---An array of fluid boxes of an entity. Entities may contain more than one fluid box, and some can change the number of fluid boxes -- for instance, an assembling machine will change its number of fluid boxes depending on its active recipe. See [Fluid](https://lua-api.factorio.com/latest/Concepts.html#Fluid).
---
---Do note that reading from a [LuaFluidBox](https://lua-api.factorio.com/latest/LuaFluidBox.html) creates a new table and writing will copy the given fields from the table into the engine's own fluid box structure. Therefore, the correct way to update a fluidbox of an entity is to read it first, modify the table, then write the modified table back. Directly accessing the returned table's attributes won't have the desired effect.

---### Example  
---Double the temperature of the fluid in `entity`'s first fluid box. 
---```
---fluid = entity.fluidbox[1]
---fluid.temperature = fluid.temperature * 2
---entity.fluidbox[1] = fluid
---```
---@class LuaFluidBox:LuaObject
---[R]  
---The class name of this object. Available even when `valid` is false. For LuaStruct objects it may also be suffixed with a dotted path to a member of the struct.

---@field object_name string 
---[R]  
---The entity that owns this fluidbox.

---@field owner LuaEntity 
---[R]  
---Is this object valid? This Lua object holds a reference to an object within the game engine. It is possible that the game-engine object is removed whilst a mod still holds the corresponding Lua object. If that happens, the object becomes invalid, i.e. this attribute will be `false`. Mods are advised to check for object validity if any change to the game state might have occurred between the creation of the Lua object and its access.

---@operator len: uint
---[R]  
---Access, set or clear a fluid box. The index must always be in bounds (see [LuaFluidBox::length_operator](https://lua-api.factorio.com/latest/LuaFluidBox.html#LuaFluidBox.length_operator)). New fluidboxes may not be added or removed using this operator.
---
---Is `nil` if the given fluid box does not contain any fluid. Writing `nil` removes all fluid from the fluid box.
