Methods

¶CXXAllocatorCall(
    const clang::CXXNewExpr* E,
    clang::ento::ProgramStateRef St,
    const clang::LocationContext* LCtx)

Declared at: clang/include/clang/StaticAnalyzer/Core/PathSensitive/CallEvent.h:1003

Parameters

const clang::CXXNewExpr* E

clang::ento::ProgramStateRef St

const clang::LocationContext* LCtx

¶CXXAllocatorCall(
    const clang::ento::CXXAllocatorCall& Other)

Declared at: clang/include/clang/StaticAnalyzer/Core/PathSensitive/CallEvent.h:1006

Parameters

const clang::ento::CXXAllocatorCall& Other

¶static bool classof(
    const clang::ento::CallEvent* CE)

Declared at: clang/include/clang/StaticAnalyzer/Core/PathSensitive/CallEvent.h:1054

Parameters

const clang::ento::CallEvent* CE

¶void cloneTo(void* Dest) const

Description

Copies this CallEvent, with vtable intact, into a new block of memory.

Declared at: clang/include/clang/StaticAnalyzer/Core/PathSensitive/CallEvent.h:1008

Parameters

void* Dest

¶const clang::Expr* getArgExpr(
    unsigned int Index) const

Description

Returns the expression associated with a given argument. May be null if this expression does not appear in the source.

Declared at: clang/include/clang/StaticAnalyzer/Core/PathSensitive/CallEvent.h:1036

Parameters

unsigned int Index

¶const clang::FunctionDecl* getDecl() const

Description

Returns the declaration of the function or method that will be called. May be null.

Declared at: clang/include/clang/StaticAnalyzer/Core/PathSensitive/CallEvent.h:1015

¶clang::ento::CallEvent::Kind getKind() const

Description

Returns the kind of call this is.

Declared at: clang/include/clang/StaticAnalyzer/Core/PathSensitive/CallEvent.h:1051

¶llvm::StringRef getKindAsString() const

Declared at: clang/include/clang/StaticAnalyzer/Core/PathSensitive/CallEvent.h:1052

¶unsigned int getNumArgs() const

Description

Returns the number of arguments (explicit and implicit). Note that this may be greater than the number of parameters in the callee's declaration, and that it may include arguments not written in the source.

Declared at: clang/include/clang/StaticAnalyzer/Core/PathSensitive/CallEvent.h:1032

¶unsigned int getNumImplicitArgs() const

Description

Number of non-placement arguments to the call. It is equal to 2 for C++17 aligned operator new() calls that have alignment implicitly passed as the second argument, and to 1 for other operator new() calls.

Declared at: clang/include/clang/StaticAnalyzer/Core/PathSensitive/CallEvent.h:1028

¶clang::ento::SVal getObjectUnderConstruction()
    const

Declared at: clang/include/clang/StaticAnalyzer/Core/PathSensitive/CallEvent.h:1019

¶const clang::CXXNewExpr* getOriginExpr() const

Description

Returns the expression whose value will be the result of this call. May be null.

Declared at: clang/include/clang/StaticAnalyzer/Core/PathSensitive/CallEvent.h:1011

¶const clang::Expr* getPlacementArgExpr(
    unsigned int Index) const

Description

Number of placement arguments to the operator new() call. For example, standard std::nothrow operator new and standard placement new both have 1 implicit argument (size) and 1 placement argument, while regular operator new() has 1 implicit argument and 0 placement arguments.

Declared at: clang/include/clang/StaticAnalyzer/Core/PathSensitive/CallEvent.h:1047

Parameters

unsigned int Index
