StringTableBuilder::~StringTableBuilder ( ) default

◆ add() [1/2]

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. Priority is only useful with reordering. Strings with the same priority will be put together. Strings with higher priority are placed closer to the begin of string table. When adding same string with different priority, the maximum priority win.

◆ contains() [2/2]

bool llvm::StringTableBuilder::contains ( StringRef S) const inline

Check if a string is contained in the string table.

Since this class doesn't store the string values, this function can be used to check if storage needs to be done prior to adding the string.
