Detailed Description

An AST selection value that corresponds to a selection of a set of statements that belong to one body of code (like one function).

For example, the following selection in the source.

void function() {
 // selection begin:
 int x = 0;
 {
    // selection end
    x = 1;
 }
 x = 2;
}

Would correspond to a code range selection of statements "int x = 0" and the entire compound statement that follows it.

A CodeRangeASTSelection value stores references to the full SelectedASTNode tree and should not outlive it.

getFunctionLikeNearestParent()

(

const

Returns the nearest function-like parent declaration or null if such declaration doesn't exist.

References clang::DynTypedNode::get(), and isFunctionLikeDeclaration().

getParents()

ArrayRef< SelectedASTNode::ReferenceType > clang::tooling::CodeRangeASTSelection::getParents ( )

inline

Returns the parent hierarchy (top to bottom) for the selected nodes.

isInFunctionLikeBodyOfCode()

bool CodeRangeASTSelection::isInFunctionLikeBodyOfCode

(

)

const

Returns true when a selected code range is in a function-like body of code, like a function, method or a block.

This function can be used to test against selected expressions that are located outside of a function, e.g. global variable initializers, default argument values, or even template arguments.

Use the getFunctionLikeNearestParent to get the function-like parent declaration.
