| /** |
| * Defines the Service Provider Interface for pluggable JShell execution engines. |
| * The JShell core tracks and compiles Snippets then sends them |
| * (represented in a wrapper class) to the execution engine for loading, |
| * and in the case of executable Snippets, execution. The JShell |
| * implementation includes a default execution engine (currently a remote |
| * process which is JDI controlled). By implementing the |
| * {@link jdk.jshell.spi.ExecutionControl} interface and its generating class, |
| * an implementation of the {@link jdk.jshell.spi.ExecutionControlProvider} |
| * interface, and installing it with |
| * {@link jdk.jshell.JShell.Builder#executionEngine(String)} |
| * other execution engines can be used. Where the passed String is an |
| * {@code ExecutionControl} spec. |
| * <p> |
| * The {@code ExecutionControl} spec is the {@code ExecutionControlProvider} |
| * name optionally followed by a parameter specification. |
| * The syntax of the spec is: |
| * <pre> |
| * spec := name : params |
| * | name |
| * name := identifier |
| * params := param , params |
| * | param |
| * | |
| * param := identifier ( value ) |
| * </pre> |
| * Where 'name' is the {@code ExecutionControlProvider} |
| * {@linkplain ExecutionControlProvider#name() name}. |
| * Where 'param' is a Map key from |
| * {@link ExecutionControlProvider#defaultParameters()} and the parenthesized |
| * value; See, for example, |
| * {@link jdk.jshell.execution.JdiExecutionControlProvider}. |
| * Where 'identifier' is a sequence of |
| * {@linkplain java.lang.Character#isJavaIdentifierPart(char) |
| * Java identifier part characters} from the Basic Multilingual Plane. |
| * <p> |
| * For example: |
| * <ul> |
| * <li>local</li> |
| * <li>jdi:hostname(localhost)</li> |
| * <li>failover:1(jdi),2(jdi:launch(true),timeout(3000)),3(local)</li> |
| * </ul> |
| * |
| * @since 9 |
| * @see jdk.jshell.execution for execution implementation support |
