Detailed Description

Namespace for LArSoft dumping utilities.

Function Documentation

template<size_t N, typename Array >

auto lar::dump::array

(

Array const &

a

)

Returns a manipulator which will print the specified array.

Template Parameters

N	the number of entries to be printed
Array	the type of array to be printed

Parameters

a	the array to be printed

Returns

a manipulator

Example of usage:

double const data[5] = { 1., 2., 3., 4., 6. };
std::cout << "Data: " << lar::dump::array<5>(data) << std::endl;

will produce an output like:

Data: { 1; 2; 3; 4; 6 }

Addition of specific classes can be achieved via specialization of the class ArrayDumper.

Requirements

• the type Array is required to respond to a global function cbegin() (like std::cbegin()) with a forward iterator
• the value type of the iterator returned by the aforementioned Array method must have its insertion operator into a stream defined
• the array a must not fall out of scope until the insertion into the stream happens

Definition at line 228 of file DumpUtils.h.

{ return ArrayDumper<Array>(a, N); }

template<typename String , typename Vector >

String lar::dump::operator+	(	String const &	s,
		VectorDumper< Vector > const &	manip
	)

Concatenates a vector to the specified string.

Template Parameters

String	a string type that can handle "addition" to std::string
Vector3D	the type of 3D vector to be printed

Parameters

s	the string
manip	the manipulator containing the vector to be printed

Returns

a new string with s concatenated to a rendering of the vector

See Also

VectorDumper

Example of usage:

TVector3 pos;
std::runtime_error e("Position: " + lar::dump::vector3D(pos));
std::cout << e.what() << std::endl;

will produce an output like:

Position: { 0; 0; 0 }

Requirements

• the type Vector3D is required to provide constant accessor methods returning the vector components, called X(), Y() and Z()
• the values returned by the aforementioned Vector3D methods must have their insertion operator into Stream defined

Definition at line 404 of file DumpUtils.h.

      { return s + std::string(manip);}

template<typename Vector >

std::string lar::dump::operator+	(	const char *	s,
		VectorDumper< Vector > const &	manip
	)

Creates a string with s concatenated to the rendered vector.

Definition at line 409 of file DumpUtils.h.

      { return std::string(s) + manip;}

template<typename String , typename Vector >

String lar::dump::operator+	(	VectorDumper< Vector > const &	manip,
		String const &	s
	)

See Also

documentation of function with arguments swapped.

Definition at line 414 of file DumpUtils.h.

      { return std::string(manip) + s;}

template<typename Vector >

std::string lar::dump::operator+	(	VectorDumper< Vector > const &	manip,
		const char *	s
	)

Creates a string with the rendered vector concatenated to s.

Definition at line 419 of file DumpUtils.h.

      { return manip + std::string(s);}

template<typename String , typename Vector >

String& lar::dump::operator+=	(	String &	s,
		VectorDumper< Vector > const &	manip
	)

Appends a string rendering of a vector to the specified string.

Definition at line 424 of file DumpUtils.h.

      { return s += std::string(manip); }

template<typename Stream , typename Array >

Stream& lar::dump::operator<<	(	Stream &&	out,
		ArrayDumper< Array > &&	manip
	)

Dumps the array contained in the manipulator into a stream.

Template Parameters

Stream	the type of output stream
Array	the type of array to be printed
NPrint	the number of element of the array to be printed

Parameters

out	the output stream
manip	the manipulator containing the array to be printed

Returns

a reference to the output stream

ArrayDumper

Example of usage:

double const data[5] = { 1., 2., 3., 4., 6. };
std::cout << "Position: " << lar::dump::array<5>(data) << std::endl;

will produce an output like:

Position: { 1, 2, 3, 4, 5 }

Requirements

• the type Vector3D is required to provide constant accessor methods returning the vector components, called X(), Y() and Z()
• the values returned by the aforementioned Vector3D methods must have their insertion operator into Stream defined

Definition at line 336 of file DumpUtils.h.

      { manip(std::forward<Stream>(out)); return out; }

template<typename Stream , typename Vector >

Stream& lar::dump::operator<<	(	Stream &&	out,
		VectorDumper< Vector > &&	manip
	)

Dumps the vector contained in the manipulator into a stream.

Template Parameters

Stream	the type of output stream
Vector3D	the type of 3D vector to be printed

Parameters

out	the output stream
manip	the manipulator containing the vector to be printed

Returns

a reference to the output stream

VectorDumper

Example of usage:

TVector3 pos;
std::cout << "Position: " << lar::dump::vector3D(pos) << std::endl;

will produce an output like:

Position: { 0; 0; 0 }

Requirements

• the type Vector3D is required to provide constant accessor methods returning the vector components, called X(), Y() and Z()
• the values returned by the aforementioned Vector3D methods must have their insertion operator into Stream defined

Definition at line 370 of file DumpUtils.h.

      { manip(std::forward<Stream>(out)); return out; }

template<typename Vector >

auto lar::dump::vector

(

Vector const &

v

)

Returns a manipulator which will print the specified array.

Template Parameters

Vector

type of vector to be printed

Parameters

v	the vector to be printed

Returns

a manipulator

Example of usage:

std::vector<double> data = { 1., 2., 3., 4., 6. };
std::cout << "Data: " << lar::dump::vector(data) << std::endl;

will produce an output like:

Data: { 1; 2; 3; 4; 6 }

Addition of specific classes can be achieved via specialization of the class ArrayDumper.

Requirements

• a method Vector::size() const must be available returning the number of elements in the vector
• the type Vector is required to respond to a global function cbegin() (like std::cbegin()) with a forward iterator
• the value type returned by the aforementioned Vector method must have its insertion operator into a stream defined
• the vector v must not fall out of scope until the insertion into the stream happens

Parameters

v	the vector to be printed

Returns

a manipulator

Example of usage:

TVector3 pos;
std::cout << "Position: " << lar::dump::vector3D(pos) << std::endl;
