Methods

__construct(string $data) : void

Object constractor

Parameters

Name	Type	Description
$data	string

_fread(integer $length = 1) : string

Reads $length number of bytes at the current position in the file and advances the file pointer.

Parameters

Name	Type	Description
$length	integer

Returns

Type	Description
string

_fwrite(string $data, integer $length = null) : void

Writes $length number of bytes (all, if $length===null) to the end of the file.

Parameters

Name	Type	Description
$data	string
$length	integer

flush() : boolean

Flush output.

Returns true on success or false on failure.

Returns

Type	Description
boolean

lock(integer $lockType, $nonBlockinLock = false) : boolean

Lock file

Lock type may be a LOCK_SH (shared lock) or a LOCK_EX (exclusive lock)

Parameters

Name	Type	Description
$lockType	integer
$nonBlockinLock

Returns

Type	Description
boolean

readBinary() : string

Reads binary data from the current position in the file and advances the file pointer.

Returns

Type	Description
string

readByte() : integer

Reads a byte from the current position in the file and advances the file pointer.

Returns

Type	Description
integer

readBytes(integer $num) : string

Read num bytes from the current position in the file and advances the file pointer.

Parameters

Name	Type	Description
$num	integer

Returns

Type	Description
string

readInt() : integer

Reads an integer from the current position in the file and advances the file pointer.

Returns

Type	Description
integer

readLong() : integer

Returns a long integer from the current position in the file and advances the file pointer.

Returns

Type	Description
integer

Throws

Exception	Description
\Zend_Search_Lucene_Exception

readLong32Bit() : integer | float

Returns a long integer from the current position in the file, advances the file pointer and return it as float (for 32-bit platforms).

Returns

Type	Description
integer \| float

Throws

Exception	Description
\Zend_Search_Lucene_Exception

readString() : string

Reads a string from the current position in the file and advances the file pointer.

Returns

Type	Description
string

readVInt() : integer

Returns a variable-length integer from the current position in the file and advances the file pointer.

Returns

Type	Description
integer

seek(integer $offset, integer $whence = SEEK_SET) : integer

Sets the file position indicator and advances the file pointer.

The new position, measured in bytes from the beginning of the file, is obtained by adding offset to the position specified by whence, whose values are defined as follows: SEEK_SET - Set position equal to offset bytes. SEEK_CUR - Set position to current location plus offset. SEEK_END - Set position to end-of-file plus offset. (To move to a position before the end-of-file, you need to pass a negative value in offset.) Upon success, returns 0; otherwise, returns -1

Parameters

Name	Type	Description
$offset	integer
$whence	integer

Returns

Type	Description
integer

tell() : integer

Get file position.

Returns

Type	Description
integer

unlock() : void

Unlock file

writeByte(integer $byte) : void

Writes a byte to the end of the file.

Parameters

Name	Type	Description
$byte	integer

writeBytes(string $data, integer $num = null) : void

Writes num bytes of data (all, if $num===null) to the end of the string.

Parameters

Name	Type	Description
$data	string
$num	integer

writeInt(integer $value) : void

Writes an integer to the end of file.

Parameters

Name	Type	Description
$value	integer

writeLong(integer $value) : void

Throws

Exception	Description
\Zend_Search_Lucene_Exception

writeVInt(integer $value) : void

Writes a variable-length integer to the end of file.

Parameters
