-
convertClassNamesToClasses
public void convertClassNamesToClasses(java.lang.ClassLoader classLoader)
INTERNAL: Convert all the class-name-based settings in this query to actual class-based settings. This method is used when converting a project that has been built with class names to a project with classes.- Overrides:
convertClassNamesToClassesin classSQLResult- Parameters:
classLoader-
-
getFieldResults
public java.util.Map getFieldResults()
Accessor for the internally stored list of FieldResult. Calling this method will result in a collection being created to store the FieldResult
-
getDiscriminatorColumn
public org.eclipse.persistence.internal.helper.DatabaseField getDiscriminatorColumn()
Returns the column name for the column that will store the value used to determine the subclass type if applicable.
-
setDiscriminatorColumn
public void setDiscriminatorColumn(java.lang.String column)
Sets the column name for the column that will store the value used to determine the subclass type if applicable.
-
setDiscriminatorColumn
public void setDiscriminatorColumn(org.eclipse.persistence.internal.helper.DatabaseField column)
-
getValueFromRecord
public java.lang.Object getValueFromRecord(DatabaseRecord record, ResultSetMappingQuery query)
INTERNAL: This method is a convenience method for extracting values from Results- Specified by:
getValueFromRecordin classSQLResult
-
isEntityResult
public boolean isEntityResult()
Description copied from class:SQLResultReturn true if this is an entity result.- Overrides:
isEntityResultin classSQLResult
-
getValueFromRecordForMapping
public void getValueFromRecordForMapping(DatabaseRecord entityRecord, DatabaseMapping mapping, FieldResult fieldResult, DatabaseRecord databaseRecord)
INTERNAL: This method is for processing all FieldResults for a mapping. Adds DatabaseFields to the passed in entityRecord
-
processValueFromRecordForMapping
public org.eclipse.persistence.internal.helper.DatabaseField processValueFromRecordForMapping(ClassDescriptor descriptor, java.lang.String[] attributeNames, int currentLoc)
INTERNAL: This method is for processing a single FieldResult, returning the DatabaseField it refers to.
