public SandboxedAwkTuples()

Method Details

printToFile

public void printToFile(int numExprs,
 boolean append)

Description copied from class: AwkTuples

printToFile.

Overrides:

printToFile in class AwkTuples

Parameters:

numExprs - a int

append - a boolean

printToPipe

public void printToPipe(int numExprs)

Description copied from class: AwkTuples

printToPipe.

Overrides:

printToPipe in class AwkTuples

Parameters:

numExprs - a int

printfToFile

public void printfToFile(int numExprs,
 boolean append)

Description copied from class: AwkTuples

printfToFile.

Overrides:

printfToFile in class AwkTuples

Parameters:

numExprs - a int

append - a boolean

printfToPipe

public void printfToPipe(int numExprs)

Description copied from class: AwkTuples

printfToPipe.

Overrides:

printfToPipe in class AwkTuples

Parameters:

numExprs - a int

system

public void system()

Description copied from class: AwkTuples

system.

Overrides:

system in class AwkTuples

useAsCommandInput

public void useAsCommandInput()

Description copied from class: AwkTuples

useAsCommandInput.

Overrides:

useAsCommandInput in class AwkTuples

useAsFileInput

public void useAsFileInput()

Description copied from class: AwkTuples

useAsFileInput.

Overrides:

useAsFileInput in class AwkTuples

assignARGC

public void assignARGC()

In sandbox mode, ARGC is read-only. Block any script attempt to assign to ARGC at compile time.

Overrides:

assignARGC in class AwkTuples

argcOffset

public void argcOffset(int offset)

In sandbox mode, ARGC does not need to be materialized as a global variable because the script cannot alter it. The runtime falls back to the command-line argument count.

Overrides:

argcOffset in class AwkTuples

Parameters:

offset - a int

argvOffset

public void argvOffset(int offset)

In sandbox mode, ARGV does not need to be materialized as a global variable because the script cannot alter it. The runtime falls back to a synthetic ARGV built from command-line arguments.

Overrides:

argvOffset in class AwkTuples

Parameters:

offset - a int
