In query mode, return type is based on queried flag.

Flags

Long name (short name)	Argument types	Properties
-name(-n)	string
Used to specify the name of the node being created
-geometry(-g)	string
The specified object will be added to the list of objects being deformed by this deformer object, unless the -rm flag is also specified. When queried, this flag returns string string string ...
-remove(-rm)
Specifies that objects listed after the -g flag should be removed from this deformer.
-before(-bf)
If the default behavior for insertion/appending into/onto the existing chain is not what you want then you can use this flag to force the command to stick the deformer node before the selected node in the chain even if a new geometry shape has to be created in order to do so
-after(-af)
If the default behavior for insertion/appending into/onto the existing chain is not what you want then you can use this flag to force the command to stick the deformer node after the selected node in the chain even if a new geometry shape has to be created in order to do so
-split(-sp)
Branches off a new chain in the dependency graph instead of inserting/appending the deformer into/onto an existing chain.
-frontOfChain(-foc)
This command is used to specify that the new deformer node should be placed ahead (upstream) of existing deformer and skin nodes in the shape's history (but not ahead of existing tweak nodes). The input to the deformer will be the upstream shape rather than the visible downstream shape, so the behavior of this flag is the most intuitive if the downstream deformers are in their reset (hasNoEffect) position when the new deformer is added.
-parallel(-par)
Inserts the new deformer in a parallel chain to any existing deformers in the history of the object. A blendShape is inserted to blend the parallel results together.
-ignoreSelected(-is)
Tells the command to not deform objects on the current selection list
-deformerTools(-dt)
Returns the name of the deformer tool objects (if any) as string string ...
-prune(-pr)
Removes any points not being deformed by the deformer in its current configuration from the deformer set.
-exclusive(-ex)	string
Puts the deformation set in a deform partition.
-divisions(-dv)	uint uint uint
Set the number of lattice slices in x, y, z. Default is 2, 5, 2. When queried, this flag returns float float float. When you change the number of divisions, any tweaking or animation of lattice points must be redone.
-ldivisions(-ldv)	uint uint uint
Set the number of local lattice slices in x, y, z.
-objectCentered(-oc)	boolean
Centers the lattice around the selected object(s) or components. Default is off which centers the lattice at the origin.
-outsideLattice(-ol)	uint
Set the mode describing how points outside the base lattice are transformed. 0 (the default) specifies that no outside points are transformed. 1 specifies that all outside points are transformed, and 2 specifies that only those outside points which fall within the "falloff distance" (see the -ofd/outsideFalloffDistance flag) are transformed. When querying, the current setting for the lattice is returned.
-outsideFalloffDistance(-ofd)	float
Set the falloff distance used when the setting for transforming points outside of the base lattice is set to 2. The distance value is a positive number which specifies the size of the falloff distance as a multiple of the base lattice size, thus a value of 1.0 specifies that only points up to the base lattice width/height/depth away are transformed. A value of 0.0 is equivalent to an outsideLattice value of 0 (i.e. no points outside the base lattice are transformed). A huge value is equivalent to transforming an outsideLattice value of 1 (i.e. all points are transformed).
-latticeReset(-lr)
Reset the lattice to match its base position. This will undo any deformations that the lattice is causing. The lattice will only deform points that are enclosed within the lattice's reset (base) position.
-removeTweaks(-rt)
Remove any lattice deformations caused by moving lattice points. Translations/rotations and scales on the lattice itself are not removed.
-freezeMapping(-fm)	boolean
The base position of the geometries points is fixed at the time this flag is set. When mapping is frozen, moving the geometry with respect to the lattice will not cause the deformation to be recomputed.
-commonParent(-cp)
Group the base lattice and the deformed lattice under a common transform. This means that you can resize the lattice without affecting the deformation by resizing the common transform.
-position(-pos)	linear linear linear
Used to specify the position of the newly created lattice.
-rotation(-ro)	angle angle angle
Used to specify the initial rotation of the newly created lattice.
-scale(-s)	linear linear linear
Used to specify the initial scale of the newly created lattice.
-dualBase(-db)	boolean
Create a special purpose ffd deformer node which accepts 2 base lattices. The default is off which results in the creation of a normal ffd deformer node. Intended for internal usage only.
