Описание методов

chunk() защищенный Метод

Pulls data directly from file descriptor by given length.
protected chunk ( integer $size = 1 ) : string
$size integer - Default 1
Результат string - Binary safe string.

encodeFromBlob() публичный Метод

This method will copy the given blob to memory descriptor. There's better ways to do this.
public encodeFromBlob ( string $blob ) : string
$blob string - Binary safe string
Результат string

encodeFromFile() публичный Метод

Parse binary file & converts WKB to google encoded string.
public encodeFromFile ( string $filename ) : string
$filename string - The path to the binary file to be encoded.
Результат string - Encoded string

parseWkb() защищенный Метод

Extract points from well-known binary
protected parseWkb ( ) : array
Результат array - Points found in binary

readByte() защищенный Метод

Read single byte from file descriptor.
protected readByte ( ) : integer
Результат integer - Order of byte.

readDouble() защищенный Метод

Read 8 bytes and cast to double. Respects file endianness.
protected readDouble ( ) : double
Результат double

readU32() защищенный Метод

Read 4 bytes and cast to unsigned integer. Respects file endianness.
protected readU32 ( ) : integer
Результат integer
