Method Detail

convertVarNum

public java.lang.String convertVarNum(int varNum)

Converts a number in to a string for the variable name. The format is 000var (the number is given leading 0's till it is 3 digits long). This conversion is done to help order variables when saved. This is not the same as the question number as there are hidden variables in the survey.

Parameters:

varNum - the number of the variable.

Returns:

String nV. The converted variable number.

toBoolean

public boolean toBoolean(int tf)

Converts integer codes used to store in strings and files by SurveyBuildR back to their boolean counter parts. A 0 - true and a 1 = false.

Parameters:

tf - The boolean code.

Returns:

boolean. The boolean form.

fromBoolean

public int fromBoolean(boolean tf)

Converts from a boolean to the integer codes used to store in text variables and files in SurveyBuildR. A 0 - true and a 1 = false.

Parameters:

tf - the boolean variable to be coded.

Returns:

int. The integer code.
