ReceivedConsumer
extends AbstractConsumer
in package
Parses a Received header into ReceivedParts, ReceivedDomainParts, a DatePart, and CommentParts.
Parts that don't correspond to any of the above are discarded.

- getConsumerTokenParts() : array<string|int, IHeaderPart>
- 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().

- Constructs and returns an IHeaderPart for the passed string token.
- getSubConsumers() : array<string|int, AbstractConsumer>

- getTokenSplitPattern() : string
- Overridden to exclude the MimeLiteralPart pattern that comes by default in AbstractConsumer.
- isEndToken() : bool
- ReceivedConsumer doesn't have an end token, and so this just returns false.
- isStartToken() : bool
- ReceivedConsumer doesn't start consuming at a specific token, it's the base handler for the Received header, and so this always returns false.

- processParts() : array<string|int, IHeaderPart>
- Overridden to combine all part values into a single string and return it as an array with a single element.

the raw header value
Return values

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()
Overridden to /not/ advance when the end token matches a start token for a sub-consumer.
protected
advanceToNextToken(Iterator $tokens, bool $isStartToken) : static
Parameters
- $tokens : Iterator
-
The token iterator.
- $isStartToken : bool
-
true for the start token.
Return values
static —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> —Array of unique consumers.
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> —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().
protected
getConsumerTokenParts(Iterator $tokens) : array<string|int, IHeaderPart>
If no sub-consumer is responsible for the current token, calls AbstractConsumer::getPartForToken() and returns it in an array.
Parameters
- $tokens : Iterator
Return values
array<string|int, IHeaderPart> —getPartForToken()
Constructs and returns an IHeaderPart for the passed string token.
protected
getPartForToken(string $token, bool $isLiteral) : IHeaderPart|null
If the token should be ignored, the function must return null.
The default created part uses the instance's partFactory->newInstance method.
Parameters
- $token : string
-
the token
- $isLiteral : bool
-
set to true if the token represents a literal - e.g. an escaped token
Return values
IHeaderPart|null —The constructed header part or null if the token should be ignored.
getSubConsumers()
Returns sub-consumers for a received consumer.
protected
getSubConsumers() : array<string|int, AbstractConsumer>
- 2 Received/DomainConsumer instances, with FROM and BY as part names.
- 4 Received/GenericReceivedConsumer instances for VIA, WITH, ID, and FOR part names.
- 1 Received/ReceivedDateConsumer for the date/time stamp.
- 1 CommentConsumer to consume any comments.
Return values
array<string|int, AbstractConsumer> —the sub-consumers
getTokenParts()
Returns an array of IHeaderPart for the current token on the iterator.
protected
getTokenParts(Iterator $tokens) : array<string|int, IHeaderPart>
If the current token is a start token from a sub-consumer, the sub- consumer's AbstractConsumer::parseTokensIntoParts() method is called.
Parameters
- $tokens : Iterator
-
The token iterator.
Return values
array<string|int, IHeaderPart> —getTokenSeparators()
ReceivedConsumer doesn't have any token separators of its own.
protected
getTokenSeparators() : array<string|int, string>
Sub-Consumers will return separators matching 'part' word separators, for example 'from' and 'by', and ';' for date, etc...
Return values
array<string|int, string> —an array of regex pattern matchers
getTokenSplitPattern()
Overridden to exclude the MimeLiteralPart pattern that comes by default in AbstractConsumer.
protected
getTokenSplitPattern() : string
Return values
string —the regex pattern
isEndToken()
ReceivedConsumer doesn't have an end token, and so this just returns false.
protected
isEndToken(string $token) : bool
Parameters
- $token : string
-
The current token
Return values
bool —isStartToken()
ReceivedConsumer doesn't start consuming at a specific token, it's the base handler for the Received header, and so this always returns false.
protected
isStartToken(string $token) : bool
Parameters
- $token : string
-
The current token
Tags
Return values
bool —parseTokensIntoParts()
Iterates over the passed token Iterator and returns an array of parsed IHeaderPart objects.
protected
parseTokensIntoParts(Iterator $tokens) : array<string|int, IHeaderPart>
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, IHeaderPart> —An array of parsed parts
processParts()
Overridden to combine all part values into a single string and return it as an array with a single element.
protected
processParts(array<string|int, IHeaderPart> $parts) : array<string|int, IHeaderPart>
Parameters
- $parts : array<string|int, IHeaderPart>
Return values
array<string|int, IHeaderPart> —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 AbstractConsumer::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()
Parses the raw header value into header parts.
private
parseRawValue(string $value) : array<string|int, IHeaderPart>
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, IHeaderPart> —the array of parsed parts
