Method Detail

callGC

public static void callGC()

Call the Java garbage collector. Calling this method should generally be avoided.

display

public static void display(String s)

Output a string to the Stata Results window. Before the string is printed, it is run through the Stata SMCL interpreter.

Parameters:

s - The string to output.

displayln

public static void displayln(String s)

Output a string to the Stata Results window and automatically add a line terminator at the end. Before the string is printed, it is run through the Stata SMCL interpreter.

Parameters:

s - The string to output.

error

public static void error(String s)

Output a string to the Stata Results window as an error.

Parameters:

s - The string to output.

errorDebug

public static boolean errorDebug(String s)

Output a string to the Stata Results window as an error if set debug on is enabled.

Parameters:

s - The string to output.

Returns:

Returns true if set debug on is enabled.

errorln

public static void errorln(String s)

Output a string to the Stata Results window and automatically add a line terminator at the end.

Parameters:

s - The string to output.

formatValue

public static String formatValue(double val,
                 String format)

Format a value using a Stata format.

Parameters:

val - The value to format.

format - A valid Stata format.

Returns:

The formatted value in String form. If an error occurs, a null String will be returned.

getCallerVersion

public static double getCallerVersion()

Get the version number of the calling program. This function can be used to implement Stata version control.

Returns:

Returns the caller's version number.

getTempFile

public static String getTempFile()

Get a valid Stata temporary filename.

Returns:

Returns the filename, including its path.

getTempName

public static String getTempName()

Get a valid Stata temporary name.

Returns:

Returns the tempname.

getWorkingDir

public static String getWorkingDir()

Get the current Stata working directory.

Returns:

Returns the path of the current working directory.

isValidName

public static boolean isValidName(String s)

Check if a String is a valid Stata name.

Parameters:

s - Name to test.

Returns:

Returns true if the String represents a valid Stata name.

isValidVariableName

public static boolean isValidVariableName(String s)

Check if a String is a valid Stata variable name.

Parameters:

s - Name to test.

Returns:

Returns true if the String represents a valid Stata variable name.

pollnow

public static int pollnow()

Request that Stata poll its GUI immediately. Use this method inside a time-consuming task so that the Stata interface is responsive to user inputs. Generally, pollstd should be used instead.

Returns:

Returns 0 unless the Break key has been pressed.

pollstd

public static int pollstd()

Request that Stata poll its GUI at the standard interval. Use this method inside a time-consuming task so that the Stata interface is responsive to user inputs.

Returns:

Returns 0 unless the Break key has been pressed.

stackTraceToString

public static String stackTraceToString(Exception e)

Convert the stack trace from an Exception to a String.

Parameters:

e - Exception

Returns:

String representation of the stack trace.
