If null, then the Mapper value can be applied as an Intermediate variable if the getBehavior(Class) has IntermediateResultMapperBehavior else it would apply itself on the core Entity

setFieldName

public void setFieldName(String fieldName)

The field the result of the mapper is intended for
If null, then the Mapper value can be applied as an Intermediate variable if the getBehavior(Class) has IntermediateResultMapperBehavior else it would apply itself on the core Entity

getEntityClass

public Class getEntityClass()

setEntityClass

public void setEntityClass(Class entityClass)

getId

public String getId()

During Error handling its useful to point @ the mapper if there is no fieldName specified

Specified by:

getId in interface Identifiable<String>

setId

public void setId(String id)

During Error handling its useful to point @ the mapper if there is no fieldName specified

Specified by:

setId in interface Identifiable<String>

getProcessor

public T getProcessor()

setProcessor

public void setProcessor(T processor)

The processor that will perform the processing activity.
T will be of type Transformer, Predicate or Chain
If null will return the original value as is

Can be null:

true
