Constructor Details

#initialize(name, bit_offset, bit_size, data_type, endianness, array_size = nil, overflow = :ERROR) ⇒ TableItem

Create a StructureItem by setting all the attributes. It calls all the setter routines to do the attribute verification and then verifies the overall integrity.

It also initializes the attributes of the PacketItem.

Parameters:

  • name (String) —

    The item name

  • bit_offset (Integer) —

    Offset to the item starting at 0

  • bit_size (Integer) —

    Size of the items in bits

  • data_type (Symbol) —

    DATA_TYPES

  • endianness (Symbol) —

    BinaryAccessor::ENDIANNESS

  • array_size (Integer, nil) (defaults to: nil) —

    Size of the array item in bits. For example, if the bit_size is 8, an array_size of 16 holds two values.

  • overflow (Symbol) (defaults to: :ERROR) —

    BinaryAccessor::OVERFLOW_TYPES
