Constructor Details

BundleResourceBase

public BundleResourceBase(String displayName,
 String contentType,
 String format)

Base constructor for creating a new bundle resource.

Parameters:

displayName - A user-recognizable name for this resource. Used for error messages. May not be null or 0 length.

contentType - The content type for this resource. Can be any string, but it must be unique within a given bundle. May not be null or zero length.

format - The (optional) format for this resource. Can be any string, i.e, "BAM" for a resource with content type "READS". Predefined format strings are defined in BundleResourceType.

Method Details

getDisplayName

public String getDisplayName()

Description copied from interface: BundleResource

Get the display name for this resource.

Specified by:

getDisplayName in interface BundleResource

Returns:

the display name for this resource

getContentType

public String getContentType()

Description copied from interface: BundleResource

Get the content type for this resource.

Specified by:

getContentType in interface BundleResource

Returns:

a string representing name of the content type for this resource

getFileFormat

public Optional<String> getFileFormat()

Description copied from interface: BundleResource

Get the file format for this resource.

Specified by:

getFileFormat in interface BundleResource

Returns:

the file format for this resource, or Optional.empty if not present

getIOPath

public Optional<IOPath> getIOPath()

Description copied from interface: BundleResource

Get the IOPath backing this resource, or Optional.empty.

Specified by:

getIOPath in interface BundleResource

Returns:

the IOPath backing this resource, or Optional.empty if the resource has no backing IOPath

getInputStream

public Optional<InputStream> getInputStream()

Description copied from interface: BundleResource

Get an InputStream for this resource, or Optional.empty.

Specified by:

getInputStream in interface BundleResource

Returns:

an InputStream for this resource, or Optional.empty if BundleResource.hasInputType() is false for this resource. The stream returned by this method may be buffered or use read-ahead, which may not be suitable for applications such as index creation that need control over the position of the underlying stream.

getOutputStream

public Optional<OutputStream> getOutputStream()

Description copied from interface: BundleResource

Get an OutputStream for this resource, or Optional.empty.

Specified by:

getOutputStream in interface BundleResource

Returns:

an OutputStream for this resource, or Optional.empty if BundleResource.hasOutputType() is false for this resource

getSeekableStream

public Optional<SeekableStream> getSeekableStream()

Description copied from interface: BundleResource

Get a SeekableStream for this resource, or Optional.empty.

Specified by:

getSeekableStream in interface BundleResource

Returns:

an SeekableStream for this resource, or Optional.empty if this is not an input type (see BundleResource.hasInputType()), or is an input type for which no SeekableStream can be obtained (see BundleResource.hasSeekableStream()).

hasSeekableStream

public boolean hasSeekableStream()

Description copied from interface: BundleResource

Returns true if this resource can be rendered as a SeekableStream.

Specified by:

hasSeekableStream in interface BundleResource

Returns:

true if this resource can be rendered as a SeekableStream (see BundleResource.getSeekableStream())

hasInputType

public boolean hasInputType()

Description copied from interface: BundleResource

Return true if is this resource is backed by a type that can be used for input. Some resource types, such as InputStreamResource, can be used for input but not for output (see BundleResource.hasOutputType(). Others, such as OutputStreamResource, can be used for output but not for input. Some resource types may be suitable for both (for example see IOPathResource).

The determination is based only on the type of the resource, and does not imply a guarantee about whether the resource type is actually readable.

Specified by:

hasInputType in interface BundleResource

Returns:

true if the type of this resource makes it suitable for use as a source of input.

hasOutputType

public boolean hasOutputType()

Description copied from interface: BundleResource

Return true if this resource is backed by a type that can be used for output. Some resource types, such as InputStreamResource, can be used for input but not for output (see BundleResource.hasOutputType(). Others, such as OutputStreamResource, can be used for output but not for input. Some resource types may be suitable for both (for example see IOPathResource).

The determination is based only on the type of the resource, and does not imply a guarantee about whether the resource is actually writeable.

Specified by:

hasOutputType in interface BundleResource

Returns:

true if the type of this resource makes it suitable for use as target for output.

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
