Examples with Command io.spine.core.Command used on opensource projects

Example 6 with Command

use of io.spine.core.Command in project core-java by SpineEventEngine.

the class IteratingCommandRouter method routeNext.

/**
 * Creates and posts a next command.
 *
 * <p>The commands are created and posted in the sequence their messages were added.
 *
 * @return the posted command
 * @throws NoSuchElementException if there are no command messages to post
 * @see #hasNext()
 */

Example 7 with Command

use of io.spine.core.Command in project core-java by SpineEventEngine.

the class CommandFactory method create.

/**
 * Creates a new {@code Command} with the passed message and target entity version.
 *
 * <p>The {@code targetVersion} parameter defines the version of the entity which handles
 * the resulting command. Note that the framework performs no validation of the target version
 * before a command is handled. The validation may be performed by the user themselves instead.
 *
 * @param message       the command message
 * @param targetVersion the version of the entity for which this command is intended
 * @return new command instance
 * @throws ValidationException if the passed message does not satisfy the constraints
 *                             set for it in its Protobuf definition

Example 8 with Command

use of io.spine.core.Command in project core-java by SpineEventEngine.

the class CommandFactory method createCommand.

/**
 * Creates a command instance with the given {@code message} and {@code context}.
 *
 * <p>If an instance of {@link Any} is passed as the {@code message} parameter, the packed
 * message is used for the command construction.

Example 9 with Command

use of io.spine.core.Command in project core-java by SpineEventEngine.
