Member Function Documentation

◆ getJITDylib()

JITDylib & llvm::orc::ResourceTracker::getJITDylib ( ) const
inline

Return the JITDylib targeted by this tracker.

Definition at line 93 of file Core.h.

References JITDylib.

Referenced by llvm::orc::RedirectableSymbolManager::createRedirectableSymbols(), llvm::orc::COFFPlatform::notifyAdding(), llvm::orc::ELFNixPlatform::notifyAdding(), llvm::orc::MachOPlatform::notifyAdding(), remove(), transferTo(), withResourceKeyDo(), and ~ResourceTracker().

◆ getKeyUnsafe()

ResourceKey llvm::orc::ResourceTracker::getKeyUnsafe ( ) const
inline

Returns the key associated with this tracker.

This method should not be used except for debug logging: there is no guarantee that the returned value will remain valid.

Definition at line 115 of file Core.h.

Referenced by withResourceKeyDo().

◆ isDefunct()

bool llvm::orc::ResourceTracker::isDefunct ( ) const
inline

Return true if this tracker has become defunct.

Definition at line 110 of file Core.h.

Referenced by withResourceKeyDo().

◆ operator=() [1/2]

ResourceTracker & llvm::orc::ResourceTracker::operator= ( const ResourceTracker & )
delete

References ResourceTracker().

◆ operator=() [2/2]

ResourceTracker & llvm::orc::ResourceTracker::operator= ( ResourceTracker && )
delete

References LLVM_ABI, and ResourceTracker().

◆ remove()

Error llvm::orc::ResourceTracker::remove ( )

Remove all resources associated with this key.

Definition at line 55 of file Core.cpp.

References llvm::orc::JITDylib::getExecutionSession(), and getJITDylib().

Referenced by LLVMOrcResourceTrackerRemove().

◆ transferTo()

void llvm::orc::ResourceTracker::transferTo ( ResourceTracker & DstRT)

Transfer all resources associated with this key to the given tracker, which must target the same JITDylib as this one.

Definition at line 59 of file Core.cpp.

References llvm::orc::JITDylib::getExecutionSession(), getJITDylib(), and ResourceTracker().

Referenced by LLVMOrcResourceTrackerTransferTo().

◆ withResourceKeyDo()

template<typename Func>
Error llvm::orc::ResourceTracker::withResourceKeyDo ( Func && F)

Runs the given callback under the session lock, passing in the associated ResourceKey.

This is the safe way to associate resources with trackers.

Definition at line 1850 of file Core.h.
