mapField

public AbstractFieldMapping mapField(ExpressionContext expressionContext,

Specified by:

mapField in interface IFieldMapping

mapFieldImpl

protected abstract Object mapFieldImpl(ExpressionContext expressionContext,
                                       DataMappingResult result)

validateName

protected void validateName()

toRecord

public Record toRecord()

Specified by:

toRecord in interface RecordSerializable

Overrides:

toRecord in class Bean

fromRecord

public AbstractFieldMapping fromRecord(Record source)

Description copied from interface: RecordSerializable

Loads this instance's state from a record and returns this (for fluid API call chaining). For fluid API call chaining, the overridden method should change the declared return type to its class.

Specified by:

fromRecord in interface RecordSerializable

Overrides:

fromRecord in class Bean

Returns:

this instance.

addExceptionProperties

public DataException addExceptionProperties(DataException exception)

Description copied from class: FoundationObject

Adds this object's current state to a DataException. Since this method is called whenever an exception is thrown, subclasses should override it to add their specific information.

Overrides:

addExceptionProperties in class FoundationObject

toXmlElement

public Element toXmlElement(Document document)

Specified by:

toXmlElement in interface XmlSerializable

fromXmlElement

public AbstractFieldMapping fromXmlElement(Element fieldMappingElement)

Specified by:

fromXmlElement in interface XmlSerializable
