Function Documentation

expect_tokens_eq() [1/2]

static void expect_tokens_eq ( const DynList< string > &  expected, const Array< string > &  got  )

static

Assert that a DynList of strings and an Array of strings contain the same tokens.

Compares sizes and each corresponding element; triggers test failures if the number of tokens differs or any element mismatches.

Parameters

expected	Expected tokens as a DynList<string>.
got	Actual tokens as an Array<string>.

Definition at line 117 of file ah-string-utils.cc.

References Aleph::divide_and_conquer_partition_dp().

expect_tokens_eq() [2/2]

static void expect_tokens_eq ( const DynList< string > &  expected, const DynList< string > &  got  )

static

Asserts that two DynList<string> contain the same tokens in the same order.

Compares the lists' sizes with ASSERT_EQ (which aborts the test on mismatch) and then compares each corresponding element with EXPECT_EQ.

Parameters

expected	The expected list of tokens.
got	The actual list of tokens to verify.

reference_split_string()

static DynList< string > reference_split_string ( const string &  s, const string &  delim  )

static

Splits a string into non-empty tokens using a set of delimiter characters.

Parameters

s	Input string to split.
delim	A string whose characters are treated as delimiter characters; each occurrence separates tokens. If delim is empty, the entire input is returned as a single token (unless s is empty).

Returns

DynList<string> A list of tokens where each token is a maximal substring of s that contains no characters from delim. Empty tokens are omitted.
