Constructor Detail

IOEvaluator

public IOEvaluator()

Method Detail

getNamespace

public String getNamespace()

getFunctionNames

public String[] getFunctionNames()

Specified by:

getFunctionNames in class AbstractEvaluator

getType

public int getType(String name)

dispatch

public boolean dispatch(Polyad polyad,
                        State state)

Description copied from class: AbstractEvaluator

Does the actual evaluation of the Polyad.

Specified by:

dispatch in class AbstractEvaluator

Returns:

doScan

protected void doScan(Polyad polyad,
                      State state)

doRMDir

protected void doRMDir(Polyad polyad,
                       State state)

doRMFile

protected void doRMFile(Polyad polyad,
                        State state)

doMkDir

protected void doMkDir(Polyad polyad,
                       State state)

doDir

protected void doDir(Polyad polyad,
                     State state)

Quick note. This is a directory command. That means that it will list the things in a directory. This is not like, e.g., the unix ls command. The ls command lists information so

ls filename

returns the file name. This command returns what is in the directory. So dir(filename) returns null since the name is not a directory.

Parameters:

polyad -

state -

vfsUnmount

protected void vfsUnmount(Polyad polyad,
                          State state)

vfsMount

protected void vfsMount(Polyad polyad,
                        State state)

doWriteFile

protected void doWriteFile(Polyad polyad,
                           State state)

processWriteFileStem

protected QDLStem processWriteFileStem(QDLStem input,
                                       State state,
                                       Polyad polyad)

writeSingleFile

protected void writeSingleFile(String fileName,
                               QDLValue content,
                               int fileType,
                               State state,
