BCommand ( )

BCommand ( const SContext & context )

~BCommand ( ) [protected, virtual]

Member Function Documentation

FILE * __sF ( int which ) const

void AddCommand ( const SString & name,

const sptr< ICommand > & command

) [virtual]

Implements ICommand.

sptr< IBinder > ArgToBinder ( const SValue & arg ) const

Given an argument value, convert it to an object.
If the SValue contains an object, the binder is returned directly. Otherwise, if it is a string, this is taken as a path and looked up in the context.

SString ArgToPath ( const SValue & arg ) const

Given an argument value, convert it to an absolute path.
If the SValue contains a string, it is appended to the PWD and returned. Otherwise, "" is returned.

sptr< IByteOutput > ByteError ( ) const [virtual]

Implements ICommand.

sptr< IByteInput > ByteInput ( ) const [virtual]

Implements ICommand.

sptr< IByteOutput > ByteOutput ( ) const [virtual]

Implements ICommand.

sptr< ICommand > Clone ( ) const [virtual]

SString CurDir ( ) const

int32_t CurrentPropertySequence ( ) const

SString Documentation ( ) const [virtual]

Retrieve a short description of the command.
(Here's one we stole from Python.) Every command may optionally have a documentation property. This can be retrieved at runtime to provide detailed help on any command. Shell users everywhere rejoice!
Implements ICommand.

SValue Environment ( ) const [virtual]

Implements ICommand.

bool GetColorFlag ( ) const

sptr< ICommand > GetCommand ( const SString & name ) const [virtual]

Implements ICommand.

bool GetEchoFlag ( ) const

const char * getenv ( const char * key ) const

SValue GetProperty ( const SValue & key ) const [virtual]

Implements ICommand.

bool GetTraceFlag ( ) const

int putenv ( const char * string )

void RemoveCommand ( const SString & name ) [virtual]

Implements ICommand.

void RemoveProperty ( const SValue & key ) [virtual]

Implements ICommand.

virtual SValue Run ( const ArgList & args ) [pure virtual]

Implemented in BUnixCommand.

void SetByteError ( const sptr< IByteOutput > & error ) [virtual]

Implements ICommand.

void SetByteInput ( const sptr< IByteInput > & input ) [virtual]

Implements ICommand.

void SetByteOutput ( const sptr< IByteOutput > & output ) [virtual]

Implements ICommand.

int setenv ( const char * name,

const char * value,

int rewrite

)

void SetEnvironment ( const SValue & env ) [virtual]

const SValue & value

) [virtual]

Implements ICommand.

sptr< ICommand > Spawn ( const SString & command ) const [virtual]

Implements ICommand.

sptr< ICommand > SpawnCustom ( const SString & command,

const SContext & context,

const sptr< IProcess > & team

) const

int system ( const char * cmd )

sptr< ITextOutput > TextError ( )
