edm::TypeWithDict helper::Parser::elementType ( const edm::TypeWithDict &  wrapperType )

static

Perform the type deduction form edm::Wrapper<C> to C::value_type and resolves typedefs.

Definition at line 39 of file ScannerHelpers.cc.

double helper::Parser::eval ( const reco::parser::ExpressionPtr &  sel, const edm::TypeWithDict  type, const void *  obj  )

static

Make a edm::ObjectWithDict(type, obj) and pass it to the expression.

Definition at line 57 of file ScannerHelpers.cc.

reco::parser::ExpressionPtr helper::Parser::makeExpression ( const std::string &  expr, const edm::TypeWithDict &  type  )

static

Parse an expression for a given object type (using lazy parsing when resolving methods)

NOTA BENE: <0> for cuts, <1> for expresions (why? boh!)

bool helper::Parser::test ( const reco::parser::SelectorPtr &  sel, const edm::TypeWithDict  type, const void *  obj  )

static
