Public Member Functions
NumericVariable (StringRef Name, ExpressionFormat ImplicitFormat, std::optional< size_t > DefLineNumber=std::nullopt)
Constructor for a variable Name with implicit format ImplicitFormat defined at line DefLineNumber or defined before input is parsed if DefLineNumber is std::nullopt.
StringRef getName () const
ExpressionFormat getImplicitFormat () const
std::optional< APInt > getValue () const
std::optional< StringRef > getStringValue () const
void setValue (APInt NewValue, std::optional< StringRef > NewStrValue=std::nullopt)
Sets value of this numeric variable to NewValue, and sets the input buffer string from which it was parsed to NewStrValue.
void clearValue ()
Clears value of this numeric variable, regardless of whether it is currently defined or not.

llvm::NumericVariable::NumericVariable ( StringRef Name, ExpressionFormat ImplicitFormat, std::optional< size_t > DefLineNumber = std::nullopt ) inlineexplicit

Constructor for a variable Name with implicit format ImplicitFormat defined at line DefLineNumber or defined before input is parsed if DefLineNumber is std::nullopt.

Definition at line 236 of file FileCheckImpl.h.

◆ clearValue()

void llvm::NumericVariable::clearValue ( ) inline

Clears value of this numeric variable, regardless of whether it is currently defined or not.

Definition at line 268 of file FileCheckImpl.h.

◆ getDefLineNumber()

std::optional< size_t > llvm::NumericVariable::getDefLineNumber ( ) const inline

Returns

the line number where this variable is defined, if any, or std::nullopt if defined before input is parsed.

Definition at line 275 of file FileCheckImpl.h.

◆ getImplicitFormat()

◆ getName()

StringRef llvm::NumericVariable::getName ( ) const inline

◆ getStringValue()

std::optional< StringRef > llvm::NumericVariable::getStringValue ( ) const inline

Returns

the input buffer's string from which this variable's value was parsed, or std::nullopt if the value is not yet defined or was not parsed from the input buffer. For example, the value of @LINE is not parsed from the input buffer, and some numeric variables are parsed from the command line instead.

Definition at line 255 of file FileCheckImpl.h.

◆ getValue()

std::optional< APInt > llvm::NumericVariable::getValue ( ) const inline

◆ setValue()

void llvm::NumericVariable::setValue ( APInt NewValue, std::optional< StringRef > NewStrValue = std::nullopt ) inline

Sets value of this numeric variable to NewValue, and sets the input buffer string from which it was parsed to NewStrValue.

See comments on getStringValue for a discussion of when the latter can be std::nullopt.
