Referenced by erase().

erase()

bool MDAttachments::erase

(

unsigned

ID

)

Remove attachments with the given ID.

Remove the attachments at ID, if any.

get()

void MDAttachments::get	(	unsigned	ID,
		SmallVectorImpl< MDNode * > &	Result ) const

Appends all attachments with the given ID to Result in insertion order.

If the global has no attachments with the given ID, or if ID is invalid, leaves Result unchanged.

Definition at line 1494 of file Metadata.cpp.

References A().

getAll()

void MDAttachments::getAll

(

SmallVectorImpl< std::pair< unsigned, MDNode * > > &

Result

)

const

Appends all attachments for the global to Result, sorting by attachment ID.

Attachments with the same ID appear in insertion order. This function does not clear Result.

Definition at line 1500 of file Metadata.cpp.

References A(), and llvm::stable_sort().

insert()

void MDAttachments::insert	(	unsigned	ID,
		MDNode &	MD )

Adds an attachment to a particular node.

Definition at line 1517 of file Metadata.cpp.

Referenced by set().

lookup()

MDNode * MDAttachments::lookup

(

unsigned

ID

)

const

Returns the first attachment with the given ID or nullptr if no such attachment exists.

Definition at line 1487 of file Metadata.cpp.

remove_if()

template<class PredTy>

void llvm::MDAttachments::remove_if ( PredTy shouldRemove )

inline

Erase matching attachments.

Erases all attachments matching the shouldRemove predicate.

Definition at line 1612 of file LLVMContextImpl.h.

References llvm::erase_if().

set()

void MDAttachments::set	(	unsigned	ID,
		MDNode *	MD )

Set an attachment to a particular node.

Set the ID attachment to MD, replacing the current attachments at ID (if anyway).

Definition at line 1511 of file Metadata.cpp.

References erase(), and insert().

size()

size_t llvm::MDAttachments::size ( ) const
