Symfony\Component\HttpKernel\Config\EnvParametersResource

class EnvParametersResource implements SelfCheckingResourceInterface, Serializable

EnvParametersResource represents resources stored in prefixed environment variables.

Methods

__construct(string $prefix)

Constructor.

string __toString()

Returns a string representation of the Resource.

array getResource()
bool isFresh(int $timestamp)

Returns true if the resource has not been updated since the given timestamp.

serialize()
unserialize($serialized)

Details

public __construct(string $prefix)

Constructor.

Parameters

string $prefix

public string __toString()

Returns a string representation of the Resource.

This method is necessary to allow for resource de-duplication, for example by means of array_unique(). The string returned need not have a particular meaning, but has to be identical for different ResourceInterface instances referring to the same resource; and it should be unlikely to collide with that of other, unrelated resource instances.

Return Value

string A string representation unique to the underlying Resource

public array getResource()

Return Value

array An array with two keys: 'prefix' for the prefix used and 'variables' containing all the variables watched by this resource

public bool isFresh(int $timestamp)

Returns true if the resource has not been updated since the given timestamp.

Parameters

int $timestamp The last time the resource was loaded

Return Value

bool True if the resource has not been updated, false otherwise

public serialize()

public unserialize($serialized)

Parameters

$serialized
