Constructor Detail

PortObjectCell

public PortObjectCell(PortObject content)

Constructor for creating port object cell objects.

Parameters:

content - The port object to wrap.

Method Detail

getPreferredValueClass

public static Class<? extends DataValue> getPreferredValueClass()

Returns:

PortObjectValue.class

getCellSerializer

public static DataCellSerializer<PortObjectCell> getCellSerializer()

Serializer as required by parent class.

Returns:

A serializer for reading/writing cells of this kind.

getPortObject

public PortObject getPortObject()

Get content of this port object.

Specified by:

getPortObject in interface PortObjectValue

Returns:

The PortObject content, never null.

toString

public String toString()

Returns the String representation of this cell's value.

Specified by:

toString in class DataCell

Returns:

a String representation of this cell's value

equalsDataCell

protected boolean equalsDataCell(DataCell dc)

Derived classes implement their specific equals function here. The argument is guaranteed to be not null or a missing value, to be of the same class like this.

Specified by:

equalsDataCell in class DataCell

Parameters:

dc - the cell to compare this to

Returns:

true if this is equal to the argument, false if not

hashCode

public int hashCode()

This method must be implemented in order to ensure that two equal DataCell objects return the same hash code.

Specified by:

hashCode in class DataCell

Returns:

the hash code of your specific DataCell
