ParameterNameValueConsumerService
extends AbstractGenericConsumerService
in package
Parses an individual part of a parameter header.
'isStartToken' always returns true, so control is taken from ParameterConsumerService always, and returned when a ';' is encountered (and so processes a single part and returns it, then gets control back).0
If an '=' is encountered, the ParameterValueConsumerService sub-consumer takes control and parses the value of a parameter.
If no '=' is encountered, it's assumed to be a single value element, which should be the first part of a parameter header, e.g. 'text/html' in Content-Type: text/html; charset=utf-8

- $quotedStringConsumerService : QuotedStringConsumerService
Return values
mixed —__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 —getAllConsumers()
Returns this consumer and all unique sub consumers.
protected
getAllConsumers() : array<string|int, AbstractConsumerService>
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, AbstractConsumerService> —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<string|int, string> $tokens) : array<string|int, IHeaderPart>
If no sub-consumer is responsible for the current token, calls AbstractConsumerService::getPartForToken() and returns it in an array.
Parameters
- $tokens : Iterator<string|int, string>
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.
getTokenParts()
Returns an array of IHeaderPart for the current token on the iterator.
protected
getTokenParts(Iterator<string|int, string> $tokens) : array<string|int, IHeaderPart>
If the current token is a start token from a sub-consumer, the sub- consumer's AbstractConsumerService::parseTokensIntoParts() method is called.
Parameters
- $tokens : Iterator<string|int, string>
-
The token iterator.
Return values
array<string|int, IHeaderPart> —getTokenSeparators()
Returns semi-colon as a token separator, in addition to parent token separators.
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 AbstractConsumerService::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 ';' char.
protected
isEndToken(string $token) : bool
Parameters
- $token : string
-
The current token
Return values
bool —isStartToken()
Always returns true to grab control from its parent ParameterConsumerService.
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<string|int, string> $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 AbstractConsumerService::processParts for any final processing if there are any parts.
Parameters
- $tokens : Iterator<string|int, string>
-
An iterator over a string of tokens
Return values
array<string|int, IHeaderPart> —An array of parsed parts
processParts()
Creates either a ContainerPart if an '=' wasn't encountered, indicating this to be the main 'value' part of a header (or a malformed part of a parameter header), or a ParameterPart if the last IHeaderPart in the passed $parts array is already a ContainerPart (indicating it was parsed in ParameterValueConsumerService.)
protected
processParts(array<string|int, IHeaderPart> $parts) : array<string|int, IHeaderPart>
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, string>
The method calls preg_split using AbstractConsumerService::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, string> —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
