Logical Tree - IBinding
§Logical elements are
higher-level constructs that map onto a physical IASTNode
§For 3.0 :
IASTName#resolveBinding()
•long x; /* IASTName for x resolves to an
IVariable */
•long y();
/* IASTName for y resolves to an IFunction */
•int f() { return
sizeof( int ); } /* IASTName for f resolves to an
IFunction*/
§Beyond 3.0 –
IASTBinaryExpression could bind to an user defined operator
§Semantic errors return
an IProblemBinding describing the error
§IASTTranslationUnit can
be asked for all declarations or references of a particular IBinding
§Bindings can be
resolved completely lazily on request or in a full traversal
of the AST
4Indexer would require
full binding resolution
4Most other clients do
not require all bindings to be resolved
