## Detailed Description

A call to an overloaded operator written using operator syntax.

Represents a call to an overloaded operator written using operator syntax, e.g., "x + y" or "*p". While semantically equivalent to a normal call, this AST node provides better information about the syntactic representation of the call.

In a C++ template, this expression node kind will be used whenever any of the arguments are type-dependent. In this case, the function itself will be a (possibly empty) set of functions and function templates that were found by name lookup at template definition time.

## ◆ getOperatorLoc()

SourceLocation clang::CXXOperatorCallExpr::getOperatorLoc | ( |  | ) | const

Returns the location of the operator symbol in the expression.

When `getOperator()==OO_Call`, this is the location of the right parentheses; when `getOperator()==OO_Subscript`, this is the location of the right bracket.
