ParameterConsumer extends GenericConsumer
Reads headers separated into parameters consisting of a main value, and subsequent name/value pairs - for example text/html; charset=utf-8.
A ParameterConsumer's parts are separated by a semi-colon. Its name/value pairs are separated with an '=' character.
Parts may be mime-encoded entities. Additionally, a value can be quoted and comments may exist.

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

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>

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()
Creates and returns a \ZBateson\MailMimeParser\Header\Part\Token out of the passed string token and returns it, unless the token is an escaped literal, in which case a LiteralPart is returned.
protected
getPartForToken(string $token, bool $isLiteral) : HeaderPart
Parameters
- $token : string
- $isLiteral : bool
Return values
HeaderPart —getSubConsumers()
Called during construction to set up the list of sub-consumers that will take control from this consumer should a token match a sub-consumer's start token.
protected
abstract getSubConsumers() : array<string|int, AbstractConsumer>
Return values
array<string|int, AbstractConsumer> —the array of 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

array<string|int, HeaderPart>|array<string|int, mixed> —getTokenSeparators()
Returns semi-colon and equals char as token separators.
protected
getTokenSeparators() : array<string|int, string>
Return values
array<string|int, string> —getTokenSplitPattern()
Overridden to use a specialized regex for finding mime-encoded parts (RFC 2047).
protected
getTokenSplitPattern() : string
Some implementations seem to place mime-encoded parts within quoted parameters, and split the mime-encoded parts across multiple split parameters. The specialized regex doesn't allow double quotes inside a mime encoded part, so it can be "continued" in another parameter.
Return values
string —the regex pattern
isEndToken()
Returns true if the passed string token marks the end marker for the current consumer.
protected
abstract isEndToken(string $token) : bool
Parameters
- $token : string
-
the current token
Return values
bool —isStartToken()
Returns true if the passed string token marks the beginning marker for the current consumer.
protected
abstract 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 \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()
Post processing involves creating Part\LiteralPart or Part\ParameterPart objects out of created Token and LiteralParts.
protected
processParts(array<string|int, HeaderPart> $parts) : array<string|int, HeaderPart>|array<string|int, mixed>
Parameters
- $parts : array<string|int, HeaderPart>

array<string|int, HeaderPart>|array<string|int, mixed> —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
addSpaces()
Checks if the passed space part should be added to the returned parts and adds it.

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

array<string|int, HeaderPart>|array<string|int, mixed> —getPartFor()
Instantiates and returns either a MimeLiteralPart if $strName is empty, a SplitParameterToken if the parameter is a split parameter and is the first in a series, null if it's a split parameter but is not the first part in its series, or a ParameterPart is returned otherwise.
