Method Summary

Modifier and Type	Method and Description
protected boolean	equalContent(DataValue otherValue) This method is called when two cell of different classes but with the same preferred value are compared (e.g.
protected boolean	equalsDataCell(DataCell dc) Derived classes implement their specific equals function here.
static DataCellSerializer<XMLBlobCell>	getCellSerializer() Deprecated. use DataTypeRegistry.getSerializer(Class) instead
Document	getDocument() Returns the parsed XML document.
String	getStringValue()
int	hashCode() This method must be implemented in order to ensure that two equal DataCell objects return the same hash code.
String	toString() Returns the String representation of this cell's value.

Constructor Detail

XMLBlobCell

public XMLBlobCell(XMLCellContent content)

Create a new instance.

Parameters:

content - the content of this cell

Method Detail

getCellSerializer

@Deprecated
public static DataCellSerializer<XMLBlobCell> getCellSerializer()

Deprecated. use DataTypeRegistry.getSerializer(Class) instead

Returns the serializer for XML cells.

Returns:

a serializer

getStringValue

public String getStringValue()

Specified by:

getStringValue in interface StringValue

Returns:

A String value.

getDocument

public Document getDocument()

Returns the parsed XML document. Note, as per definition of DataCell the returned document must not be modified by clients as data cells are read-only.

Specified by:

getDocument in interface XMLValue

Returns:

the DOM

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

equalContent

protected boolean equalContent(DataValue otherValue)

This method is called when two cell of different classes but with the same preferred value are compared (e.g. SdfCell and SdfAdapterCell or MolCell and MolBlobCell). All such cell classes should override this method with the same implementation, usually by comparing both preferred values. You can assume the this cell and the other cell have the same preferred value class, i.e. you can cast the argument to the preferred value.
The default implementation returns false.

Overrides:

equalContent in class DataCell

Parameters:

otherValue - the other data value

Returns:

true if the content of both cells is the same, false otherwise

hashCode

public int hashCode()

This method must be implemented in order to ensure that two equal DataCell objects return the same hash code. Note that two cells can be equal according to DataCell.equalsDataCell(DataCell) and DataCell.equalContent(DataValue) so two different cells implementations with the same preferred value must have the same hash code.

Specified by:

hashCode in class DataCell

Returns:

the hash code of your specific DataCell
