SymbolicBayesNet (SymbolicConditional &&c) | |
Construct from a single conditional. | |
SymbolicBayesNet & | operator() (SymbolicConditional &&c) |
Add a single conditional and return a reference. This allows for chaining, e.g., SymbolicBayesNet bn = SymbolicBayesNet(SymbolicConditional(...))(SymbolicConditional(...));. | |

A SymbolicBayesNet is a Bayes Net of purely symbolic conditionals.
|
inline |
Construct empty factor graph
|
inline |
Construct from iterator over conditionals
|
inlineexplicit |
Construct from container of factors (shared_ptr or plain objects)
|
inlineexplicit |
Implicit copy/downcast constructor to override explicit template container constructor
|
inline |
Constructor that takes an initializer list of shared pointers. SymbolicBayesNet bn = {make_shared<SymbolicConditional>(), ...};
|
inlineinherited |
Add a factor or container of factors, including STL collections, BayesTrees, etc.
|
inherited |
Add new factors to a factor graph and returns a list of new factor indices, optionally finding and reusing empty factor slots.
|
inlineinherited |
Get a specific factor by index (this checks array bounds and may throw an exception, as opposed to operator[] which does not).
|
inlineinherited |
Get a specific factor by index (this checks array bounds and may throw an exception, as opposed to operator[] which does not).
|
inlineinherited |
Get the last factor
|
inlineinherited |
Iterator to beginning of factors.
|
inlineinherited |
non-const STL-style begin()
|
inlineinherited |
Check if the graph is empty (null factors set by remove() will cause this to return false).
|
inlineinherited |
Iterator to end of factors.
|
inlineinherited |
non-const STL-style end()
GTSAM_EXPORT bool gtsam::SymbolicBayesNet::equals | ( | const This & | bn, |
double | tol = 1e-9 |
||
) | const |
Check equality
|
inlineinherited |
Erase factor and rearrange other factors to take up the empty space
|
inlineinherited |
Erase factors and rearrange other factors to take up the empty space
|
inherited |
Add error for all factors.
|
inlineinherited |
MATLAB interface utility: Checks whether a factor index idx exists in the graph and is a live pointer
|
inlineinherited |
Get the first factor
|
inherited |
Potentially slow function to return all keys involved, sorted, as a set
|
inherited |
Potentially slow function to return all keys involved, sorted, as a vector
|
inherited |
return the number of non-null factors
|
inlineinherited |
Get a specific factor by index (this does not check array bounds, as opposed to at() which does).
|
inlineinherited |
Get a specific factor by index (this does not check array bounds, as opposed to at() which does).
|
inlineinherited |
Add a factor by value, will be copy-constructed (use push_back with a shared_ptr to avoid the copy).
|
inlineinherited |
Push back many factors with an iterator over shared_ptr (factors are not copied)
|
inlineinherited |
Push back many factors as shared_ptr's in a container (factors are not copied)
|
inlineinherited |
Push back a BayesTree as a collection of factors. NOTE: This should be hidden in derived classes in favor of a type-specialized version that calls this templated function.
|
inlineinherited |
delete factor without re-arranging indexes by inserting a nullptr pointer
|
inlineinherited |
replace a factor by index
|
inlineinherited |
Reserve space for the specified number of factors if you know in advance how many there will be (works like FastVector::reserve).
|
inlinevirtualinherited |
Directly resize the number of factors in the graph. If the new size is less than the original, factors at the end will be removed. If the new size is larger than the original, null factors will be appended.
|
inlineinherited |
return the number of factors (including any null factors set by remove() ).

concept check, makes sure FACTOR defines print and equals Collection of factors
