concatenate() [1/2]

static String concatenate ( const std::vector< T > &  container, const String &  glue = ""  )

inlinestatic

Concatenates all elements of the container and puts the glue string between elements.

Parameters

container	The container to concatenate;
glue	The string to add in between elements.

Referenced by RNPxlSearch::postScoreHits_().

concatenate() [2/2]

static String concatenate ( const T &  container, const String &  glue = ""  )

inlinestatic

Concatenates all elements of the container and puts the glue string between elements.

Parameters

container	The container <T> to concatenate; must have begin() and end() iterator.
glue	The string to add in between elements.

contains() [1/2]

static bool contains ( const std::vector< T > &  container, const E &  elem  )

inlinestatic

Checks whether the element elem is contained in the given container.

Parameters

container	The container to check.
elem	The element to check whether it is in the container or not.

Returns

True if elem is contained in container, false otherwise.

Referenced by HasActivationMethod< SpectrumType >::operator()(), and PeakPickerHiRes::pickExperiment().

contains() [2/2]

static bool contains ( const std::vector< double > &  container, const double &  elem, double  tolerance = 0.00001  )

inlinestatic

Checks whether the element elem is contained in the given container of floating point numbers.

Parameters

container	The container of doubles to check.
elem	The element to check whether it is in the container or not.
tolerance	The allowed tolerance for the double.

Returns

True if elem is contained in container, false otherwise.

create() [1/3]

static std::vector<T> create ( const String &  str, const char  splitter = ','  )

inlinestatic

Returns a list that is created by splitting the given comma-separated string.

Note

If converted to vector<String> the strings are not trimmed.

The values get converted by boost::lexical_cast so a valid conversion from String to T needs to be available.

Parameters

str	The string that should be split and converted to a list.

Returns

A vector containing the elements of the string converted into type T.

References String::split().

create() [2/3]

std::vector< T > create ( const std::vector< String > &  s )

inlinestatic

Converts a vector of strings to a vector of the target type T.

Note

The strings are not trimmed.

The values get converted by boost::lexical_cast so a valid conversion from String to T needs to be available.

Parameters

s	The vector of strings that should be converted.

Returns

A vector containing the elements of input vector converted into type T.

References OpenMS::Constants::c.

create() [3/3]

std::vector<String> create ( const std::vector< String > &  s )

inline

create specialization for String since we do not need to cast here

getIndex()

static Int getIndex ( const std::vector< T > &  container, const E &  elem  )

inlinestatic

Get the index of the first occurrence of an element in the vector (or -1 if not found)
