IdBaseConsumer extends AbstractConsumer
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.

- Returns a list of regular expression markers for this consumer and all sub-consumers by calling 'getTokenSeparators'.
- getConsumerTokenParts() : array<string|int, HeaderPart>|array<string|int, mixed>
- 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 getPartForToken and returns it in an array.
- getPartForToken() : HeaderPart|null
- Returns null for whitespace, and LiteralPart for anything else.
- getSubConsumers() : array<string|int, AbstractConsumer>
- Returns the following as sub-consumers: - \ZBateson\MailMimeParser\Header\Consumer\CommentConsumer - \ZBateson\MailMimeParser\Header\Consumer\QuotedStringConsumer - \ZBateson\MailMimeParser\Header\Consumer\IdConsumer
- getTokenParts() : array<string|int, HeaderPart>|array<string|int, mixed>
- Returns an array of \ZBateson\MailMimeParser\Header\Part\HeaderPart for the current token on the iterator.
- getTokenSeparators() : array<string|int, string>
- Returns '\s+' as a whitespace separator.
- getTokenSplitPattern() : string
- Returns a regex pattern used to split the input header string. The default implementation calls getAllTokenSeparators and implodes the returned array with the regex OR '|' character as its glue.
- isEndToken() : bool
- IdBaseConsumer doesn't have start/end tokens, and so always returns false.
- isStartToken() : bool
- IdBaseConsumer doesn't have start/end tokens, and so always returns false.
- parseTokensIntoParts() : array<string|int, HeaderPart>
- Iterates over the passed token Iterator and returns an array of parsed \ZBateson\MailMimeParser\Header\Part\HeaderPart objects.
- processParts() : array<string|int, HeaderPart>
- Overridden to filter out any found CommentPart objects.
- splitRawValue() : array<string|int, mixed>
- Returns an array of split tokens from the input string.
- parseRawValue() : array<string|int, HeaderPart>
- Called by __invoke to parse the raw header value into header parts.

public
__construct(ConsumerService $consumerService, HeaderPartFactory $partFactory) : mixed
Parameters
- $consumerService : ConsumerService
- $partFactory : HeaderPartFactory
Return values
mixed —__invoke()
Invokes parsing of a header's value into header parts.
public
__invoke(string $value) : array<string|int, HeaderPart>
Parameters
- $value : string
-
the raw header value
Return values
array<string|int, HeaderPart> —the array of parsed parts
getInstance()
Returns the singleton instance for the class.
public
static getInstance(ConsumerService $consumerService, HeaderPartFactory $partFactory) : mixed
Parameters
- $consumerService : ConsumerService
- $partFactory : HeaderPartFactory
Return values
mixed —advanceToNextToken()
Determines if the iterator should be advanced to the next token after reading tokens or finding a start token.
protected
advanceToNextToken(Iterator $tokens, bool $isStartToken) : mixed
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.
Parameters
- $tokens : Iterator
- $isStartToken : bool
Return values
mixed —getAllConsumers()
Returns this consumer and all unique sub consumers.
protected
getAllConsumers() : array<string|int, AbstractConsumer>
Loops into the sub-consumers (and their sub-consumers, etc...) finding all unique consumers, and returns them in an array.
Return values
array<string|int, AbstractConsumer> —getAllTokenSeparators()
Returns a list of regular expression markers for this consumer and all sub-consumers by calling 'getTokenSeparators'.
protected
getAllTokenSeparators() : array<string|int, string>
.
Return values
array<string|int, string> —an array of regular expression markers
getConsumerTokenParts()
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 getPartForToken and returns it in an array.
protected
getConsumerTokenParts(Iterator $tokens) : array<string|int, HeaderPart>|array<string|int, mixed>
Parameters
- $tokens : Iterator
Return values
array<string|int, HeaderPart>|array<string|int, mixed> —getPartForToken()
Returns null for whitespace, and LiteralPart for anything else.
protected
getPartForToken(string $token, bool $isLiteral) : HeaderPart|null
Parameters
- $token : string
-
the token
- $isLiteral : bool
-
set to true if the token represents a literal - e.g. an escaped token
Return values
HeaderPart|null —the constructed header part or null if the token should be ignored
getSubConsumers()
Returns the following as sub-consumers: - \ZBateson\MailMimeParser\Header\Consumer\CommentConsumer - \ZBateson\MailMimeParser\Header\Consumer\QuotedStringConsumer - \ZBateson\MailMimeParser\Header\Consumer\IdConsumer
protected
getSubConsumers() : array<string|int, AbstractConsumer>
Return values
array<string|int, AbstractConsumer> —the sub-consumers
getTokenParts()
Returns an array of \ZBateson\MailMimeParser\Header\Part\HeaderPart for the current token on the iterator.
protected
getTokenParts(Iterator $tokens) : array<string|int, HeaderPart>|array<string|int, mixed>
If the current token is a start token from a sub-consumer, the sub- consumer's parseTokensIntoParts method is called.
Parameters
- $tokens : Iterator
Return values

Returns '\s+' as a whitespace separator.
protected
getTokenSeparators() : array<string|int, string>

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

parseTokensIntoParts()
Iterates over the passed token Iterator and returns an array of parsed \ZBateson\MailMimeParser\Header\Part\HeaderPart objects.
protected
parseTokensIntoParts(Iterator $tokens) : array<string|int, HeaderPart>
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.
Parameters
- $tokens : Iterator
-
an iterator over a string of tokens
Return values
array<string|int, HeaderPart> —an array of parsed parts
processParts()
Overridden to filter out any found CommentPart objects.
protected
processParts(array<string|int, HeaderPart> $parts) : array<string|int, HeaderPart>
Parameters
- $parts : array<string|int, HeaderPart>
Return values
array<string|int, HeaderPart> —splitRawValue()
Returns an array of split tokens from the input string.
protected
splitRawValue(string $rawValue) : array<string|int, mixed>
The method calls preg_split using getTokenSplitPattern. The split array will not contain any empty parts and will contain the markers.
Parameters
- $rawValue : string
-
the raw string
Return values
array<string|int, mixed> —the array of tokens
parseRawValue()
Called by __invoke to parse the raw header value into header parts.
private
parseRawValue(string $value) : array<string|int, HeaderPart>
Calls splitTokens to split the value into token part strings, then calls parseParts to parse the returned array.
Parameters
- $value : string
Return values
array<string|int, HeaderPart> —the array of parsed parts
