class Vector::BLF::ObjectQueue\< T \>"Thread-safe queue for **ObjectHeaderBase**

## Member Function Documentation

### template\<typename T\> void Vector::BLF::ObjectQueue\< T \>::abort ()

Stop further operations. Return from waiting reads.

### template\<typename T\> bool Vector::BLF::ObjectQueue\< T \>::eof () const

Check whether eofbit is set.

**Returns**

true if eofbit is set

### template\<typename T\> bool Vector::BLF::ObjectQueue\< T \>::good () const

Check whether state of stream is good.

**Returns**

true if no error flags are set

### template\<typename T\> T \* Vector::BLF::ObjectQueue\< T \>::read ()

Get access to front of queue.

**Returns**

object (or nullptr if empty)

### template\<typename T\> void Vector::BLF::ObjectQueue\< T \>::setBufferSize (uint32\_t bufferSize)

Sets the maximum file size. Write operations block, if the size is reached.

**Parameters**

*bufferSize* maximum file size

### template\<typename T\> void Vector::BLF::ObjectQueue\< T \>::setFileSize (uint32\_t fileSize)

Set file size resp. end-of-file position.

**Parameters**

*fileSize* file size

### template\<typename T\> uint32\_t Vector::BLF::ObjectQueue\< T \>::tellg () const

Get position in input sequence.

**Returns**

Read position

### template\<typename T\> uint32\_t Vector::BLF::ObjectQueue\< T \>::tellp () const

Get position in output sequence.

**Returns**

Write position

### template\<typename T\> void Vector::BLF::ObjectQueue\< T \>::write (T \* obj)

Enqueue an object to end of queue.

nullptr can be pushed to indicate eof.

**Parameters**

*obj* object
