Detailed Description

Take input from keyboard and display it on screen. Usually just holds a string of letters and numbers representing a term.

Constructor & Destructor Documentation

Input::Input	(	Parser &	p,
		Node *	parent = `nullptr`
	)

Constructor using a text parser for input.

Parameters

p	Input parser.
parent	Parent of this input node.

Input::Input	(	Equation &	eqn,
		std::string	txt = `std::string()`,
		bool	current = `true`,
		Node *	parent = `nullptr`,
		bool	neg = `false`,
		Node::Select	s = `Node::Select::NONE`
	)

Constructor directly taking all needed parameters.

Parameters

eqn	Equation holding this input.
txt	Text stored from keyboard.
current	True if active.
parent	Parent node.
neg	True if negative sign.
s	Selection state.

Input::Input	(	EqnXMLParser &	in,
		Node *	parent
	)

Constructor using xml for input

Parameters

in	XML input stream.
parent	Parent of this input node.

Member Function Documentation

void Input::add ( char ch )

inline

Add charactor to end of input buffer.

Parameters

ch	Character to add to end of buffer.

void Input::add ( const std::string & s )

inline

Add string to end of input buffer.

Parameters

s	String to add to end of buffer.

void Input::calcOrig	(	UI::Graphics &	gc,
		int	x,
		int	y
	)

privatevirtual

Calculate origin of this node offset from the point (x,y) given it.

Parameters

gc	Graphics context.
x	Horizontal origin.
y	Vertical origin.

Implements Node.

Node::Frame Input::calcSize ( UI::Graphics & gc )

privatevirtual

Calculate size of this node in given graphics context.

Parameters

gc	Graphics context.

Returns: Return frame containing size of this node.

Implements Node.

bool Input::checkSN ( int sn )

inline

Check if serial number matches this node.

Parameters

sn	Serial number to check.

Returns: True if serial number matches.

void Input::clear ( )

inline

Clear input buffer.

void Input::drawNode ( UI::Graphics & gc ) const

privatevirtual

Draw this node in the given graphical context.

Parameters

gc	Graphical context.

Implements Node.

bool Input::empty ( ) const

inline

Check if input buffer is empty.

Returns: True if input buffer is empty

FactorIterator Input::emptyBuffer ( )

Parse and empty the conents of the input buffer. Parse the contents of the buffer and insert them before the Input object. Clear the contents of the buffer and return iterator to new position of Input object.

Returns: Iterator to current position of this object.

const std::string& Input::getBuffer ( )

inline

Get input buffer.

Returns: Reference to input buffer.

bool Input::getCurrent ( )

inline

Get state of this node being the active input.

Returns: If true, this is the current input.

const std::string& Input::getName ( ) const

inlinevirtual

Get name of this class.

Returns: Name of this class.

Implements Node.

Complex Input::getNodeValue ( ) const

privatevirtual

Throw an error if this is called.

Returns: Nothing is ever returned.

Implements Node.

std::type_index Input::getType ( ) const

inlinevirtual

Get type of this class.

Returns: Type of this class.

Implements Node.

void Input::makeCurrent ( )

inline

Make this node the current input.

int Input::numFactors ( ) const

inlinevirtual

Get number of factors in this node.

Returns: Number of factors.

Reimplemented from Node.

Input * Input::parse	(	Parser &	p,
		Node *	parent = `nullptr`
	)

static

Static helper function to parse Input class. Parser class object should be pointing to a string representation of an input node.

Parameters

p	Parser class object.
parent	Parent of return Input class object.

Returns: Newly created Input class object.

void Input::remove ( )

inline

Remove character from end of input buffer.

void Input::setCurrent ( bool current )

inline

Set state of this node being the active input.

Parameters

current True, if current active input.

string Input::toString ( ) const

virtual

Output text repesentation of input node. If empty output a '?' or a '#' if active. Otherwise '[typed_text]'.

Returns: String containing text representation.

Implements Node.

bool Input::unremovable ( )

inline

Determine if input is to be removed when deactivated. Input nodes that are empy and the only factor in their term should not be removed when deactivated. All others are.

Returns: True if input node should be removed when deactivated.

void Input::xml_out ( XML::Stream & xml ) const

privatevirtual

Output XML of this node.

Parameters

xml	XML output stream.

Implements Node.
