
    the special composition layer
  - toString
```
java.lang.String toString()
```
    Returns a single-line string representation of this plan for log and debug output.
    
    Overrides:
    
    toString in class java.lang.Object
    
    Returns:
    
    a single-line string representation of this plan
  - toJsonString
```
java.lang.String toJsonString()
```
    Returns a multi-line JSON representation of this plan.
    
    Returns:
    
    a multi-line JSON representation of this plan
