MongoDB\BSON\Binary::fromVector

(mongodb >=2.2.0)

MongoDB\BSON\Binary::fromVector — Creates a new binary with subtype MongoDB\BSON\Binary::SUBTYPE_VECTOR from the given array and vector type

说明

final public static MongoDB\BSON\Binary::fromVector(array $vector, MongoDB\BSON\VectorType $vectorType): MongoDB\BSON\Binary

参数

vector (array)

An array of values representing the vector data. The type of each value must match the type indicated by the vectorType parameter:

  • for MongoDB\BSON\VectorType::Float32, each value must be a float
  • for MongoDB\BSON\VectorType::Int8, each value must be an 8-bit int, i.e. from -127 to 128
  • for MongoDB\BSON\VectorType::PackedBit, each value must be a bool or 1-bit int, i.e. 0 or 1

vectorType (MongoDB\BSON\VectorType)

The vector data type.

返回值

Returns a new Binary with subtype MongoDB\BSON\Binary::SUBTYPE_VECTOR.
