Detailed Description

The Literal class corresponds to the literal nonterminal in the MessageFormat 2 grammar, https://github.com/unicode-org/message-format-wg/blob/main/spec/message.abnf and the Literal interface defined in // https://github.com/unicode-org/message-format-wg/blob/main/spec/data-model.md#expressions.

Literal is immutable, copyable and movable.

Constructor & Destructor Documentation

◆ Literal() [1/3]

icu::message2::data_model::Literal::Literal	(	UBool	q,
		const UnicodeString &	s
	)

inline

Literal constructor.

Parameters

q	True if and only if this literal was parsed with the `quoted` nonterminal (appeared enclosed in '\|' characters in the message text).
s	The string contents of this literal; escape sequences are assumed to have been interpreted already.

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

Definition at line 117 of file messageformat2_data_model.h.

◆ Literal() [2/3]

icu::message2::data_model::Literal::Literal ( const Literal & other )

inline

Copy constructor.

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

Definition at line 124 of file messageformat2_data_model.h.

◆ Literal() [3/3]

icu::message2::data_model::Literal::Literal ( )

default

Default constructor.

Puts the Literal into a valid but undefined state.

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

◆ ~Literal()

virtual icu::message2::data_model::Literal::~Literal ( )

virtual

Destructor.

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

Member Function Documentation

◆ isQuoted()

UBool icu::message2::data_model::Literal::isQuoted ( ) const

inline

Determines if this literal appeared as a quoted literal in the message.

Returns: true if and only if this literal appeared as a quoted literal in the message.

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

Definition at line 105 of file messageformat2_data_model.h.

◆ operator<()

bool icu::message2::data_model::Literal::operator< ( const Literal & other ) const

Less than operator.

Compares this.stringContents() with other.stringContents(). This method is used in representing the mapping from key lists to patterns in a message with variants, and is not expected to be useful otherwise.

Parameters

other The Literal to compare to this one.

Returns: true if the parsed string corresponding to this Literal is less than the parsed string corresponding to the other Literal (according to UnicodeString's less-than operator). Returns false otherwise.

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

◆ operator=()

Literal & icu::message2::data_model::Literal::operator= ( Literal )

noexcept

Assignment operator.

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

◆ operator==()

bool icu::message2::data_model::Literal::operator== ( const Literal & other ) const

Equality operator.

Compares this.stringContents() with other.stringContents(). This method is used in representing the mapping from key lists to patterns in a message with variants, and is not expected to be useful otherwise.

Parameters

other The Literal to compare to this one.

Returns: true if the parsed string corresponding to this Literal equals the parsed string corresponding to the other Literal (according to UnicodeString's equality operator). Returns false otherwise.

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

◆ quoted()

UnicodeString icu::message2::data_model::Literal::quoted ( ) const

Returns the quoted representation of this literal (enclosed in '|' characters)

Returns: A string representation of the literal enclosed in quote characters.

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

◆ unquoted()

const UnicodeString & icu::message2::data_model::Literal::unquoted ( ) const

Returns the parsed string contents of this literal.

Returns: A string representation of this literal.

Internal:: Do not use. This API is for internal use only. ICU 75 technology preview

Deprecated:: This API is for technology preview only.

	)

friend

Non-member swap function.

Parameters

l1	will get l2's contents
l2	will get l1's contents
