Member Function Documentation

add() [1/2]

size_t StringTableBuilder::add

(

CachedHashStringRef

S

)

Add a string to the builder.

Returns the position of S in the table. The position will be changed if finalize is used. Can only be used before the table is finalized.

clear()

void StringTableBuilder::clear

Definition at line 165 of file StringTableBuilder.cpp.

Referenced by getSize(), and llvm::MachObjectWriter::reset().

finalize()

void StringTableBuilder::finalize

(

)

Analyze the strings and build the final table.

No more strings can be added after this point.

References assert(), and DWARF.

Referenced by add(), and llvm::MachObjectWriter::computeSymbolTable().

finalizeInOrder()

void StringTableBuilder::finalizeInOrder

(

)

Finalize the string table without reording it.

In this mode, offsets returned by add will still be valid.

getOffset() [1/2]

size_t StringTableBuilder::getOffset

const

Get the offest of a string in the string table.

Can only be used after the table is finalized.
