Member Data Documentation

Expr* clang::sema::TemplateDeductionInfo::Expression

The expression which caused a deduction failure.

TDK_FailedOverloadResolution: this argument is the reference to an overloaded function which could not be resolved to a specific function.

Definition at line 161 of file TemplateDeduction.h.

Referenced by clang::MakeDeductionFailureInfo().

TemplateArgument clang::sema::TemplateDeductionInfo::FirstArg

The first template argument to which the template argument deduction failure refers.

Depending on the result of the template argument deduction, this template argument may have different meanings:

TDK_Inconsistent: this argument is the first value deduced for the corresponding template parameter.

TDK_SubstitutionFailure: this argument is the template argument we were instantiating when we encountered an error.

TDK_NonDeducedMismatch: this is the component of the 'parameter' of the deduction, directly provided in the source code.

Definition at line 145 of file TemplateDeduction.h.

Referenced by clang::MakeDeductionFailureInfo().

TemplateParameter clang::sema::TemplateDeductionInfo::Param

The template parameter to which a template argument deduction failure refers.

Depending on the result of template argument deduction, this template parameter may have different meanings:

TDK_Incomplete: this is the first template parameter whose corresponding template argument was not deduced.

TDK_Inconsistent: this is the template parameter for which two different template argument values were deduced.

Definition at line 129 of file TemplateDeduction.h.

Referenced by clang::Sema::FinishTemplateArgumentDeduction(), clang::MakeDeductionFailureInfo(), and clang::Sema::SubstituteExplicitTemplateArguments().

SmallVector<DeducedPack *, 8> clang::sema::TemplateDeductionInfo::PendingDeducedPacks

Information on packs that we're currently expanding.

FIXME: This should be kept internal to SemaTemplateDeduction.

Definition at line 166 of file TemplateDeduction.h.

TemplateArgument clang::sema::TemplateDeductionInfo::SecondArg

The second template argument to which the template argument deduction failure refers.

TDK_NonDeducedMismatch: this is the mismatching component of the 'argument' of the deduction, from which we are deducing arguments.

FIXME: Finish documenting this.
