Detailed Description

template<typename IDField, typename... Fields>
class llvm::BCGenericRecordLayout< IDField, Fields >

Represents a single bitcode record type.

This class template is meant to be instantiated and then given a name, so that from then on that name can be used.

Constructor & Destructor Documentation

BCGenericRecordLayout()

template<typename IDField, typename... Fields>

llvm::BCGenericRecordLayout< IDField, Fields >::BCGenericRecordLayout ( llvm::BitstreamWriter & Stream )

inlineexplicit

Create a layout and register it with the given bitstream writer.

Member Function Documentation

emit()

template<typename IDField, typename... Fields>

template<typename BufferTy, typename... Data>

void llvm::BCGenericRecordLayout< IDField, Fields >::emit ( BufferTy & buffer, unsigned id, Data &&... data ) const

inline

Emit a record to the bitstream writer, using the given buffer for scratch space.

Note that even fixed arguments must be specified here.

Definition at line 376 of file BitcodeConvenience.h.

emitAbbrev()

template<typename IDField, typename... Fields>

unsigned llvm::BCGenericRecordLayout< IDField, Fields >::emitAbbrev ( llvm::BitstreamWriter & Stream )

inlinestatic

Registers this record's layout with the bitstream reader.

eturns The abbreviation code for the newly-registered record type.

Definition at line 383 of file BitcodeConvenience.h.

emitRecord()

template<typename IDField, typename... Fields>

template<typename BufferTy, typename... Data>

void llvm::BCGenericRecordLayout< IDField, Fields >::emitRecord ( llvm::BitstreamWriter & Stream, BufferTy & buffer, unsigned abbrCode, unsigned recordID, Data &&... data )

inlinestatic

Emit a record identified by abbrCode to bitstream reader Stream, using buffer for scratch space.

Note that even fixed arguments must be specified here. Blobs are passed as StringRefs, while arrays can be passed inline, as aggregates, or as pre-encoded StringRef data. Skipped values and empty arrays should use the special Nothing value.

readRecord() [1/2]

template<typename IDField, typename... Fields>

template<typename ElementTy, typename... Data>

void llvm::BCGenericRecordLayout< IDField, Fields >::readRecord ( ArrayRef< ElementTy > buffer, Data &&... data )

inlinestatic

Extract record data from buffer into the given data fields.

Note that even fixed arguments must be specified here. Pass Nothing if you don't care about a particular parameter. Blob data is not included in the buffer and should be handled separately by the caller.

readRecord() [2/2]

template<typename IDField, typename... Fields>

template<typename BufferTy, typename... Data>

void llvm::BCGenericRecordLayout< IDField, Fields >::readRecord ( BufferTy & buffer, Data &&... data )

inlinestatic

Extract record data from buffer into the given data fields.

Note that even fixed arguments must be specified here. Pass Nothing if you don't care about a particular parameter. Blob data is not included in the buffer and should be handled separately by the caller.

AbbrevCode

template<typename IDField, typename... Fields>

const unsigned llvm::BCGenericRecordLayout< IDField, Fields >::AbbrevCode
