Method Detail

getObjectFromColumn

Object getObjectFromColumn(ResultSet rs,
                           CallableStatement stmt,
                           String columnName,
                           int columnId)
                           throws SQLException

Returns an java object for this jdbc type by extract from the given CallableStatement or ResultSet.
NOTE: For internal use only!!
Exactly one of the arguments of type CallableStatement or ResultSet have to be non-null. If the 'columnId' argument is equals MIN_INT, then the given 'columnName' argument is used to lookup column. Else the given 'columnId' is used as column index.

Throws:

SQLException

getObjectFromColumn

Object getObjectFromColumn(CallableStatement stmt,
                           int columnId)
                           throws SQLException

Convenience method for getObjectFromColumn(ResultSet, CallableStatement, String, int)

Throws:

SQLException

getObjectFromColumn

Object getObjectFromColumn(ResultSet rs,
                           String columnName)
                           throws SQLException

Convenience method for getObjectFromColumn(ResultSet, CallableStatement, String, int)

Throws:

SQLException

sequenceKeyConversion

Object sequenceKeyConversion(Long identifier)
                             throws SequenceManagerException

Convert the given Long value to a java object representation of this jdbc type.

Throws:

SequenceManagerException

getType

int getType()

Returns the representing sql type.

equals

boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

Overrides:

equals in class Object

getFieldType

FieldType getFieldType()

Returns the associated FieldType (java field type mapped to this sql type).
