Member Function Documentation

checkPathInternal()

bool ClientScripting::checkPathInternal ( const std::string & abs_path, bool write_required, bool * write_allowed )

inlineoverrideprotectedvirtual

Should check if the given path may be accessed.

If write_required is true test for write access, if false test for read access.

Parameters

abs_path	absolute file/directory path, may not exist
write_required	was write access requested?
write_allowed	output parameter (nullable): set to true if writing is allowed

Returns

true if access is allowed

Implements ScriptApiSecurity.

Here is the caller graph for this function:

modNamesAreTrusted()

bool ClientScripting::modNamesAreTrusted ( )

inlineoverrideprotectedvirtual

Specify if the mod names during init time(!) can be trusted.

It needs to be assured that no tampering happens before any call to loadMod().

Note

disabling this implies that mod whitelisting never works

Returns

boolean value
