_reflectionCache() protected 

_reflectionCache()

Gets the methods implemented by this behavior

Uses the implementedEvents() method to exclude callback methods. Methods starting with _ will be ignored, as will methods declared on Cake\ORM\Behavior

Returns

array

Throws

ReflectionException

_resolveMethodAliases() protected 

_resolveMethodAliases(string $key, array $defaults, array $config)

Removes aliased methods that would otherwise be duplicated by userland configuration.

Parameters

string $key

The key to filter.

array $defaults

The default method mappings.

array $config

The customized method mappings.

Returns

array

A de-duped list of config data.

_updateField() protected 

_updateField(\Cake\Datasource\EntityInterface $entity, string $field, bool $refreshTimestamp)

Update a field, if it hasn't been updated already

Parameters

\Cake\Datasource\EntityInterface $entity

Entity instance.

string $field

Field name

bool $refreshTimestamp

Whether to refresh timestamp.

configShallow() public 

configShallow(mixed $key, mixed $value)

Merge provided config with existing config. Unlike config() which does a recursive merge for nested keys, this method does a simple merge.

Setting a specific value:

$this->configShallow('key', $value);

Setting a nested value:

$this->configShallow('some.nested.key', $value);

Updating multiple config settings at the same time:

$this->configShallow(['one' => 'value', 'another' => 'value']);

Parameters

string|array $key

The key to set, or a complete array of configs.

mixed|null $value optional

The value to set.

Returns

$this

getConfig() public 

getConfig(?string $key, mixed $default)

Returns the config.

Usage

Reading the whole config:

$this->getConfig();

Reading a specific value:

$this->getConfig('key');

Reading a nested value:

$this->getConfig('some.nested.key');

Reading with default value:

$this->getConfig('some-key', 'default-value');

Parameters

string|null $key optional

The key to get or null for the whole config.

mixed $default optional

The return value when the key does not exist.

Returns

mixed

Configuration data at the named key or null if the key does not exist.

getConfigOrFail() public 

getConfigOrFail(string $key)

Returns the config for this specific key.

The config value for this key must exist, it can never be null.

Parameters

string $key

The key to get.

Returns

mixed

Configuration data at the named key

Throws

InvalidArgumentException

getTable() public 

getTable()

Get the table instance this behavior is bound to.

Returns

\Cake\ORM\Table

The bound table instance.

handleEvent() public 

handleEvent(\Cake\Event\EventInterface $event, \Cake\Datasource\EntityInterface $entity)

There is only one event handler, it can be configured to be called for any event

Parameters

\Cake\Event\EventInterface $event

Event instance.

\Cake\Datasource\EntityInterface $entity

Entity instance.

Returns

true

Returns true irrespective of the behavior logic, the save will not be prevented.

Throws

UnexpectedValueException
if a field's when value is misdefined
UnexpectedValueException
When the value for an event is not 'always', 'new' or 'existing'

implementedEvents() public 

implementedEvents()

implementedEvents

The implemented events of this behavior depend on configuration

Returns

array

implementedFinders() public 

implementedFinders()

implementedFinders

Provides an alias->methodname map of which finders a behavior implements. Example:

[
   'this' => 'findThis',
   'alias' => 'findMethodName'
 ]

With the above example, a call to $table->find('this') will call $behavior->findThis() and a call to $table->find('alias') will call $behavior->findMethodName()

It is recommended, though not required, to define implementedFinders in the config property of child classes such that it is not necessary to use reflections to derive the available method list. See core behaviors for examples

Returns

array

Throws

ReflectionException

implementedMethods() public 

implementedMethods()

implementedMethods

Provides an alias->methodname map of which methods a behavior implements. Example:

[
   'method' => 'method',
   'aliasedMethod' => 'somethingElse'
 ]

With the above example, a call to $table->method() will call $behavior->method() and a call to $table->aliasedMethod() will call $behavior->somethingElse()

It is recommended, though not required, to define implementedFinders in the config property of child classes such that it is not necessary to use reflections to derive the available method list. See core behaviors for examples

Returns

array

Throws

ReflectionException

initialize() public 

initialize(array $config)

Initialize hook

If events are specified - do not merge them with existing events, overwrite the events to listen on

Parameters

array $config

The config for this behavior.

setConfig() public 

setConfig(mixed $key, mixed $value, mixed $merge)

Sets the config.

Usage

Setting a specific value:

$this->setConfig('key', $value);

Setting a nested value:

$this->setConfig('some.nested.key', $value);

Updating multiple config settings at the same time:

$this->setConfig(['one' => 'value', 'another' => 'value']);

Parameters

string|array $key

The key to set, or a complete array of configs.

mixed|null $value optional

The value to set.

bool $merge optional

Whether to recursively merge or overwrite existing config, defaults to true.

Returns

$this

Throws

Cake\Core\Exception\Exception
When trying to set a key that is invalid.

timestamp() public 

timestamp(?\DateTimeInterface $ts, bool $refreshTimestamp)

Get or set the timestamp to be used

Set the timestamp to the given DateTime object, or if not passed a new DateTime object If an explicit date time is passed, the config option refreshTimestamp is automatically set to false.

Parameters

\DateTimeInterface|null $ts optional

Timestamp

bool $refreshTimestamp optional

If true timestamp is refreshed.

Returns

\Cake\I18n\Time

touch() public 

touch(\Cake\Datasource\EntityInterface $entity, string $eventName)

Touch an entity

Bumps timestamp fields for an entity. For any fields configured to be updated "always" or "existing", update the timestamp value. This method will overwrite any pre-existing value.

Parameters

\Cake\Datasource\EntityInterface $entity

Entity instance.

string $eventName optional

Event name.

Returns

bool

true if a field is updated, false if no action performed

verifyConfig() public 

verifyConfig()

verifyConfig

Checks that implemented keys contain values pointing at callable.

Throws

Cake\Core\Exception\Exception
if config are invalid

Property Detail

$_config protected

Runtime config

Type

array

$_configInitialized protected

Whether the config property has already been configured with defaults

Type

bool

$_defaultConfig protected

Default config

These are merged with user-provided config when the behavior is used.

events - an event-name keyed array of which fields to update, and when, for a given event possible values for when a field will be updated are "always", "new" or "existing", to set the field value always, only when a new record or only when an existing record.

refreshTimestamp - if true (the default) the timestamp used will be the current time when the code is executed, to set to an explicit date time value - set refreshTimetamp to false and call setTimestamp() on the behavior class before use.

Type

array

$_reflectionCache protected static

Reflection method cache for behaviors.

Stores the reflected method + finder methods per class. This prevents reflecting the same class multiple times in a single process.

Type

array

$_table protected

Table instance.

Type

\Cake\ORM\Table

$_ts protected

Current timestamp

Type
