AttributeMatch

FinalYes

Single comparison source for interpreted and compiled paths; MISSING never matches.

Constants

MISSING : mixed = "\x00__flow_telemetry_missing__\x00": Sentinel for an absent path segment; null values are never stored on Attributes.

Methods

contains() : bool
endsWith() : bool
equal() : bool
greaterThan() : bool
greaterThanEqual() : bool
lessThan() : bool
lessThanEqual() : bool
notEqual() : bool
regexp() : bool
resolve() : mixed: Resolve a nested attribute path, descending into array values.
startsWith() : bool
stringForm() : string|null: String form of an AnyValue for the substring/regexp modes.

    public
            static        contains(string|null $value, string $needle, bool $caseSensitive) : bool

Parameters

$value : string|null
$needle : string
$caseSensitive : bool

Return values

bool

endsWith()


    public
            static        endsWith(string|null $value, string $needle, bool $caseSensitive) : bool

Parameters

$value : string|null

equal()


    public
            static        equal(mixed $value, bool|float|int|string|DateTimeInterface $expected) : bool

Parameters

$expected : bool|float|int|string|DateTimeInterface

Return values

greaterThan()


    public
            static        greaterThan(mixed $value, bool|float|int|string|DateTimeInterface $expected) : bool

Parameters

$value : mixed
$expected : bool|float|int|string|DateTimeInterface

greaterThanEqual()


    public
            static        greaterThanEqual(mixed $value, bool|float|int|string|DateTimeInterface $expected) : bool

Parameters

$value : mixed
$expected : bool|float|int|string|DateTimeInterface

Return values

bool

lessThan()


    public
            static        lessThan(mixed $value, bool|float|int|string|DateTimeInterface $expected) : bool

Parameters

$value : mixed
$expected : bool|float|int|string|DateTimeInterface

Return values

lessThanEqual()


    public
            static        lessThanEqual(mixed $value, bool|float|int|string|DateTimeInterface $expected) : bool

Parameters

$value : mixed
$expected : bool|float|int|string|DateTimeInterface

Return values

bool

notEqual()


    public
            static        notEqual(mixed $value, bool|float|int|string|DateTimeInterface $expected) : bool

Parameters

$value : mixed
$expected : bool|float|int|string|DateTimeInterface

Return values

bool

regexp()


    public
            static        regexp(string|null $value, string $pattern) : bool

Parameters

$value : string|null
$pattern : string

Return values

bool

resolve()

Resolve a nested attribute path, descending into array values.


    public
            static        resolve(Attributes $attributes, array<int, string> $segments) : mixed

Parameters

$attributes : Attributes
$segments : array<int, string>

Return values

mixed —

the OpenTelemetry AnyValue at the path, or self::MISSING when any segment is absent

startsWith()


    public
            static        startsWith(string|null $value, string $needle, bool $caseSensitive) : bool

Parameters

$value : string|null
$needle : string
$caseSensitive : bool

Return values

bool

stringForm()

String form of an AnyValue for the substring/regexp modes.


    public
            static        stringForm(mixed $value) : string|null

Mirrors the scalar handling of Attributes::normalize(): DateTime is formatted as ISO 8601 and booleans as "true"/"false". Arrays, throwables and the self::MISSING sentinel have no string form and return null, which the substring/regexp modes treat as "no match".

Parameters

$value : mixed

Return values

string|null
