Detailed Description

A Binding pairs a variable name with an expression.

It corresponds to the Declaration interface defined in https://github.com/unicode-org/message-format-wg/blob/main/spec/data-model.md#messages

Binding is immutable and copyable. It is not movable.

Constructor & Destructor Documentation

◆ Binding() [1/3]

icu::message2::data_model::Binding::Binding	(	const VariableName &	v,
		Expression &&	e
	)

inline

Constructor.

Parameters

v	A variable name.
e	An expression.

Deprecated:: This API is for technology preview only.

Definition at line 2088 of file messageformat2_data_model.h.

◆ Binding() [2/3]

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

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.

◆ Binding() [3/3]

icu::message2::data_model::Binding::Binding ( )

inline

Default constructor.

Puts the Binding into a valid but undefined state.

Deprecated:: This API is for technology preview only.

Member Function Documentation

◆ getValue()

const Expression& icu::message2::data_model::Binding::getValue ( ) const

Accesses the right-hand side of a binding.

Returns: A reference to the expression.

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

Deprecated:: This API is for technology preview only.

◆ getVariable()

const VariableName& icu::message2::data_model::Binding::getVariable ( ) const

inline

Accesses the left-hand side of the binding.

Returns: A reference to the variable name.

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 2055 of file messageformat2_data_model.h.

◆ input()

static Binding icu::message2::data_model::Binding::input	(	UnicodeString &&	variableName,
		Expression &&	rhs,
		UErrorCode &	errorCode
	)

static

Constructor for input binding.

Parameters

variableName	The variable name (left-hand side) of the binding. Passed by move.
rhs	The right-hand side of the input binding. Passed by move. `rhs` must have an operand that is a variable reference to `variableName`. If `rhs` has an operator, it must be a function call. If either of these properties is violated, `errorCode` is set to U_INVALID_STATE_ERROR.
errorCode	Input/output error code

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

Deprecated:: This API is for technology preview only.

◆ isLocal()

UBool icu::message2::data_model::Binding::isLocal ( ) const

inline

Returns true if and only if this binding represents a local declaration.

Otherwise, it's an input declaration.

Returns: True if this binding represents a variable and expression; false if it represents a variable plus an annotation.

Definition at line 2078 of file messageformat2_data_model.h.

◆ operator=()

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

noexcept

Copy 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.

Parameters
