Detailed Description

template<typename Container>
class ecl::formatters::FloatContainerFormatter< Container >

Parent interface for formatters of fixed size float/double containers.

This defines the common interface to be shared by fixed size float/double containers. It only allows configuration of width and precision to be used to format the elements of the container. Note that if the width is set to -1 (the default), this class automatically configures an appropriate width by scanning the elements within and setting it to the minimum width necessary to display all elements properly.

Do not use this class directly, rather call it via either the Container type or Format classes explicitly. This makes the code more readable. e.g.

Array<float>::Formatter format_array_1;

Format< Array<float,4> > format_array_2; // same thing

Template Parameters

Container : the underlying fixed size float or double array.

See also: ecl::formatters::Format< Array<float,N>, ecl::formatters::Format<Array<double,N>>.

Note, the above don't link properly to the partial specialisations. Look for them in the ecl::formatters namespace.

Member Typedef Documentation

◆ value_type

template<typename Container>

typedef Container::value_type ecl::formatters::FloatContainerFormatter< Container >::value_type

Catches the container element's type.

Definition at line 72 of file common/formatters.hpp.

Constructor & Destructor Documentation

◆ FloatContainerFormatter()

template<typename Container>

ecl::formatters::FloatContainerFormatter< Container >::FloatContainerFormatter	(	const unsigned int	p = `2`,
		const int	w = `-1`
	)

inline

Constructor - can be used to define the precision required for the formatter's elements.

Parameters

p	: the number of decimal places of precision [default : 2].
w	: width [default : no width constraint]

Definition at line 80 of file common/formatters.hpp.

◆ ~FloatContainerFormatter()

template<typename Container>

virtual ecl::formatters::FloatContainerFormatter< Container >::~FloatContainerFormatter ( )

inlinevirtual

Definition at line 90 of file common/formatters.hpp.

Member Function Documentation

◆ digits()

template<typename Container >

long ecl::formatters::FloatContainerFormatter< Container >::digits	(	value_type	min_coeff,
		value_type	max_coeff
	)

private

Compute the integral width. This accepts the minimum and maximum values in the array from which a minimum width that provides a common width for every element in the array to be fully displayed is determined.

Parameters

min_coeff	: the minimum value in the array.
max_coeff	: the maximum value in the array.

Returns: long : the width to use for the integral part of the co-efficients.

Definition at line 193 of file common/formatters.hpp.

◆ operator()() [1/3]

template<typename Container>

FloatContainerFormatter& ecl::formatters::FloatContainerFormatter< Container >::operator()	(	const unsigned int	p,
		const int	w
	)

inline

Permanently sets the stream's precision format. This is simply a convenient version of the precision(p) method.

Parameters

p	: the number of decimal places of precision.
w	: the width to use for the inserted float.

Returns: FloatContainerFormatter& : this formatter readied for use with a stream.

Definition at line 126 of file common/formatters.hpp.

◆ operator()() [2/3]

template<typename Container>

FloatContainerFormatter& ecl::formatters::FloatContainerFormatter< Container >::operator() ( const Container & c )

inline

Convenient stream formatter. This function directly readies the formatter with the specified container and the stored (permanent) settings.

Format< Array<float,N> > format;

cout << format(array) << endl;

Parameters

c	: the input container to be formatted.

Returns: FormatFloat& : this formatter readied for use with a stream.

Definition at line 137 of file common/formatters.hpp.

◆ operator()() [3/3]

template<typename Container>

FloatContainerFormatter& ecl::formatters::FloatContainerFormatter< Container >::operator()	(	Container &	c,
		const unsigned int	p,
		const int	w
	)

inline

Convenient stream formatter. This function directly readies the formatter with the specified container and configures a temporary setting for the precision (one-shot).

Format< Array<float,N> > format;

cout << format(array,2) << endl;

Parameters

c	: the input container to be formatted.
p	: the number of decimal places of precision.
w	: the width to use for the inserted float.

Returns: FormatFloat& : this formatter readied for use with a stream.

Definition at line 151 of file common/formatters.hpp.

◆ precision() [1/2]

template<typename Container>

FloatContainerFormatter& ecl::formatters::FloatContainerFormatter< Container >::precision ( const unsigned int p )

inline

Sets the precision format parameter.

Use this to set the precision of the displayed output.

Parameters

p	: the number of decimal places of precision.

Returns: FloatContainerFormatter& : this formatter readied for use with a stream.

Definition at line 100 of file common/formatters.hpp.

◆ precision() [2/2]

template<typename Container>

unsigned int ecl::formatters::FloatContainerFormatter< Container >::precision ( ) const

inline

Access the current precision used by this formatter.

Returns the current precision setting.

Returns: int : the number of decimal places of precision.

Definition at line 118 of file common/formatters.hpp.

◆ width()

template<typename Container>

FloatContainerFormatter& ecl::formatters::FloatContainerFormatter< Container >::width ( const int w )

inline

Sets the width format parameter.

Use this to configure the width of the displayed output. The formatter can be instructed to automatically determine a width suitable for all elements by setting this value to -1.

Parameters

w	: the width to use for the inserted float [-1 for automatic resizing of cells].

Returns: FloatContainerFormatter& : this formatter readied for use with a stream.

Definition at line 111 of file common/formatters.hpp.

◆ operator<<

template<typename Container>

template<typename OutputStream , typename Container_ >

OutputStream& operator<<	(	OutputStream &	ostream,
		FloatContainerFormatter< Container_ > &	formatter
	)

friend

Insertion operator for sending the formatter to an output stream.

Parameters

ostream	: the output stream.
formatter	: the formatter to be inserted.

Returns: OutputStream : continue streaming with the updated output stream.
