Method: Cosmos::Structure#write_item

Defined in:
lib/cosmos/packets/structure.rb

#write_item(item, value, value_type = :RAW, buffer = @buffer) ⇒ Object

Write a value to the buffer based on the item definition

Parameters:

  • item (StructureItem) —

    Instance of StructureItem or one of its subclasses

  • value (Object) —

    Value based on the item definition. This could be a string, integer, float, or array of values.

  • value_type (Symbol) (defaults to: :RAW) —

    Not used. Subclasses should overload this parameter to check whether to perform conversions on the item.

  • buffer (String) (defaults to: @buffer) —

    The binary buffer to write the value to
