Method Detail

setCondition

public FieldMapping setCondition(LogicalExpression condition)

Overrides:

setCondition in class AbstractFieldMapping

setDefaultValueExpression

public FieldMapping setDefaultValueExpression(Expression defaultValueExpression)

Overrides:

setDefaultValueExpression in class AbstractFieldMapping

setTargetFieldName

public FieldMapping setTargetFieldName(String targetFieldName)

Overrides:

setTargetFieldName in class AbstractFieldMapping

getSourceExpression

public Expression getSourceExpression()

setSourceExpression

public FieldMapping setSourceExpression(Expression sourceExpression)

getSourceExpressionAsString

public String getSourceExpressionAsString()

mapFieldImpl

protected Object mapFieldImpl(ExpressionContext expressionContext,
                              DataMappingResult result)

Specified by:

mapFieldImpl in class AbstractFieldMapping

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 AbstractFieldMapping

toRecord

public Record toRecord()

Specified by:

toRecord in interface RecordSerializable

Overrides:

toRecord in class AbstractFieldMapping

fromRecord

public FieldMapping 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 AbstractFieldMapping

Returns:

this instance.

toXmlElement

public Element toXmlElement(Document document)

Specified by:

toXmlElement in interface XmlSerializable

Overrides:

toXmlElement in class AbstractFieldMapping

fromXmlElement

public FieldMapping fromXmlElement(Element fieldMappingElement)

Specified by:

fromXmlElement in interface XmlSerializable

Overrides:

fromXmlElement in class AbstractFieldMapping
