Description
Interface Summary | |
BLOBValue | A BLOB (Binary Large Object) is a LOB oriented to storage bytes. |
CLOBValue | A CLOB (Character Large Object) is a LOB oriented to storage characters. |
ID | This interface represents the identifiers of semistructured data. |
LOBValue | A LOBValue is an special case of PrimitiveValue ,
designed to manage very large objects that can not be stored or easily manipulated in memory.
|
NonPrimitiveValue | This interface represents a non primitive value for a semistructured datum. |
PrimitiveValue | This interface represents a primitive value of a semistructured datum. |
SimpleValue | A SimpleValue is an special case of PrimitiveValue ,
designed for database managers, naively a simple value is a primitive value
that can be stored and easily manipulated in memory.
|
SSDValue | This interface represents the value of a semistructured datum. |
Class Summary | |
ByteSequenceValue | This class represents a sequence ob bytes. |
IntegerValue | This class represents a integer primitive value. |
Label | This class represents a label for a semistructured datum contained in other. |
LabeledSSD | LabeledSSD class represents labeled semistructured data
which actually are label-identifier pairs.
|
RealValue | This class represents a real primitive value. |
StringValue | This class represents a string primitive value. |
Exception Summary | |
BadLabelException | Thrown to indicate that a label tries to contain no word characters. |
BadSSDValueException | Thrown when a semistructured datum tries to own a invalid value. |
SSDException | SSDException and its subclasses are thrown to indicate an error
ocurred in semistructured data API. |
This package presents an API for manipulation of semistructured data.
Semistructured data emerged as one of the sevelal attempts to apply the techniques of database to data with no fixed structure. The semistructured data have not defined structure, they are self-descriptive.
Even semistructured data dont have fixed structure, we have to assume some primitive types like integers, reals, strings, etc. A semsitructured datum is a datum of primitive type or a set whose elements are labeled semistructured data. We also assume that each semistructured datum has a inique identifier.
