Details
Storage.Slot.address
readonly string address
Description
The slot's address.
If the slot's storage object has an Address Scheme, the slot's address is formatted according to that address scheme. Otherwise, the address will be formatted as follows: <StorageObjectName>-<BayNumber>-<LevelNumber>-<SlotNumber>.
Storage.Slot.aisleID
readonly Variant aisleID
Description
The slot's aisle ID.
If the slot's storage object has an Address Scheme, the slot's aisle ID is formatted according to that address scheme. In other words, if the address scheme's aisles are addressed with a number, the aisle ID will be a number. Otherwise, the aisle ID will be a string. If there is no address scheme, the aisle ID will be blank. All slots in a given Storage Object use the Storage Object's aisle ID as their aisle ID.
Storage.Slot.bay
readonly Storage.Bay bay
Description
The slot's bay.
Returns the bay that this slot belongs to.
Storage.Slot.bayID
readonly Variant bayID
Description
The slot's bay ID.
If the slot's storage object has an Address Scheme, the slot's bay ID is formatted according to that address scheme. In other words, if the address scheme's bays are addressed with a letter, bayID will be a string, otherwise bayID will be a number. If there is no address scheme, bayID will be the bay number.
Bay IDs are mapped according to the storage object's Start Bay and Bay Stride.
Storage.Slot.isStorable
readonly int isStorable
Description
1 if the slot is a storable slot, 0 otherwise.
Storage.Slot.labelProperties
Variant labelProperties
Description
Use your own named properties to get/set slot label values.
The Storage.Slot class allows you to get and set custom named properties that will apply to labels on the slot. For example, if you want to set a label named "SKU" on a given slot to a value of 5, you can write the following code:
slot.SKU = 5;This will set the label's value to 5. If a label of that name does not exist, then it will be added to the slot's labels.
If you want to return the value stored in the slot's "SKU" label, you can execute the following code:
return slot.SKU;For slot labels, you MUST access the label through this dynamic properties syntax. You should not use syntax that accesses label nodes directly in the tree (like
slot.labels.assert("SKU").value = 5;). The storage
system may manage an index of slot label values for quick lookup. This index is only updated properly when you use the
dynamic property syntax to set label values.
For more information, see treenode.labelProperties.
Storage.Slot.level
readonly Storage.Level level
Description
The slot's level.
Returns the level that this slot belongs to.
Storage.Slot.levelID
readonly Variant levelID
Description
The slot's level ID.
If the slot's storage object has an Address Scheme, the slot's level ID is formatted according to that address scheme. In other words, if the address scheme's levels are addressed with a letter, levelID will be a string, otherwise levelID will be a number. If there is no address scheme, levelID will be the level number.
Level IDs are mapped according to the storage object's Start Level and Level Stride.
Storage.Slot.location
readonly Vec3 location
Description
The location of the bottom front left corner of the slot, in the local coordinates of its storage object.
Storage.Slot.slotID
readonly Variant slotID
Description
The slot's slot ID.
If the slot's storage object has an Address Scheme, the slot's slot ID is formatted according to that address scheme. In other words, if the address scheme's slots are addressed with a letter, slotID will be a string, otherwise slotID will be a number. If there is no address scheme, slotID will be the slot number.
Slot IDs are mapped according to the storage object's Start Slot and Slot Stride.
Storage.Slot.slotItems
readonly slotItems
Description
Accesses the array of Storage.Slot.Items that are stored in or assigned to this slot.
Accessing the Number of Slot Items
You can access the number of slot items with the following code.
slot.slotItems.lengthAccessing Slot Items by Rank
You can access an individual slot item by rank with the following code.
slot.slotItems[1] // first slot item
slot.slotItems[slot.slotItems.length] // last slot item
slot.slotItems[i] // i-th slot itemStorage.Slot.storageObject
readonly Storage.Object storageObject
Description
The slot's storage object.
Returns the storage object that this slot belongs to.
Storage.Slot.zoneID
readonly Variant zoneID
Description
The slot's zone ID.
If the slot's storage object has an Address Scheme, the slot's zone ID is formatted according to that address scheme. In other words, if the address scheme's zones are addressed with a number, the zone ID will be a number. Otherwise, the zone ID will be a string. If there is no address scheme, the zone ID will be blank. All slots in a given Storage Object use the Storage Object's zone ID as their zone ID.
Storage.Slot.getLocation()
| Vec3 getLocation( double xFactor , double yFactor , double zFactor ) |
| Vec3 getLocation( Vec3 factors ) |
Parameters
| xFactor | The normalized target x location within the slot. Should be in the range 0-1. |
| yFactor | The normalized target y location within the slot. Should be in the range 0-1. |
| zFactor | The normalized target z location within the slot. Should be in the range 0-1. |
| factors | Encapsulates the x, y, and z factors into a single Vec3. |
Description
Gets a location within the slot.
This method is similar to Object.getLocation(). It returns a slot-relative location, in the storage object's local coordinates.
Storage.Slot.hasSpace()
| int hasSpace( treenode item ) |
Parameters
| item | The flow item that you want place into the slot. |
Returns
| int | 1 if the slot calculates that there is enough space in the slot to place the item, 0 otherwise. |
Description
Returns 1 if it calculates that there is enough space to place the passed item into the slot, 0 otherwise.
The hasSpace() method uses the storage object's Slot Stacking Order property to "simulate" placing the item into the slot, taking into account the set of items that are already stored in or assigned to the slot. Once it has resolved where the item would be placed if it were to be stored in the slot, it checks if that placement is fully within the boundaries of the slot. If the placement is within the slot boundaries, the method will return 1, otherwise the method will return 0.
Item Size and Rotation
The item's current size and rotation are used in calculating the item's placement. The item's size and rotation are assumed to be the same as they will be when the item is eventually placed into the slot. This is important, especially for rotation, which often changes during the model run. If, when the item is finally placed into the slot, the item's rotation is different than when hasSpace() was called, then hasSpace()'s return value will have potentially been incorrect. To fix this, you should first set the rotation of the item to the rotation it will be in when it is placed in the rack, then call hasSpace(). You can then set its rotation back to whatever the item's current context requires.
Assigned-Only Items
When "simulating" the placement of the item to determine space availability, the slot will take into account not only the items that are already stored in the slot, but also the items that are assigned to the slot, but have not yet been stored in the slot. The slot will first virtually "place" the assigned-only items into the slot, in the order in which they were assigned to the slot. Then it will virtually place the currently querying item into the slot as if it entered the slot after all the other assigned items.
Because of the virtual placement of assigned-only items, it is important to note that the hasSpace() method is only a heuristic. The result of hasSpace() assumes that the order in which assigned items will be placed into the slot is the same order as their assignment to the slot, and that the item's rotation and size are the same as when it will be placed in the rack. If these factors change, or if different-sized items are placed into the slot in a different order than their assignment order, then hasSpace() will have returned a value inconsistent with the actually reality of whether there is space in the slot after all assigned items have been placed.
Storage.Slot.restack()
| void restack( int fromRank = 0 ) |
Parameters
| fromRank | If non-zero, the slot will only start at the item at the defined rack, and restack from that point. |
Description
Performs again the slot stacking algorithm on some or all items stored in the slot.
For storage objects whose Slot Stacking Order only stacks along a single axis (and for Gravity Flow and Push Back Racks) the storage object will automatically restack when an item is picked from a position that would require a restack. For slot stacking orders that include multiple axes, however, the storage object does not automatically restack the slot when items are picked from a middle or front position. As such, you can manually restack the slot using this method.
