Member Function Documentation

Add()

uint32_t ConstStringTable::Add

(

ConstString

s

)

Add a string into the string table.

Add a string to the string table will only add the same string one time and will return the offset in the string table buffer to that string. String tables are easy to build with ConstString objects since most LLDB classes for symbol or debug info use them already and they provide permanent storage for the string.

Parameters

s	The string to insert into the string table.

Returns

The byte offset from the start of the string table for the inserted string. Duplicate strings that get inserted will return the same byte offset.
