Member Enumeration Documentation

◆ switchType

enum switchType : unsigned char

Switch enumerations corresponding to common text representations.

Note: The values here are critical for its proper behaviour. The values correspond to an index into the predefined output names for the c_str() method and the lower bit is tested for determining the true/false bool value.

Enumerator
FALSE	"false"
TRUE	"true"
NO	"no"
YES	"yes"
OFF	"off"
ON	"on"
NONE	"none"
ANY	"any"
INVALID	"invalid" (output only)

◆ Switch() [8/15]

Switch	(	const float	val,
		const float	tol = `0.5`
	)

explicit

Construct from float with rounding to zero given by the tolerance (default: 0.5)

Definition at line 200 of file Switch.C.

◆ Switch() [10/15]

Switch ( const token & tok )

explicit

Construct from token. Handles bool/label/word types.

Definition at line 212 of file Switch.C.

References bool, token::boolToken(), token::good(), token::isBool(), token::isLabel(), token::isWord(), token::labelToken(), and token::wordToken().

Here is the call graph for this function:

◆ Switch() [11/15]

Switch	(	const word &	key,
		const dictionary &	dict
	)

Construct from dictionary lookup.

FatalError if anything is incorrect.

Parameters

key	Lookup key. Uses LITERAL (not REGEX)
dict	dictionary

Definition at line 235 of file Switch.C.

References dict, Foam::exit(), Foam::FatalIOError, FatalIOErrorInFunction, dictionary::get(), Switch::good(), Foam::glTF::key(), keyType::LITERAL, and Foam::printTokenError().

Here is the call graph for this function:

◆ Switch() [12/15]

Switch	(	const word &	key,
		const dictionary &	dict,
		const Switch	deflt,
		const bool	failsafe = `false`
	)

Find the key in the dictionary and use the corresponding switch value or the default if not found in dictionary.

FatalIOError if the switch name is incorrect. Specifying failsafe downgrades the FatalIOError to an IOWarning.

Parameters

key	Lookup key. Uses LITERAL (not REGEX)
dict	dictionary
deflt	fallback if not found
failsafe	Warn only on bad input
