Member Function Documentation
◆ IsInitialized()
template<class T >
|
inlinevirtual |
Determines whether this object is initialized.
- Returns
- true if this object is initialized, false otherwise
Implements DL_FixedBasePrecomputation< T >.
Definition at line 136 of file eprecomp.h.
◆ SetBase()
template<class T >
|
virtual |
Set the base element.
- Parameters
-
group the group base element in the group
Implements DL_FixedBasePrecomputation< T >.
◆ GetBase()
template<class T >
|
inlinevirtual |
Get the base element.
- Parameters
-
group the group
- Returns
- base element in the group
Implements DL_FixedBasePrecomputation< T >.
Definition at line 139 of file eprecomp.h.
◆ Precompute()
template<class T >
|
virtual |
Perform precomputation.
- Parameters
-
group the group maxExpBits used to calculate the exponent base storage the suggested number of objects for the precompute table
The exact semantics of Precompute() varies, but it typically means calculate a table of n objects that can be used later to speed up computation.
If a derived class does not override Precompute(), then the base class throws NotImplemented.

Implements DL_FixedBasePrecomputation< T >.
◆ Load()
template<class T >
|
virtual |
Retrieve previously saved precomputation.
- Parameters
-
group the group storedPrecomputation BufferedTransformation with the saved precomputation
- Exceptions
-
NotImplemented
- See also
- SupportsPrecomputation(), Precompute()
Implements DL_FixedBasePrecomputation< T >.
◆ Save()
template<class T >
|
virtual |
Save precomputation for later use.
- Parameters
-
group the group storedPrecomputation BufferedTransformation to write the precomputation
- Exceptions
-
NotImplemented
- See also
- SupportsPrecomputation(), Precompute()
Implements DL_FixedBasePrecomputation< T >.
◆ Exponentiate()
template<class T >
|
virtual |
Exponentiates an element.
- Parameters
-
group the group exponent the exponent
- Returns
- the result of the exponentiation
Implements DL_FixedBasePrecomputation< T >.
◆ CascadeExponentiate()
template<class T >
|
virtual |
Exponentiates an element.
- Parameters
-
pc1 the first the group precomputation exponent1 the first exponent pc2 the second the group precomputation exponent2 the first exponent2
- Returns
- the public element raised to the exponent
CascadeExponentiateBaseAndPublicElement raises the public element to the base element and precomputation.
