Detailed Description

Represents a function header definition in a Hermes bytecode file.

Member Function Documentation

ClearInstructionCache()

void Hasmer.HbcFuncHeader.ClearInstructionCache ( )

inline

Clears the instructions cache so that a future call to Disassemble will disassemble and re-cache the data from scratch.

Disassemble()

List<HbcInstruction> Hasmer.HbcFuncHeader.Disassemble ( )

inline

Disassembles the function, parsing the bytecode into an HbcInstruction object for each instruction.
The instructions will be cached. To clear the cache and have this function re-parse the instructions, see ClearInstructionCache.

GetAssemblerHeader()

virtual HbcFuncHeader Hasmer.HbcFuncHeader.GetAssemblerHeader ( )

inlinevirtual

Gets the header that should be used for disassembly and decompilation, i.e. the header that contains instructions. HbcSmallFuncHeader objects do not contain bodies, so this returns the large header for such objects.

Reimplemented in Hasmer.HbcSmallFuncHeader.

GetFunctionName()

string Hasmer.HbcFuncHeader.GetFunctionName ( HbcFile  source )

inline

Gets the name of a function, or the autogenerated name of a closure if it's an unnamed closure.

Property Documentation

BytecodeSizeInBytes

uint Hasmer.HbcFuncHeader.BytecodeSizeInBytes

getset

The amount of bytes that the function's bytecode takes up.

EnvironmentSize

uint Hasmer.HbcFuncHeader.EnvironmentSize

getset

The amount of symbols that the function has.

Flags

HbcFuncHeaderFlags Hasmer.HbcFuncHeader.Flags

getset

FrameSize

uint Hasmer.HbcFuncHeader.FrameSize

getset

The amount of registers that the function has.

FunctionId

uint Hasmer.HbcFuncHeader.FunctionId

getset

The sequential ID of the function.

FunctionName

uint Hasmer.HbcFuncHeader.FunctionName

getset

The index in the string table of the function's name (i.e. HbcFile.GetStringTableEntry(FunctionName)).

InfoOffset

uint Hasmer.HbcFuncHeader.InfoOffset

getset

The offset in the HbcFile of additional (i.e. debug) information about the function.

Offset

uint Hasmer.HbcFuncHeader.Offset

getset

The offset in the HbcFile of the function.

ParamCount

uint Hasmer.HbcFuncHeader.ParamCount

getset

The amount of parameters that the function takes.
