DefaultData

public DefaultData(byte[] data)

Method Detail

dataSize

public int dataSize()

Description copied from interface: Data

Returns size of internal binary data in bytes

Specified by:

dataSize in interface Data

Returns:

internal data size

totalSize

public int totalSize()

Description copied from interface: Data

Returns the total size of Data in bytes

Specified by:

totalSize in interface Data

Returns:

total size

getPartitionHash

public int getPartitionHash()

Description copied from interface: Data

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.

Specified by:

getPartitionHash in interface Data

Returns:

partition hash

hasPartitionHash

public boolean hasPartitionHash()

Description copied from interface: Data

Returns true if Data has partition hash, false otherwise.

Specified by:

hasPartitionHash in interface Data

Returns:

true if Data has partition hash, false otherwise.

toByteArray

public byte[] toByteArray()

Description copied from interface: Data

Returns byte array representation of internal binary format.

Specified by:

toByteArray in interface Data

Returns:

binary data

getType

public int getType()

Description copied from interface: Data

Returns serialization type of binary form. It's defined by Serializer.getTypeId()

Specified by:

getType in interface Data

Returns:

serializer type id

getHeapCost

public int getHeapCost()

Description copied from interface: Data

Returns approximate heap cost of this Data object in bytes.

Specified by:

getHeapCost in interface Data

Returns:

approximate heap cost

equals

Specified by:

hash64 in interface Data

Returns:

64-bit hash code

isPortable

public boolean isPortable()

Description copied from interface: Data

Returns true if this Data is created from a Portable object, false otherwise.

Specified by:

isPortable in interface Data

Returns:

true if source object is Portable, false otherwise.
