Detailed Description

Utility class to enable for-each style iteration in the MultipleVariantReader class.

Constructor & Destructor Documentation

gamgee::MultipleVariantIterator::MultipleVariantIterator ( )

default

creates an empty iterator (used for the end() method)

gamgee::MultipleVariantIterator::MultipleVariantIterator	(	const std::vector< std::shared_ptr< htsFile >> &	variant_files,
		const std::vector< std::shared_ptr< bcf_hdr_t >> &	variant_headers
	)

initializes a new iterator based on a vector of input files (vcf or bcf)

Parameters

variant_files	vector of vcf/bcf files opened via the bcf_open() macro from htslib
variant_headers	vector of headers corresponding to the files

gamgee::MultipleVariantIterator::MultipleVariantIterator ( MultipleVariantIterator &&  )

default

a MultipleVariantIterator move constructor guarantees all objects will have the same state.

gamgee::MultipleVariantIterator::MultipleVariantIterator ( const MultipleVariantIterator &  )

delete

a MultipleVariantIterator cannot be copied safely, as it is iterating over streams.

Member Function Documentation

bool gamgee::MultipleVariantIterator::operator!=

(

const MultipleVariantIterator &

rhs

)

pseudo-inequality operator (needed by for-each loop)

Warning

this method does the minimal work necessary to determine that we have reached the end of iteration. it is NOT a valid general-purpose inequality method.

Parameters

rhs	the other MultipleVariantIterator to compare to

Returns

whether both iterators have entered their end states

std::vector< VariantIndexPair > & gamgee::MultipleVariantIterator::operator*

(

)

dereference operator (needed by for-each loop)

Returns

a reference to the iterator's Variant vector

std::vector< VariantIndexPair > & gamgee::MultipleVariantIterator::operator++

(

)

advances the iterator, fetching the next vector

Returns

a reference to the iterator's Variant vector

MultipleVariantIterator& gamgee::MultipleVariantIterator::operator= ( MultipleVariantIterator &&  other )

default

MultipleVariantIterator& gamgee::MultipleVariantIterator::operator= ( const MultipleVariantIterator &  other )

delete
