Module jdk.jshell
The jdk.jshell
is the package for creating 'snippet' evaluating tools. Generally, this is only package that would be needed for creating tools.
The jdk.jshell.spi
package specifies a Service Provider Interface (SPI) for defining execution engine implementations for tools based on the jdk.jshell
API. The jdk.jshell.execution
package provides standard implementations of jdk.jshell.spi
interfaces and supporting code. It also serves as a library of functionality for defining new execution engine implementations.
The jdk.jshell.tool
package supports programmatically launching the jshell tool.
The jdk.jshell.execution
package contains implementations of the interfaces in jdk.jshell.spi
. Otherwise, the four packages are independent, operate at different levels, and do not share functionality or definitions.
