◆ LoadDepFile()

bool ImplicitDepLoader::LoadDepFile ( Edge *  edge,
const std::string &  path,
std::string *  err 
)
private

Load implicit dependencies for edge from a depfile attribute.

Returns
false on error (without filling err if info is just missing).

bool ImplicitDepLoader::LoadDeps ( Edge *  edge,
std::string *  err

◆ LoadDepsFromLog()

bool ImplicitDepLoader::LoadDepsFromLog ( Edge *  edge,
std::string *  err 
)
private

Load implicit dependencies for edge from the DepsLog.

Returns
false on error (without filling err if info is just missing).

◆ PreallocateSpace()

vector< Node * >::iterator ImplicitDepLoader::PreallocateSpace ( Edge *  edge,
int  count 
)
private

Preallocate count spaces in the input array on edge, returning an iterator pointing at the first new space.
