com.storedobject.svg.Node<G>

com.storedobject.svg.Element<G>

com.storedobject.svg.AbstractGroup<G>

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

Bar, Group

public abstract class AbstractGroup<G extends AbstractGroup<G>>
extends Element<G>

Abstract base class representing an SVG group element. This class is used to manage and organize a collection of Node elements within an SVG structure. It provides functionality for handling child nodes, computing their bounding coordinates, and generating the inner SVG content for the group.

Subclasses of AbstractGroup can extend and define additional behavior or functionality specific to their use case while leveraging group-based organization in an SVG document.

Field Details

children

protected final List<Node<?>> children

A list that stores the child Node elements contained within this group. It is used to manage and organize the hierarchical structure of the SVG group element. The children list can contain zero or more Node objects, representing the child elements nested under this group.

This field is immutable, meaning the reference to the list itself cannot be changed. However, the contents of the list (i.e., the child Node elements) can be modified by adding or removing items to the list. The order of elements in the list defines their rendering order in the SVG output.

Constructor Details

AbstractGroup

public AbstractGroup()

Method Details

children

public Stream<Node<?>> children()

Retrieves a stream of child Node elements that are part of this group. The returned stream provides a way to access and process the children sequentially or in parallel.

Returns:

a Stream of Node elements representing the children of this group.

compute

protected void compute()

Description copied from class: Node

This method is invoked to perform any necessary computations just before the SVG content is generated.

Note: At least coordinates values should be set here properly.

Overrides:

compute in class Node<G extends AbstractGroup<G>>

innerContent

protected String innerContent()

Description copied from class: Node

Retrieves the inner content of the node. This method is typically implemented or overridden by subclasses to provide specific content representing the inner state or structure of the node.

Overrides:

innerContent in class Node<G extends AbstractGroup<G>>

Returns:

A string containing the inner content of the node, or null if no content is defined.
