initialize
public void initialize(org.datanucleus.metadata.AbstractMemberMetaData mmd, Table table, org.datanucleus.ClassLoaderResolver clr) Initialize this JavaTypeMapping for the given member MetaData and Table owning it.- Overrides:
initialize
in classSingleFieldMapping
- Parameters:
mmd
- MetaData for the member to be mapped (if any)table
- The table storing this mapping (if any)clr
- the ClassLoaderResolver
-
getValidValues
Accessor for the valid values for this mapping (if any restriction is imposed).- Overrides:
getValidValues
in classSingleFieldMapping
- Parameters:
index
- The index of the datastore column- Returns:
- The valid value(s)
-
getJavaTypeForColumnMapping
Accessor for the name of the java-type actually used when mapping the particular datastore field. This java-type must have an entry in the datastore mappings.- Overrides:
getJavaTypeForColumnMapping
in classSingleFieldMapping
- Parameters:
index
- requested column index.- Returns:
- the name of java-type for the requested column.
-
getJavaType
Description copied from class:JavaTypeMapping
Accessor for the java type being mapped. This is the java type that the mapping represents. Some examples :- if the field is of type "MyClass" then the mapping will be OIDMapping (or subclass) the javaType will be OID, and the type will be MyClass.
- if the field is of type "int" then the mapping will be IntegerMapping, the javaType will be Integer, and the type will be int.
- Specified by:
getJavaType
in classJavaTypeMapping
- Returns:
- The java type
-
setObject

getObject
Description copied from class:JavaTypeMapping
Obtains a value fromdatastoreResults
at position specified byexprIndex
.- Overrides:
getObject
in classSingleFieldMapping
- Parameters:
ec
- ExecutionContextresultSet
- ResultSetexprIndex
- the position of the value in the result- Returns:
- the value
