Methods

create

Creates a new Record instance.

public create(Node $parentNode, string $key): self

Parameters

Parameter	Type	Description
$parentNode	Node	the parent node of the record
$key	string	the key of the record

read

Reads the record's value from the file.

public read(?int $ptr): mixed

If the value is already in memory, it is returned directly. Otherwise, it seeks to the record's position in the file, reads its length and data, unserializes the data, and returns the value.

Parameters

Parameter	Type	Description
$ptr	int	the pointer to the record in the file. If null, uses the current record's pointer.

write

Writes the record's key and value to the file.

public write(string $key, mixed $value): bool

Serializes the value and writes it to the file. If the record already exists and the new data fits within the allocated space, it updates the record in-place. Otherwise, it appends the new record to the end of the file and updates the pointer.

Parameters

Parameter	Type	Description
$key	string	the key of the record
$value	mixed	the value of the record

moveTo

Moves the record to a new leaf node.

public moveTo(Node $leaf): bool

This method updates the record's parent node and file handle, resets its pointer, writes the record to the new location in the file, and adds the record to the new leaf node.

Parameters

Parameter	Type	Description
$leaf	Node	the new leaf node to move the record to
