Public Member Functions | |
Owner constructors | |
These constructors create a Vector_ object that allocates new data on the heap and serves as the owner of that data. Any existing data that is supplied in these constructors is copied, not shared. | |
Vector_ () | |
Default constructor creates a 0x1, reallocatable vector. More... | |
Vector_ (const Vector_ &src) | |
Copy constructor is deep, that is the source Vector_ is copied, not referenced. More... | |
Vector_ (const Base &src) | |
This copy constructor serves as an implicit conversion from objects of the base class type (for example, a VectorView_<ELT>), to objects of this Vector_<ELT> type. More... | |
Vector_ (const BaseNeg &src) | |
This copy constructor serves as an implicit conversion from objects of the base class but with negated elements, to objects of this Vector_<ELT> type. More... | |
Vector_ (int m) | |
Construct a Vector_ with a given preallocated size, but with uninitialized values. More... | |
Vector_ (int m, const ELT *cppInitialValues) | |
Construct an owner Vector_ of a given size m and initialize it from a C++ array of m ELT values pointed to by cppInitialValues. More... | |

Construct an owner Vector_ of a given size m and initialize all the elements to the given ELT value initialValue. More... | |
template<int M> | |
Vector_ (const Vec< M, ELT > &v) | |
This constructor creates a new owner Vector_ that is the same length and has a copy of the contents of a given fixed-size Vec. More... | |
View constructors | |
These constructors create a Vector_ object that is a view of existing data that is owned by some other object. Any existing data that is supplied in these constructors is shared, not copied, so writing to the created Vector_ view modifies the original data. | |
Vector_ (int m, const S *cppData, bool) | |
Construct a Vector_ which shares read-only, borrowed space with assumed element-to-element stride equal to the C++ element spacing. More... | |

These methods are at namespace scope but are logically part of the Vector classes. These deal with reading and writing Vectors from and to streams, which places an additional requirement on the element type T: the element must support the same operation you are trying to do on the Vector as a whole. | |

This is the vector class intended to appear in user code for large, variable size column vectors.
More commonly, the typedef Vector is used instead; that is just an abbreviation for Vector_<Real>
.
A Vector_ can be a fixed-size view of someone else's data, or can be a resizable data owner itself, although of course it will always have just one column.

inline |
Default constructor creates a 0x1, reallocatable vector.
|
inline |
Copy constructor is deep, that is the source Vector_ is copied, not referenced.
|
inline |
This copy constructor serves as an implicit conversion from objects of the base class type (for example, a VectorView_<ELT>), to objects of this Vector_<ELT> type.
Note that the source object is copied, not referenced.

inlineexplicit |
Construct a Vector_ with a given preallocated size, but with uninitialized values.
In Debug builds the elements will be initialized to NaN as a debugging aid, but in Release (optimized) builds they will be uninitialized garbage so that we don't waste time setting them.
|
inline |
Construct an owner Vector_ of a given size m and initialize it from a C++ array of m ELT values pointed to by cppInitialValues.
Note that there is no way to check that the correct number of elements has been provided; make sure you have supplied enough of them.
|
inline |
Construct an owner Vector_ of a given size m and initialize all the elements to the given ELT value initialValue.
|
inlineexplicit |
This constructor creates a new owner Vector_ that is the same length and has a copy of the contents of a given fixed-size Vec.

Construct a Vector_ which shares read-only, borrowed space with assumed element-to-element stride equal to the C++ element spacing.
Last parameter is a required dummy to avoid overload conflicts when ELT=S; pass it as "true".

Copy assignment is deep and can be reallocating if this Vector_ is an owner.
Otherwise the source is copied into the destination view.
|
inline |
Like copy assignment but the source can be any object of the base type, even with a different element type EE as long as that element type is assignment-compatible to an element of our type ELT.
|
inline |
Set all elements of this Vector_ to the same value v.
|
inline |
Add in a conforming vector of the base type even if it has a different element type EE, provided that element type is add-compatible with our element type ELT, meaning that ELT+=EE is allowed.

inline |
In-place subtract of a conforming vector of the base type even if it has a different element type EE, provided that element type is subtract-compatible with our element type ELT, meaning that ELT-=EE is allowed.

inline |
In-place multiply of each element of this Vector_ by a scalar t.
Returns a reference to the now-modified Vector_.

inline |
In-place divide of each element of this Vector_ by a scalar t.
Returns a reference to the now-modified Vector_.
|
inline |
In-place add to each element of this Vector_ the same given value b.
Returns a reference to the now-modified Vector_. This is the same operation as elementwiseAddScalarInPlace().
|
inline |
In-place subtract from each element of this Vector_ the same given value b.
Returns a reference to the now-modified Vector_. This is the same operation as elementwiseSubtractScalarInPlace().

Output a human readable representation of a Vector to an std::ostream (like std::cout).
The format is ~[ elements ] where elements is a space-separated list of the Vector's contents output by invoking the "<<" operator on the elements. This function will not compile if the element type does not support the "<<" operator. No newline is issued before or after the output.

Read in a Vector_<T> from a stream, as a sequence of space-separated or comma-separated values optionally surrounded by parentheses (), or square brackets [], or the "transposed" ~() or ~[].
In the case that the transpose operator is present, the parentheses or brackets are required, otherwise they are optional. We will continue to read elements of type T from the stream until we find a reason to stop, using type T's stream extraction operator>>() to read in each element and resizing the Vector as necessary. If the data is bracketed, we'll read until we hit the closing bracket. If it is not bracketed, we'll read until we hit eof() or get an error such as the element extractor setting the stream's fail bit due to bad formatting. On successful return, the stream will be positioned right after the final read-in element or terminating bracket, and the stream's status will be good() or eof(). We will not consume trailing whitespace after bracketed elements; that means the stream might actually be empty even if we don't return eof(). If you want to know whether there is anything else in the stream, follow this call with the STL whitespace skipper std::ws() like this:
A compilation error will occur if you try to use this method on an Vector_<T> for a type T for which there is no stream extraction operator>>().

Read in a fixed number of elements from a stream into a Vector.
We expect to read in exactly size() elements of type T, using type T's stream extraction operator>>(). This will stop reading when we've read size() elements, or set the fail bit in the stream if we run out of elements or if any element's extract operator sets the fail bit. On successful return, all size() elements will have been set, the stream will be positioned right after the final read-in element or terminating bracket, and the stream's status will be good() or eof(). We will not consume trailing whitespace after reading all the elements; that means the stream might actually be empty even if we don't return eof(). If you want to know whether there is anything else in the stream, follow this call with std::ws() like this:
A compilation error will occur if you try to use this method on a Vector_<T> for a type T for which there is no stream extraction operator>>().
Read Vector_<T> from a stream as a sequence of space- or comma-separated values of type T, optionally delimited by parentheses, or brackets, and preceded by "~".
The Vector_<T> may be an owner (variable size) or a view (fixed size n). In the case of an owner, we'll read all the elements in brackets or until eof if there are no brackets. In the case of a view, there must be exactly n elements in brackets, or if there are no brackets we'll consume exactly n elements and then stop. Each element is read in with its own operator ">>" so this won't work if no such operator is defined for type T.
