    Modifier and Type
    Method
    Description
    byte
    get(int i)
    Returns the byte value at the supplied row.
    ColumnName
    getName()
    Returns the logical column name.
    boolean
    isAllSet()
    Indicates whether every row in the column contains a value.
    boolean
    isConstant()
    Indicates whether the column represents the same value for every row.Unset values are part of the value pattern, so an all-unset column is constant, while a mix of unset and set values is not constant unless the implementation explicitly defines that pattern as constant.
    boolean
    isNoneSet()
    Indicates whether no row in the column contains a value.
    boolean
    isSet(int i)
    Indicates whether the value at the supplied row is present.
    boolean
    isXls()
    Indicates whether the byte values match the legacy XLS file signature.
    boolean
    isXlsx()
    Indicates whether the byte values match the XLSX file signature.
    int
    size()
    Returns the number of rows in the column.
    byte[]
    toArray(byte[] x)
    Copies the values into the provided array, allocating a new array when necessary.
    Column
    view(ViewIndex rowIndex)
    Returns a projected view of this column using the supplied row mapping.
