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( $value)
 

Invokes parsing of a header's value into header 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.

Methods
protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::advanceToNextToken(Iterator $tokens, $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.

protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::getAllConsumers()
 

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.

protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::getAllTokenSeparators()
 

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

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

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.

protected getPartForToken( $token, $isLiteral)
 

Returns null for whitespace, and LiteralPart for anything else.

protected getSubConsumers()
 

Returns the following as sub-consumers:

  • {@see CommentConsumer}
  • {@see QuotedStringConsumer}
  • {@see IdConsumer}
protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::getTokenParts(Iterator $tokens)
 

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.

protected getTokenSeparators()
 

Returns '\s+' as a whitespace separator.

protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::getTokenSplitPattern()
 

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.

protected isEndToken( $token)
 

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

protected isStartToken( $token)
 

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

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

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.

protected processParts(array $parts)
 

Overridden to filter out any found CommentPart objects.

protected ZBateson\MailMimeParser\Header\Consumer\AbstractConsumer::splitRawValue( $rawValue)
 

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.

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.
