Gets the number of all test parts. This is the sum of the number of successful test parts and the number of failed test parts.

Prints the message and aborts the program if condition is false.

FullMatch(str, re) returns true iff regular expression re matches the entire str. PartialMatch(str, re) returns true iff regular expression re matches

Returns true iff ch appears anywhere in str (excluding the terminating '\0' character).

Returns true if pathname describes a root directory. (Windows has one root directory per disk drive.)

Get the size of the latent factor. For linear score this value equals zero.

Parses a string for an Int32 flag, in the form of "--flag=value". On success, stores the value of the flag in *value, and returns true. On failure,

Read the whole file to a memory buffer. Return size (byte) of current file.

Returns a copy of the FilePath with the directory part removed. Example: FilePath("path/to/file").RemoveDirectoryName() returns FilePath("file"). If t

Mapping the global feature id to the local server id.

Given a feature id, return the server id, which stores that feature.

Parses the environment variable var as an Int32. If it is unset, returns default_val. If it is not an Int32, prints an error and aborts.

Reads and returns a 32-bit integer stored in the environment variable corresponding to the given flag; if it isn't set or doesn't represent a valid 32

Returns true iff the unit test passed (i.e. all test cases passed).

Reset current model parameters.

Sets the env variable to 'value'; unsets it when 'value' is None.

If *pstr starts with the given prefix, modifies *pstr to be right past the prefix and returns true; otherwise leaves *pstr unchanged and returns false
