VCFDecoder

@InternalAPI
public VCFDecoder(Bundle inputBundle,
 AbstractVCFCodec vcfCodec,
 VariantsDecoderOptions variantsDecoderOptions)

InternalAPI Create a new VCF decoder.

Parameters:

inputBundle - the input Bundle to decode

vcfCodec - the AbstractVCFCodec to use for this decoder

variantsDecoderOptions - the VariantsDecoderOptions for this decoder

Method Details

getFileFormat

public final String getFileFormat()

Description copied from interface: HtsDecoder

Get the name of the file format supported by this decoder.The format name defines the underlying format handled by this decoder, and also corresponds to the format of the primary bundle resource that is required when decoding (see BundleResourceType and BundleResource.getFileFormat()).

Specified by:

getFileFormat in interface HtsDecoder<VCFHeader,VariantContext>

Returns:

the name of the underlying file format handled by this decoder

getDisplayName

public final String getDisplayName()

Description copied from interface: HtsDecoder

Get a user-friendly display name for this decoder.

Specified by:

getDisplayName in interface HtsDecoder<VCFHeader,VariantContext>

Returns:

a user-friendly display name for this decoder for use in error and warning messages

getHeader

public VCFHeader getHeader()

Description copied from interface: HtsDecoder

Get the file header for this decoder.

Specified by:

getHeader in interface HtsDecoder<VCFHeader,VariantContext>

Returns:

the file header for this decoder, of type H

iterator

public CloseableIterator<VariantContext> iterator()

Description copied from interface: HtsQuery

Get an iterator of all records in the underlying resource.

Specified by:

iterator in interface HtsQuery<VariantContext>

Specified by:

iterator in interface Iterable<VariantContext>

Returns:

an iterator of all records in the underlying resource

isQueryable

public boolean isQueryable()

Description copied from interface: HtsQuery

Gte true if the underlying resource is queryable.

Specified by:

isQueryable in interface HtsQuery<VariantContext>

Returns:

true if the underlying resource is queryable. this may be true even if the underlying resource returns false for HtsQuery.hasIndex()

hasIndex

public boolean hasIndex()

Description copied from interface: HtsQuery

Return true if the underlying resource has an index.

Specified by:

hasIndex in interface HtsQuery<VariantContext>

Returns:

true if the underlying resource has an index

query

public CloseableIterator<VariantContext> query(List<HtsInterval> intervals,
 HtsQueryRule queryRule)
