Detailed Description

This struct provides a namespace for enumerating types used for command-line option values. See Enumerators for details.

This struct:

Supports a complete set of enumeration operations.
Provides several additional utility functions.

Member Function Documentation

static Enum balcl::OptionType::fromArrayType ( Enum type ) [static]

If isArrayType(type) for the specified type, then return the type of the elements of that array type; otherwise return e_VOID.

static bool balcl::OptionType::isArrayType ( Enum type ) [static]

Return true if the specified type corresponds to an array type, and false otherwise.

static Enum balcl::OptionType::toArrayType ( Enum type ) [static]

If there is an array type whose elements have the specified type then return that array type; otherwise return e_VOID. e_VOID == toArrayType(e_BOOL) because an array of boolean values is not allowed as a command-line-option type. Note that type == fromArrayType(TYPE) when TYPE != e_VOID is returned.

static bsl::ostream& balcl::OptionType::print	(	bsl::ostream &	stream,
		OptionType::Enum	value,
		int	level = `0`,
		int	spacesPerLevel = `4`
	)			`[static]`

Write the string representation of the specified enumeration value to the specified output stream, and return a reference to stream. Optionally specify an initial indentation level, whose absolute value is incremented recursively for nested objects. If level is specified, optionally specify spacesPerLevel, whose absolute value indicates the number of spaces per indentation level for this and all of its nested objects. If level is negative, suppress indentation of the first line. If spacesPerLevel is negative, format the entire output on one line, suppressing all but the initial indentation (as governed by level). See toAscii for what constitutes the string representation of a OptionType::Enum value.

static const char* balcl::OptionType::toAscii ( OptionType::Enum value ) [static]

Return the (non-modifiable) string representation corresponding to the specified enumeration value, if it exists, and a unique (error) string otherwise. The string representation of value matches its corresponding enumerator name with the e_ prefix elided. For example:

          bsl::cout << balcl::OptionType::toAscii(
                                            OptionType::e_STRING);

will print the following on standard output:

          STRING

Note that specifying a value that does not match any of the enumerators will result in a string representation that is distinct from any of those corresponding to the enumerators, but is otherwise unspecified.
