Lib-Tag

Intention

The sublibrary Lib-Tag-Core contains the core functionalities to perform the CRUD (Create, Read, Update and Delete) operations for a Tag.

A Tag is a simple String which can be used for example in a Button, Label or another JavaFX components. Suchlike tagged topics can be easily searched or analyzed for a Tag.

The UML diagram is created with the Online Modeling Platform GenMyModel.

Usage of the class TagBuilder

It is very easy to create a Tag with the fluent builder TagBuilder:

/**
 * With the fluent builder {@code Class} {@link com.github.naoghuman.lib.tag.core.TagBuilder} 
 * the developer can easily create an instance from the {@code Interface} 
 * {@link com.github.naoghuman.lib.tag.core.Tag}.
 * <ul>
 * <li>The first two attributes {@code id} and {@code title} are mandory.</li>
 * <li>All other attributes are optional, that means skipping them returns {@link java.util.Optional#empty()}.</li>
 * <li>Any attribute (mandory or optional if set) will be validate against {@link com.github.naoghuman.lib.tag.internal.DefaultTagValidator}.</li>
 * </ul>

 */
final Tag tag = TagBuilder.create()
        .id(Tag.DEFAULT_ID)               // mandory (NOT NULL)
        .title("title")                   // mandory (NOT NULL && NOT EMPTY)
        .generationTime(Long.MIN_VALUE)   // mandory (NOT NULL)
        .description("description")       // optional
        .style("style")                   // optional
        .build();

The same as a Business process modeling (BPM) diagram (create with the tool Bizagi Modeler BPMN):

Hint
. The generation from a Tag starts with the method create().
. Green rectangles are mandory attributes.
. Blue rectangles are optional attributes.
. The Tag will then created with the last method build().

Usage of the class TagContainerIdBuilder

To identify the container and the assoziated Tags from the container a unique id is required. Here comes the following fluent builder in the game:

/**
 * With the fluent builder {@code Class} {@link com.github.naoghuman.lib.tag.core.TagContainerIdBuilder} 
 * the developer can create easily an unique {@code Id} and returned it as a {@link java.lang.String}.
 * <p>
 * The main point from this {@code builder} is the possibility to generate an unique {@code Id} for a relation 
 * between a {@link com.github.naoghuman.lib.tag.core.Tag} and the container where the {@code Tag} will be embbeded.
 * 
 * <ul>
 * <li>All attributes are {@code mandory}.</li>
 * <li>All defined values will be validate against the {@code Interface} {@link com.github.naoghuman.lib.tag.internal.DefaultTagValidator}.</li>
 * </ul>

 */
final String tagContainerId = TagContainerIdBuilder.create()
        .path(TagContainerId.class)         // mandory (NOT NULL)
        .container(AnchorPane.class)        // mandory (NOT NULL)
        .containerId("container-id")        // mandory (NOT NULL && NOT EMPTY)
        .build();

Again the same as a Business process modeling (BPM) diagram:

Usage of the class TagRelationBuilder

With a TagRelation its possible to map a Tag with a specific gui component. So the application knows which Tags should be shown for example in a Button or in a FlowPane.

/**
 * With the fluent builder {@code Class} {@link com.github.naoghuman.lib.tag.core.TagRelationBuilder} 
 * the developer can create easily an instance from the {@code Interface} 
 * {@link com.github.naoghuman.lib.tag.core.TagRelation}.
 * <ul>
 * <li>All attributes are {@code mandory}.</li>
 * <li>All defined values will be validate against the {@code Interface} {@link com.github.naoghuman.lib.tag.internal.DefaultTagValidator}.</li>
 * </ul>

 */
final TagRelation tagRelation = TagRelationBuilder.create()
        .id(TagRelation.DEFAULT_ID)                         // mandory (NOT NULL)
        .tagId(0L)                                          // mandory (NOT NULL)
        .containerId(TagContainerIdBuilder.create()
                .path(TagContainerId.class)                 // mandory (NOT NULL)
                .container(AnchorPane.class)                // mandory (NOT NULL)
                .containerId("container-id")                // mandory (NOT NULL && NOT EMPTY)
                .build())
        .build();
