Interface Plan

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 Summary

Modifier and Type	Method and Description
Layer	composition() Returns the special composition layer.
Layer	layer(int index) Retrieve layers from 0 (lowest) to N (highest).
java.util.List<Layer>	layers() All layers of the plan.
java.lang.String	toJsonString() Returns a multi-line JSON representation of this plan.
java.lang.String	toString() Returns a single-line string representation of this plan for log and debug output.
Instructions	view() Instruction regarding the output view of the rendering plan.

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
