XQuestResultXMLHandler ( const String filename,
std::vector< PeptideIdentification > &  pep_ids,
std::vector< ProteinIdentification > &  prot_ids 
)

Constructor for a read-only handler for internal identification structures.

◆ XQuestResultXMLHandler() [2/2]

XQuestResultXMLHandler ( const std::vector< ProteinIdentification > &  pro_id,
const std::vector< PeptideIdentification > &  pep_id,
const String filename,
const String version 
)

Constructor for a write-only handler for internal identification structures.

◆ ~XQuestResultXMLHandler()

~XQuestResultXMLHandler ( )
override

Member Function Documentation

◆ addMetaValues_()

void addMetaValues_ ( MetaInfoInterface meta_info_interface)
private

Assigns all meta values stored in the peptide_id_attributes member to an meta info interface.

Parameters
meta_info_interfaceWhere the meta values from the peptide_id_attributes member should be assigned to

◆ endElement()

void endElement ( const XMLCh *const  uri,
const XMLCh *const  local_name,
const XMLCh *const  qname 
)
override

◆ extractDateTime_()

void extractDateTime_ ( const String xquest_datetime_string,
DateTime date_time 
)
inlineprivate

Extracts the DateTime from datetime string from xQuest.

Parameters
xquest_datetime_stringThe DateTime String to be processed
date_timeDateTime that reflects the value given in the `xquest_datetime_string`

◆ getLinkPosition_()

void getLinkPosition_ ( const xercesc::Attributes &  attributes,
std::pair< SignedSize, SignedSize > &  pair 
)
private

Gets the link location of a xQuest xlinkPositionString.

Parameters
attributesXML attributes of Xerces.
pairPair to be populated with the xlinkposition in xQuest.

◆ getMaxScore()

double getMaxScore ( ) const

Returns the maximum score encountered in the file.

Returns
Maximum score encountered in the file.

◆ getMinScore()

double getMinScore ( ) const

Returns the minimum score encountered in the file.

Returns
Minimum score encountered in the file.

◆ getNumberOfHits()

UInt getNumberOfHits ( ) const

Returns the total number of hits in the file.

Returns
Total number of hits in the file.

◆ setPeptideEvidence_()

void setPeptideEvidence_ ( const String prot_string,
PeptideHit pep_hit 
)
private

Sets the peptide evidence for Alpha and Beta.

Parameters
prot_stringProtein string of the xquest file the peptide evidence should be populated from.
pep_hitFor which peptide hit the peptide evidence should be set.

◆ splitByMiddle()

static StringList splitByMiddle ( const String input,
const char  separator 
)
static

counts occurrences of the @separator and splits the @input string into two at the middle

If the separator occurs 5 times in the input string, the string will be split at the 3rd occurrence. If 7 times, then at the 4th. The separator has to occur in the string an uneven number of times. If the separator occurs once, the string will be split at this one instance. If this one occurrence is at the beginning or end, one of the result strings will be empty.

Exceptions
Exception::IllegalArgumentis thrown if the @separator does not occur in the @input string an uneven number of times and at least once
Returns
StringList with two elements, the two halves of the input without the middle separator

◆ splitByNth()

static StringList splitByNth ( const String input,
const char  separator,
const Size  n 
)
static

splits the @input string at the nth occurrence of the @separator

If the separator does not occur in the input string n times, then the first output string will be the entire input string and the second one will be empty.

Returns
StringList with two elements, the two parts of the input without the nth separator
