Member Function Documentation

isValid()

bool ts::mcast::FluteFile::isValid ( ) const

inlineinherited

Check if the file is valid (for instance is XML content was successfully parsed).

Returns

True if the file is valid. False otherwise.

sessionId()

const FluteSessionId & ts::mcast::FluteFile::sessionId ( ) const

inlineinherited

Get the session id of the file.

Returns

A constant reference to the session in the object.

toi()

uint64_t ts::mcast::FluteFile::toi ( ) const

inlineinherited

Get the Transport Object Identifier (TOI) of the file.

Returns

The Transport Object Identifier.

name()

const UString & ts::mcast::FluteFile::name ( ) const

inlineinherited

Get the name or URN of the file.

Returns

A constant reference to the name in the object.

type()

const UString & ts::mcast::FluteFile::type ( ) const

inlineinherited

Get the base MIME type of the file, excluding qualification such as "charset=utf-8".

Returns

A constant reference to the type string in the object.

fullType()

const UString & ts::mcast::FluteFile::fullType ( ) const

inlineinherited

Get the original full MIME type of the file.

Returns

A constant reference to the type string in the object.

size()

size_t ts::mcast::FluteFile::size ( ) const

inlineinherited

Get the size of the file.

Returns

The size of the file in bytes.

content() [1/2]

ByteBlock & ts::mcast::FluteFile::content ( )

inlineinherited

Access the content of the file (modifiable version).

Returns

A reference to the content of the file.

content() [2/2]

const ByteBlock & ts::mcast::FluteFile::content ( ) const

inlineinherited

Access the content of the file (constant version).

Returns

A constant reference to the content of the file.

contentPointer()

const ByteBlockPtr ts::mcast::FluteFile::contentPointer ( ) const

inlineinherited

Get a shared pointer (std::shared_ptr) to the content of the file. This allow to keep the content for some time, even after the FluteFile object is deleted.

Returns

A shared pointer to the content of the file.

toText()

UString ts::mcast::FluteFile::toText ( ) const

inherited

Get a character string version of the file, if it is a text file.

Returns

A string resulting from the conversion of the file content from UTF-8.

toXML()

UString ts::mcast::FluteFile::toXML ( ) const

inherited

Get an indented XML character string version of the file, if it is a text file.

Returns

A string resulting from the conversion of the file content from UTF-8 and XML reindentation. If the text is not XML, the original text is returned.

parseXML()

bool ts::mcast::FluteFile::parseXML ( xml::Document & xml_doc, const UChar * expected_root = nullptr, bool ignore_namespace = false )

protectedinherited

Parse the document using XML format.

Parameters

[in,out]	xml_doc	XML document to parse.
[in]	expected_root	Expected root name in XML text. Ignored if null or empty.
[in]	ignore_namespace	Specify if XML namespace is ignored by default in this document.

Returns

True on success, false on error.
