        public void ensureCapacity​(int row,
                           int column)
        Ensures that there is storage capacity for the specified item.
        Parameters:
        row - the row index.
        column - the column index.

      • getRowCount

        public int getRowCount()
        Returns the number of rows in the table.
        Returns:
        The row count.

        public int getColumnCount()
        Returns the number of columns in the table.
        Returns:
        The column count.

      • equals

        public boolean equals​(java.lang.Object o)
        Tests this paint table for equality with another object (typically also an ObjectTable).
        Overrides:
        equals in class java.lang.Object
        Parameters:
        o - the other object.
        Returns:
        A boolean.

      • hashCode

        public int hashCode()
        Returns a hash code value for the object.
        Overrides:
        hashCode in class java.lang.Object
        Returns:
        the hashcode

      • clear

        public void clear()
        Clears the table.

      • clearRow

        public void clearRow​(int row)
        Clears the row by removing the array that stores the row-data. This reduces the in-memory size of the table at the cost of possibly having to recreate the row-data-array later.
        Parameters:
        row - the row to be deleted.
