FrozenParameterBag

class FrozenParameterBag extends ParameterBag

Holds read-only parameters.

Methods

__construct(array $parameters = array())

For performance reasons, the constructor assumes that all keys are already lowercased.

clear()

Clears all parameters.

add(array $parameters)

Adds parameters to the service container parameters.

array all()

Gets the service container parameters.

from ParameterBag
mixed get(string $name)

Gets a service container parameter.

from ParameterBag
set(string $name, mixed $value)

Sets a service container parameter.

bool has(string $name)

Returns true if a parameter name is defined.

from ParameterBag
remove(string $name)

Removes a parameter.

resolve()

Replaces parameter placeholders (%name%) by their values for all parameters.

from ParameterBag
resolveValue(mixed $value, array $resolving = array())

Replaces parameter placeholders (%name%) by their values.

from ParameterBag
string resolveString(string $value, array $resolving = array())

Resolves parameters inside a string.

from ParameterBag
isResolved() from ParameterBag
mixed escapeValue(mixed $value)

Escape parameter placeholders %.

from ParameterBag
mixed unescapeValue(mixed $value)

Unescape parameter placeholders %.

from ParameterBag

Details

__construct(array $parameters = array())

For performance reasons, the constructor assumes that all keys are already lowercased.

This is always the case when used internally.

Parameters

array $parameters An array of parameters

clear()

Clears all parameters.

add(array $parameters)

Adds parameters to the service container parameters.

Parameters

array $parameters An array of parameters

array all()

Gets the service container parameters.

Return Value

array An array of parameters

mixed get(string $name)

Gets a service container parameter.

Parameters

string $name The parameter name

Return Value

mixed The parameter value

Exceptions

ParameterNotFoundException if the parameter is not defined

set(string $name, mixed $value)

Sets a service container parameter.

Parameters

string $name The parameter name
mixed $value The parameter value

bool has(string $name)

Returns true if a parameter name is defined.

Parameters

string $name The parameter name

Return Value

bool true if the parameter name is defined, false otherwise

remove(string $name)

Removes a parameter.

Parameters

string $name The parameter name

resolve()

Replaces parameter placeholders (%name%) by their values for all parameters.

resolveValue(mixed $value, array $resolving = array())

Replaces parameter placeholders (%name%) by their values.

Parameters

mixed $value A value
array $resolving An array of keys that are being resolved (used internally to detect circular references)

Exceptions

ParameterNotFoundException if a placeholder references a parameter that does not exist
ParameterCircularReferenceException if a circular reference if detected
RuntimeException when a given parameter has a type problem.

string resolveString(string $value, array $resolving = array())

Resolves parameters inside a string.

Parameters

string $value The string to resolve
array $resolving An array of keys that are being resolved (used internally to detect circular references)

Return Value

string The resolved string

Exceptions

ParameterNotFoundException if a placeholder references a parameter that does not exist
ParameterCircularReferenceException if a circular reference if detected
RuntimeException when a given parameter has a type problem.

isResolved()

mixed escapeValue(mixed $value)

Escape parameter placeholders %.

Parameters

mixed $value

Return Value

mixed

mixed unescapeValue(mixed $value)

Unescape parameter placeholders %.

Parameters

mixed $value

Return Value

mixed
