public static LongObjectType getSingleton()

parseDefaultString

public Object parseDefaultString(FieldType fieldType,
                                 String defaultStr)
Description copied from interface: FieldConverter
Convert a default string object and return the appropriate argument to a SQL insert or update statement.

Specified by:
parseDefaultString in interface FieldConverter
Specified by:
parseDefaultString in class BaseDataType

resultToJava

public Object resultToJava(FieldType fieldType,
                           DatabaseResults results,
                           int columnPos)
                    throws SQLException
Description copied from interface: FieldConverter
Return the object extracted from the results associated with column in position columnPos.

Specified by:
resultToJava in interface FieldConverter
Specified by:
resultToJava in class BaseDataType
Parameters:
fieldType - Associated FieldType which may be null.
Throws:
SQLException - If there is a problem accessing the results data.

isValidForField

public boolean isValidForField(Field field)
Description copied from interface: DataPersister
Return true if the field is appropriate for this persister.

Specified by:
isValidForField in interface DataPersister
Specified by:
isValidForField in class BaseDataType

convertIdNumber

public Object convertIdNumber(Number number)
Description copied from interface: DataPersister
Convert a Number object to its primitive object suitable for assigning to an ID field.

Specified by:
convertIdNumber in interface DataPersister
Overrides:
convertIdNumber in class BaseDataType

isEscapedValue

public boolean isEscapedValue()
Description copied from interface: DataPersister
Return whether we need to escape this value in SQL expressions. Numbers _must_ not be escaped but most other values should be.

isEscapedValue in interface DataPersister
Overrides:
isEscapedValue in class BaseDataType

isValidGeneratedType

public boolean isValidGeneratedType()
Description copied from interface: DataPersister
Return true if this type can be auto-generated by the database. Probably only numbers will return true.

Specified by:
isValidGeneratedType in interface DataPersister
Overrides:
isValidGeneratedType in class BaseDataType

isValidForVersion

public boolean isValidForVersion()
Description copied from interface: DataPersister
Return true if this is a valid field for the DatabaseField.version().

Specified by:
isValidForVersion in interface DataPersister
Overrides:
isValidForVersion in class BaseDataType

moveToNextValue

public Object moveToNextValue(Object currentValue)
Description copied from interface: DataPersister
Move the current-value to the next value. Used for the version field.

Specified by:
moveToNextValue in interface DataPersister
Overrides:
moveToNextValue in class BaseDataType
