Class CommandLine.Help.TextTable

  • Enclosing class:
    CommandLine.Help
    public static class CommandLine.Help.TextTable
extends Object

    Responsible for spacing out CommandLine.Help.Ansi.Text values according to the CommandLine.Help.Column definitions the table was created with. Columns have a width, indentation, and an overflow policy that decides what to do if a value is longer than the column's width.

      • addEmptyRow

        public void addEmptyRow()
        Adds the required char[] slots for a new row to the columnValues field.

      • addRowValues

        public void addRowValues​(String... values)
        Delegates to addRowValues(CommandLine.Help.Ansi.Text...), after ensuring that multi-line values are layed out in the correct row and column.
        Parameters:
        values - the text values to display in each column of the current row

      • addRowValues

        public void addRowValues​(CommandLine.Help.Ansi.Text... values)
        Adds a new empty row, then calls putValue for each of the specified values, adding more empty rows if the return value indicates that the value spanned multiple columns or was wrapped to multiple rows.
        Parameters:
        values - the values to write into a new row in this TextTable
        Throws:
        IllegalArgumentException - if the number of values exceeds the number of Columns in this table

      • putValue

        public CommandLine.Help.TextTable.Cell putValue​(int row,

        Writes the specified value into the cell at the specified row and column and returns the last row and column written to. Depending on the Column's Overflow policy, the value may span multiple columns or wrap to multiple rows when larger than the column width.
        Parameters:
        row - the target row in the table
        col - the target column in the table to write to
        value - the value to write

        Throws:
        IllegalArgumentException - if the specified row exceeds the table's row count
        Since:

      • toString
