Member Function Documentation

getJITDylib()

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

inline

Return the JITDylib targeted by this tracker.

Definition at line 71 of file Core.h.

Referenced by 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.

isDefunct()

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

inline

Return true if this tracker has become defunct.

Definition at line 88 of file Core.h.

Referenced by withResourceKeyDo().

operator=() [1/2]

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

delete

operator=() [2/2]

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

delete

remove()

Error llvm::orc::ResourceTracker::remove

(

)

Remove all resources associated with this key.

Definition at line 54 of file Core.cpp.

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

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 58 of file Core.cpp.

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.
