QuotedStringConsumer extends GenericConsumer
Represents a quoted part of a header value starting at a single quote, and ending at the next single 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.

QuotedStringConsumer doesn't have any sub-consumers. This method returns an empty array.
public
getSubConsumers() : array<string|int, mixed>
Return values
array<string|int, 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 —filterIgnoredSpaces()
Filters out ignorable spaces between parts in the passed array.
protected
filterIgnoredSpaces(array<string|int, HeaderPart> $parts) : array<string|int, HeaderPart>
Spaces with parts on either side of it that specify they can be ignored are filtered out. filterIgnoredSpaces is called from within processParts, and if needed by an implementing class that overrides processParts, must be specifically called.
Parameters

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> —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

not used - everything in a quoted string is a literal
Return values
LiteralPart —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
array<string|int, HeaderPart>|array<string|int, mixed> —getTokenSeparators()
Returns a single regex pattern for a double quote.
protected
getTokenSeparators() : array<string|int, string>

array<string|int, string> —getTokenSplitPattern()
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.
protected
getTokenSplitPattern() : string

string —the regex pattern
isEndToken()
Returns true if the token is a double quote.

Return values
bool —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()
Performs any final processing on the array of parsed parts before returning it to the consumer client.
protected
processParts(array<string|int, HeaderPart> $parts) : array<string|int, HeaderPart>
The default implementation simply returns the passed array after filtering out null/empty parts.
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

array<string|int, mixed> —the array of tokens
addSpaces()
