## Detailed Description

LOG\_CONTAINER.

## Member Function Documentation

### uint32\_t Vector::BLF::LogContainer::calculateObjectSize () const \[override\], \[virtual\]

Calculates the objectSize

**Returns**

object size

Reimplemented from **Vector::BLF::ObjectHeaderBase**.

### void Vector::BLF::LogContainer::compress (const uint16\_t compressionMethod, const int compressionLevel) \[virtual\]

compress data

**Parameters**

**compressionMethod compression method** \
 *compressionLevel* **compression level (different for each method)**

### uint16\_t Vector::BLF::LogContainer::internalHeaderSize () const

**internalHeaderSize returns the size of all headers.**

**Note**

**Not to be mixed with headerSize, which only takes ObjectHeaderBase headers into account.**

**Returns**

**Size of all headers.**

### void Vector::BLF::LogContainer::read (AbstractFile & is) \[override\], \[virtual\]

**Read the data of this object**

**Parameters**

*is* **input stream**

**Reimplemented from Vector::BLF::ObjectHeaderBase.**

### void Vector::BLF::LogContainer::uncompress () \[virtual\]

**uncompress data**

### void Vector::BLF::LogContainer::write (AbstractFile & os) \[override\], \[virtual\]

**Write the data of this object**

**Parameters**

*os* **output stream**

**Reimplemented from Vector::BLF::ObjectHeaderBase.**
