◆ SymbolPredicate

using llvm::orc::EPCDynamicLibrarySearchGenerator::SymbolPredicate = unique_function<bool(const SymbolStringPtr &)>

Definition at line 27 of file EPCDynamicLibrarySearchGenerator.h.

Constructor & Destructor Documentation

◆ EPCDynamicLibrarySearchGenerator()

llvm::orc::EPCDynamicLibrarySearchGenerator::EPCDynamicLibrarySearchGenerator	(	ExecutionSession &	ES,
		tpctypes::DylibHandle	H,
		SymbolPredicate	Allow = `SymbolPredicate()`
	)

inline

Create a DynamicLibrarySearchGenerator that searches for symbols in the library with the given handle.

If the Allow predicate is given then only symbols matching the predicate will be searched for. If the predicate is not given then all symbols will be searched for.

		SymbolPredicate	Allow = `SymbolPredicate()`
	)

static

Permanently loads the library at the given path and, on success, returns a DynamicLibrarySearchGenerator that will search it for symbol definitions in the library.

On failure returns the reason the library failed to load.

overridevirtual

DefinitionGenerators should override this method to insert new definitions into the parent JITDylib.

K specifies the kind of this lookup. JD specifies the target JITDylib being searched, and JDLookupFlags specifies whether the search should match against hidden symbols. Finally, Symbols describes the set of unresolved symbols and their associated lookup flags.

Implements llvm::orc::DefinitionGenerator.
