public StringTrimmerEditor(boolean emptyAsNull) { this.charsToDelete = null; this.emptyAsNull = emptyAsNull; } Create a new StringTrimmerEditor. Parameters: `emptyAsNull` - `true` if an empty String is to be transformed into `null`
public StringTrimmerEditor(String charsToDelete, boolean emptyAsNull) { this.charsToDelete = charsToDelete; this.emptyAsNull = emptyAsNull; } Create a new StringTrimmerEditor. Parameters: `charsToDelete` - a set of characters to delete, in addition to trimming an input String. Useful for deleting unwanted line breaks: e.g. "\r\n\f" will delete all new lines and line feeds in a String. `emptyAsNull` - `true` if an empty String is to be transformed into `null`
