Data (Hazelcast Root 3.6.5 API)

All Known Implementing Classes:

HeapData, Packet
```
public interface Data
```
Data is basic unit of serialization. It stores binary form of an object serialized by SerializationService.toData(Object).

Method Summary

Methods
Modifier and Type	Method and Description
`int`	`dataSize()` Returns size of internal binary data in bytes
`int`	`getHeapCost()` Returns approximate heap cost of this Data object in bytes.
`int`	`getPartitionHash()` Returns partition hash calculated for serialized object.
`int`	`getType()` Returns serialization type of binary form.
`long`	`hash64()` Returns 64-bit hash code for this Data object.
`boolean`	`hasPartitionHash()` Returns true if Data has partition hash, false otherwise.
`boolean`	`isPortable()` Returns true if this Data is created from a `Portable` object, false otherwise.
`byte[]`	`toByteArray()` Returns byte array representation of internal binary format.
`int`	`totalSize()` Returns the total size of Data in bytes

- Method Detail
  - toByteArray
```
byte[] toByteArray()
```
    Returns byte array representation of internal binary format.
    
    Returns:
    binary data
  - getType
```
int getType()
```
    Returns serialization type of binary form. It's defined by Serializer.getTypeId()
    
    Returns:
    serializer type id
  - totalSize
```
int totalSize()
```
    Returns the total size of Data in bytes
    
    Returns:
    total size
  - dataSize
```
int dataSize()
```
    Returns size of internal binary data in bytes
    
    Returns:
    internal data size
  - getHeapCost
```
int getHeapCost()
```
    Returns approximate heap cost of this Data object in bytes.
    
    Returns:
    approximate heap cost
  - getPartitionHash
```
int getPartitionHash()
```
    Returns partition hash calculated for serialized object. Partition hash is used to determine partition of a Data and is calculated using PartitioningStrategy during serialization.
    If partition hash is not set then standard hashCode() is used.
    
    Returns:
    partition hash

    PartitionAware, PartitioningStrategy, SerializationService.toData(Object, com.hazelcast.core.PartitioningStrategy)
  - hasPartitionHash
```
boolean hasPartitionHash()
```
    Returns true if Data has partition hash, false otherwise.
    
    Returns:
    true if Data has partition hash, false otherwise.
  - hash64
```
long hash64()
```
    Returns 64-bit hash code for this Data object.
    
    Returns:
    64-bit hash code
  - isPortable
```
boolean isPortable()
```
    Returns true if this Data is created from a Portable object, false otherwise.
    
    Returns:
    true if source object is Portable, false otherwise.
