Method Detail

getExtensions

public Set<String> getExtensions()

Description copied from interface: CommandManager

Returns the set of extensions managed by this implementation.

Specified by:

getExtensions in interface CommandManager

Returns:

the set of extensions, for instance ("groovy")

isActive

public boolean isActive()

Description copied from interface: CommandManager

Return true if this command manager is active. Implementation can decide based on the runtime, for instance the Groovy REPL can be inactive when Groovy is not available at runtime.

Specified by:

isActive in interface CommandManager

Returns:

the active status

doCallBack

public String doCallBack(HashMap<String,Object> session,
                         String name,
                         String defaultValue)

Specified by:

doCallBack in interface CommandManager

init

public void init(HashMap<String,Object> session)

Specified by:

init in interface CommandManager

destroy

public void destroy(HashMap<String,Object> session)

Specified by:

destroy in interface CommandManager

getGroovyShell

public static groovy.lang.GroovyShell getGroovyShell(CRaSHSession session)

The underlying groovu shell used for the REPL.

Returns:

a groovy shell operating on the session attributes

eval

private String eval(HashMap<String,Object> session,
                    String name,
                    String def)

getLifeCycle

public GroovyScript getLifeCycle(HashMap<String,Object> session,
                                 String name)
                          throws CommandCreationException,
                                 NullPointerException

Throws:

CommandCreationException

NullPointerException

resolveCommand

public CommandResolution resolveCommand(String name,
                                        byte[] source)
                                 throws CommandCreationException,
                                        NullPointerException

Description copied from interface: CommandManager

Resolve a command for the specified command name.

Specified by:

resolveCommand in interface CommandManager

Parameters:

name - the command name

source - the command source @return the command or null if no command can be resolved

Throws:

CommandCreationException - when the command exists but cannot be created

NullPointerException - if the command name is null

make

private <C extends BaseCommand> ShellCommandImpl<C> make(Class<C> clazz)

make2

private <C extends GroovyScriptCommand> GroovyScriptShellCommand<C> make2(Class<C> clazz)
