Class cornell.slk.jkernel.std.StartData 

java.lang.Object
    |
    +----cornell.slk.jkernel.std.StartData
public class StartData
extends java.lang.Object
implements FastCopyTree
StartData contains a number of resources that the first user task can use. These are particularly useful when launching other tasks. Be warned that some of these fields contain dangerous objects that should be guarded closely.

All of the resolvers and streams in StartData are capabilities, so that they can be passed around to other tasks.

Field Summary
Resolver  allSystemClasses
All the system classes installed in the system.
java.lang.String[]  args
The command-line arguments passed to the user's first task
Resolver  fileSystemClasses
A resolver that returns the system classes in java.io that deal with files
java.lang.String  mainClass
The name of the class used to start the user's first task
Resolver  mainResolver
The resolver that was used to load bytecode for the main class (by default, this is a FileResolver based on the system class path).
Resolver  netSystemClasses
A resolver that returns system classes in java.net
Resolver  reflectionSystemClasses
A resolver that returns system classes in java.lang.reflect
RemoteOutputStream  remoteErr
A stream connected to System.err
RemoteInputStream  remoteIn
A stream connected to System.in
RemoteOutputStream  remoteOut
A stream connected to System.out
Resolver  standardLibClasses
Several commonly used classes, including replacements for some java.lang classes, and stuff in jkernel.util
Resolver  standardResolver
A compound resolver containing both standardSystemClasses and standardLibClasses
Resolver  standardSystemClasses
The standard, "safe" system classes that may be used by anyone
Resolver  systemRuntimeDangerousClasses
A resolver that returns class SystemRuntimeDangerous, which holds all the dangerous functions in System and Runtime

remoteErr

public RemoteOutputStream remoteErr
A stream connected to System.err

remoteIn

public RemoteInputStream remoteIn
A stream connected to System.in

standardSystemClasses

public Resolver standardSystemClasses
The standard, "safe" system classes that may be used by anyone

standardLibClasses

public Resolver standardLibClasses
Several commonly used classes, including replacements for some java.lang classes, and stuff in jkernel.util

standardResolver

public Resolver standardResolver
A compound resolver containing both standardSystemClasses and standardLibClasses

mainResolver

public Resolver mainResolver
The resolver that was used to load bytecode for the main class (by default, this is a FileResolver based on the system class path).

reflectionSystemClasses

public Resolver reflectionSystemClasses
A resolver that returns system classes in java.lang.reflect

fileSystemClasses

public Resolver fileSystemClasses
A resolver that returns the system classes in java.io that deal with files

systemRuntimeDangerousClasses

public Resolver systemRuntimeDangerousClasses

netSystemClasses

public Resolver netSystemClasses

allSystemClasses

public Resolver allSystemClasses
All the system classes installed in the system. Use at your own risk. If you must use this, we recommend filtering it with a FilterResolver so that you only get the system classes that you absolutely need, and nothing more. We don't like system classes.
