        public boolean isDelimiter​(java.lang.CharSequence buffer,
                           int pos)
        Returns true if the specified character is a whitespace parameter. Check to ensure that the character is not escaped by any of getQuoteChars(), and is not escaped by any of the getEscapeChars(), and returns true from isDelimiterChar(java.lang.CharSequence, int).
        Parameters:
        buffer - The complete command buffer
        pos - The index of the character in the buffer
        Returns:
        True if the character should be a delimiter

      • isQuoted

        public boolean isQuoted​(java.lang.CharSequence buffer,
                        int pos)

      • isQuoteChar

        public boolean isQuoteChar​(java.lang.CharSequence buffer,

      • isEscapeChar

        public boolean isEscapeChar​(char ch)
        Specified by:
        isEscapeChar in interface Parser

      • isEscapeChar

        public boolean isEscapeChar​(java.lang.CharSequence buffer,
                            int pos)
        Check if this character is a valid escape char (i.e. one that has not been escaped)
        Parameters:
        buffer - the buffer to check in
        pos - the position of the character to check
        Returns:
        true if the character at the specified position in the given buffer is an escape character and the character immediately preceding it is not an escape character.

      • isEscaped

        public boolean isEscaped​(java.lang.CharSequence buffer,
                         int pos)
        Check if a character is escaped (i.e. if the previous character is an escape)
        Parameters:
        buffer - the buffer to check in
        pos - the position of the character to check
        Returns:
        true if the character at the specified position in the given buffer is an escape character and the character immediately preceding it is an escape character.

      • isDelimiterChar

        public boolean isDelimiterChar​(java.lang.CharSequence buffer,
                               int pos)
        Returns true if the character at the specified position if a delimiter. This method will only be called if the character is not enclosed in any of the getQuoteChars(), and is not escaped by any of the getEscapeChars(). To perform escaping manually, override isDelimiter(java.lang.CharSequence, int) instead.
        Parameters:
        buffer - the buffer to check in
        pos - the position of the character to check
        Returns:
        true if the character at the specified position in the given buffer is a delimiter.
