QuotedStringConsumer extends GenericConsumer
in package

Represents a quoted part of a header value starting at a double quote, and ending at the next double quote.

A quoted-pair part in a header is a literal. There are no sub-consumers for it and a Part\LiteralPart is returned.

Newline characters (CR and LF) are stripped entirely from the quoted part. This is based on the example at:

https://tools.ietf.org/html/rfc822#section-3.1.1

And https://www.w3.org/Protocols/rfc1341/7_2_Multipart.html in section 7.2.1 splitting the boundary.

Properties

Methods

__invoke()

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

public __invoke(string $value) : array<string|int, IHeaderPart>
Parameters
$value : string

the raw header value

Return values
array<string|int, IHeaderPart>

the array of parsed parts

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) : static

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

The token iterator.

$isStartToken : bool

true for the start token.

Return values
static

filterIgnoredSpaces()

No ignored spaces in a quoted part. Returns the passed $parts param as-is.

protected filterIgnoredSpaces(array<string|int, mixed> $parts) : array<string|int, HeaderPart>
Parameters
$parts : array<string|int, mixed>
Return values
array<string|int, HeaderPart>

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 a LiteralPart and returns it.

protected getPartForToken(string $token, bool $isLiteral) : IHeaderPart|null
Parameters
$token : string
$isLiteral : bool

not used - everything in a quoted string is a literal

Return values
IHeaderPart|null

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()

Returns a single regex pattern for a double quote.

protected getTokenSeparators() : array<string|int, string>
Return values
array<string|int, string>

getTokenSplitPattern()

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

protected getTokenSplitPattern() : string

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

Return values
string

the regex pattern

isEndToken()

Returns true if the token is a double quote.

protected isEndToken(string $token) : bool
Parameters
$token : string

The current token

Return values
bool

isStartToken()

Returns true if the token is a double quote.

protected isStartToken(string $token) : bool
Parameters
$token : string

The current token

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()

Performs any final processing on the array of parsed parts before returning it to the consumer client.

protected processParts(array<string|int, IHeaderPart$parts) : array<string|int, IHeaderPart>

The default implementation simply returns the passed array after filtering out null/empty parts.

Parameters
$parts : array<string|int, IHeaderPart>

The parsed parts.

Return values
array<string|int, IHeaderPart>

Array of resulting final parts.

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

addSpaces()

Checks if the passed space part should be added to the returned parts and adds it.

private addSpaces(array<string|int, HeaderPart$parts, array<string|int, HeaderPart&$retParts, int $curIndex[, HeaderPart &$spacePart = null ]) : self

Never adds a space if it's the first part, otherwise only add it if either part isn't set to ignore the space

Parameters
$parts : array<string|int, HeaderPart>
$retParts : array<string|int, HeaderPart>
$curIndex : int
$spacePart : HeaderPart = null
Return values
self

addSpaceToRetParts()

Loops over the $parts array from the current position, checks if the space should be added, then adds it to $retParts and returns.

private addSpaceToRetParts(array<string|int, HeaderPart$parts, array<string|int, HeaderPart&$retParts, int $curIndex, HeaderPart &$spacePart, HeaderPart $lastPart) : self
Parameters
$parts : array<string|int, HeaderPart>
$retParts : array<string|int, HeaderPart>
$curIndex : int

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>
