Method Details

handleCommand

public Object handleCommand(Object slot,
 String address,
 String command)

Callback method of this command handler.

Specified by:

handleCommand in interface RexxCommandHandler

Parameters:

slot - opaque argument (needs to be used if invoking the Handler default methods to interact with the Rexx context)

address - the environment name this handler works for

command - the command to process

Returns:

any value, which can be retrieved on the Rexx side via the variable RC (result code)

getNonBlankWords

public static String[] getNonBlankWords(String s,
 ArrayList<int[]> al)

This will create a word array from the supplied ArrayList returned by getWordBoundaries.

Parameters:

s - String

al - ArrayList returned by getWordBoundaries

Returns:

array of words

getWordBoundaries

public static ArrayList<int[]> getWordBoundaries(String s,
 int maxNumberOfWords)

Parses the string and returns an ArrayList of int[] denoting the start and the end of each word in the string delimited by ' ' or '\t' the Rexx whitespace characters.

Parameters:

s - the string to parse

maxNumberOfWords - if -1 processes always entire string, otherwise stops after having created maxNumberOfWords items

Returns:

an ArrayList of int[] arrays

checkBooleanValue

public static boolean checkBooleanValue(String value)

Allow "1", ".true", "true" in any case to resolve to a boolean true; allow "0", ".false", "false" in any case to resolve to a boolean false;

Parameters:

value - the string that represents a BSF4ooRexx850 boolean value

Returns:

true if string represents true, false else

getBooleanValue

public static boolean getBooleanValue(String value)

Determines the boolean value of a BSF4ooRexx850 boolean string and returns it.

Parameters:

value - the string containing a BSF4ooRexx850 boolean rendering

Returns:

true if "1", ".TRUE", "TRUE" and false else
