### Class: \Somnambulist\Components\ReadModels\ModelExporter
Visibility Function
public __construct(\Somnambulist\Components\ReadModels\Model $model, array $attributes=array(), array $relationships=array()) : void
public attributes(mixed $attributes) : \Somnambulist\Components\ReadModels\ModelExporter
Export only the specified attributes; if empty will export all attributes
public include(mixed $relationship) : \Somnambulist\Components\ReadModels\ModelExporter
Export with the specified relationships; if empty will NOT export any relationships
public toArray() : void
public toJson(\int $options) : void

This class implements \Somnambulist\Components\Collection\Contracts\Jsonable

### Class: \Somnambulist\Components\ReadModels\PaginatorAdapter
Visibility Function
public __construct(\Somnambulist\Components\ReadModels\ModelBuilder $queryBuilder) : void
public getNbResults() : mixed
public getSlice(mixed $offset, mixed $length) : mixed

This class implements \Pagerfanta\Adapter\AdapterInterface

### Class: \Somnambulist\Components\ReadModels\Model (abstract)
Visibility Function
public __construct(array $attributes=array()) : void
public __toString() : void
public export() : void
public static find(string $id) : \Somnambulist\Components\ReadModels\Model/null
public static findOrFail(string $id) : \Somnambulist\Components\ReadModels\Model
public getAttribute(\string $name) : mixed/null
Get the requested attribute or relationship If a mutator is defined (getXxxxAttribute method), the attribute will be passed through that first. If the attribute does not exist a virtual accessor will be checked and return if there is one. Finally, if the relationship exists and has not been loaded, it will be at this point.
public getAttributes() : mixed
public getCollection(array $models=array()) : mixed
public getExternalPrimaryKey() : mixed/null
Could return an object e.g. Uuid or string, depending on casting
public getOwningKey() : mixed
Gets the owning side of the relationships key name
public getPrimaryKey() : mixed/null
Could return an object e.g. Uuid, Identity, depending on casting
public getRelationship(\string $method) : \Somnambulist\Components\ReadModels\Relationships\AbstractRelationship
Returns the relationship definition defined by the method name E.g. a User model hasMany Roles, the method would be "roles()".
public static include(mixed $relations) : \Somnambulist\Components\ReadModels\ModelBuilder
Eager load the specified relationships on this model Allows dot notation to load related.related objects.
public jsonSerialize() : void
public meta() : void
public new(array $attributes=array()) : void
public newQuery() : void
public static query() : \Somnambulist\Components\ReadModels\ModelBuilder
Starts a new query builder process without any constraints
public setRelationshipValue(\string $method, \object $related) : void
public toArray() : void
public toJson(\int $options) : void
protected belongsTo(\string $class, \string $foreignKey=null, \string $ownerKey=null, \string $relation=null, \bool $nullOnNotFound=true) : \Somnambulist\Components\ReadModels\Relationships\BelongsTo
Define an inverse one-to-one or many relationship The table in this case will be the owning side of the relationship i.e. the originator of the foreign key on the specified class. For example: a User has many Addresses, the address table has a key: user_id linking the address to the user. This relationship finds the user from the users table where the users.id = user_addresses.user_id. This will only associate a single model as the inverse side, nor will it update the owner with this models association.
protected belongsToMany(\string $class, \string $table, \string $sourceColumnName=null, \string $targetColumnName=null, \string $sourceKey=null, \string $targetKey=null) : \Somnambulist\Components\ReadModels\Relationships\BelongsToMany
Define a new many to many relationship The table is the joining table between the source and the target. The source is the object at the left hand side of the relationship, the target is on the right. For example: User -> Roles through a user_roles table, with user_id, role_id as columns. The relationship would be defined as a User has Roles so the source is user_id and the target is role_id. The table name must be provided and will not be guessed.
protected hasMany(\string $class, \string $foreignKey=null, \string $parentKey=null, \string $indexBy=null) : \Somnambulist\Components\ReadModels\Relationships\HasOneToMany
Define a one to many relationship Here, the parent has many children, so a User can have many addresses. The foreign key is the name of the parents key in the child's table. local key is the child's primary key. indexBy allows a column on the child to be used as the key in the returned collection. Note: if this is specified, then there can be only a single instance of that key returned. This would usually be used on related objects with a type where, the parent can only have one of each type e.g.: a contact has a "type" field for: home, office, cell etc.
protected hasOne(\string $class, \string $foreignKey=null, \string $parentKey=null, \bool $nullOnNotFound=true) : \Somnambulist\Components\ReadModels\Relationships\HasOne
Defines a one to one relationship Here the parent has only one child and the child only has that parent. If multiple records end up being stored, then only the first will be loaded.
