Serves as a base-consumer for ID headers (like Message-ID and Content-ID).

IdBaseConsumer handles invalidly-formatted IDs not within '<' and '>'
characters. Processing for validly-formatted IDs are passed on to its
sub-consumer, IdConsumer.

Methods
public ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::__construct(ZBateson\MailMimeParser\Header\Consumer\ConsumerService $consumerService, ZBateson\MailMimeParser\Header\Part\HeaderPartFactory $partFactory)
public ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::__invoke(string $value) : array
 

Invokes parsing of a header's value into header parts.

  • param string $value the raw header value
  • return \ZBateson\MailMimeParser\Header\IHeaderPart[] the array of parsed
    parts
public static ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::getInstance(ZBateson\MailMimeParser\Header\Consumer\ConsumerService $consumerService, ZBateson\MailMimeParser\Header\Part\HeaderPartFactory $partFactory)
 

Returns the singleton instance for the class.

Properties
protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::$consumerService = NULL
 
  • var \ConsumerService used to get consumer instances for sub-consumers.
protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::$partFactory = NULL
 
  • var \HeaderPartFactory used to construct IHeaderPart objects
Methods
protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::advanceToNextToken(Iterator $tokens, bool $isStartToken)
 

Determines if the iterator should be advanced to the next token after
reading tokens or finding a start token.

The default implementation will advance for a start token, but not
advance on the end token of the current consumer, allowing the end token
to be passed up to a higher-level consumer.

  • param \Iterator $tokens The token iterator.
  • param bool $isStartToken true for the start token.
  • return static
protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::getAllConsumers() : array
 

Returns this consumer and all unique sub consumers.

Loops into the sub-consumers (and their sub-consumers, etc...) finding
all unique consumers, and returns them in an array.

  • return \AbstractConsumer[] Array of unique consumers.
protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::getAllTokenSeparators() : array
 

Returns a list of regular expression markers for this consumer and all
sub-consumers by calling getTokenSeparators().

  • return string[] Array of regular expression markers.
protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::getConsumerTokenParts(Iterator $tokens) : array
 

Iterates through this consumer's sub-consumers checking if the current
token triggers a sub-consumer's start token and passes control onto that
sub-consumer's parseTokenIntoParts().

If no sub-consumer is responsible for the current token, calls
{@see \AbstractConsumer::getPartForToken()} and returns it in an array.

  • return \ZBateson\MailMimeParser\Header\IHeaderPart[]
protected getPartForToken(string $token, bool $isLiteral)
 

Returns null for whitespace, and LiteralPart for anything else.

  • param string $token the token
  • param bool $isLiteral set to true if the token represents a literal -
    e.g. an escaped token
  • return \ZBateson\MailMimeParser\Header\IHeaderPart|null the constructed
    header part or null if the token should be ignored
protected getSubConsumers() : array
 

Returns the following as sub-consumers:

  • {@see CommentConsumer}
  • {@see QuotedStringConsumer}
  • {@see IdConsumer}
  • return \AbstractConsumer[] the sub-consumers
protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::getTokenParts(Iterator $tokens) : array
 

Returns an array of IHeaderPart for the current token on the iterator.

If the current token is a start token from a sub-consumer, the sub-
consumer's {@see \AbstractConsumer::parseTokensIntoParts()} method is
called.

  • param \Iterator $tokens The token iterator.
  • return \ZBateson\MailMimeParser\Header\IHeaderPart[]
protected getTokenSeparators() : array
 

Returns '\s+' as a whitespace separator.

  • return string[] an array of regex pattern matchers.
protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::getTokenSplitPattern() : string
 

Returns a regex pattern used to split the input header string.

The default implementation calls
{@see \AbstractConsumer::getAllTokenSeparators()} and implodes the
returned array with the regex OR '|' character as its glue.

  • return string the regex pattern
protected isEndToken(string $token) : bool
 

IdBaseConsumer doesn't have start/end tokens, and so always returns
false.

protected isStartToken(string $token) : bool
 

IdBaseConsumer doesn't have start/end tokens, and so always returns
false.

protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::parseTokensIntoParts(Iterator $tokens) : array
 

Iterates over the passed token Iterator and returns an array of parsed
IHeaderPart objects.

The method checks each token to see if the token matches a sub-consumer's
start token, or if it matches the current consumer's end token to stop
processing.

If a sub-consumer's start token is matched, the sub-consumer is invoked
and its returned parts are merged to the current consumer's header parts.

After all tokens are read and an array of Header\Parts are constructed,
the array is passed to AbstractConsumer::processParts for any final
processing.

  • param \Iterator $tokens An iterator over a string of tokens
  • return \ZBateson\MailMimeParser\Header\IHeaderPart[] An array of
    parsed parts
protected processParts(array $parts) : array
 

Overridden to filter out any found CommentPart objects.

  • param \ZBateson\MailMimeParser\Header\IHeaderPart[] $parts
  • return \ZBateson\MailMimeParser\Header\IHeaderPart[]
protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::splitRawValue( $rawValue) : array
 

Returns an array of split tokens from the input string.

The method calls preg_split using
{@see \AbstractConsumer::getTokenSplitPattern()}. The split array will
not contain any empty parts and will contain the markers.

  • param string $rawValue the raw string
  • return array the array of tokens
Methods
public static ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::getInstance(ZBateson\MailMimeParser\Header\Consumer\ConsumerService $consumerService, ZBateson\MailMimeParser\Header\Part\HeaderPartFactory $partFactory)
 

Returns the singleton instance for the class.
