Class SQLClob

java.lang.Object
  org.apache.derby.iapi.types.DataType
      org.apache.derby.iapi.types.SQLChar
          org.apache.derby.iapi.types.SQLVarchar
              org.apache.derby.iapi.types.SQLClob

All Implemented Interfaces:: CloneableObject, ConcatableDataValue, DataValueDescriptor, java.io.Externalizable, org.apache.derby.iapi.services.io.Formatable, Orderable, java.io.Serializable, org.apache.derby.iapi.services.io.Storable, org.apache.derby.iapi.services.io.StreamStorable, StringDataValue, org.apache.derby.iapi.services.io.TypedFormat, VariableSizeDataValue

public class SQLClob
extends SQLVarchar

SQLClob uses SQLVarchar by inheritance. It satisfies the DataValueDescriptor interfaces (i.e., OrderableDataType). It implements a String holder, e.g. for storing a column value; it can be specified when constructed to not allow nulls. Nullability cannot be changed after construction.

Because OrderableDataType is a subclass of DataType, SQLLongvarchar can play a role in either a DataType/ValueRow or a OrderableDataType/KeyRow, interchangeably.

public SQLClob(java.lang.String val)

Method Detail

getTypeName

public java.lang.String getTypeName()

Description copied from interface: DataValueDescriptor

Get the SQL name of the datatype

Specified by:: getTypeName in interface DataValueDescriptor
Overrides:: getTypeName in class SQLVarchar

getClone

public DataValueDescriptor getClone()

Description copied from interface: DataValueDescriptor

Clone this DataValueDescriptor. Results in a new object that has the same value as this but can be modified independently.

Specified by:: getClone in interface DataValueDescriptor
Overrides:: getClone in class SQLVarchar

getNewNull

public DataValueDescriptor getNewNull()

Description copied from interface: DataValueDescriptor

Get a new null value of the same type as this data value.

Specified by:: getNewNull in interface DataValueDescriptor
Overrides:: getNewNull in class SQLVarchar

getTypeFormatId

public int getTypeFormatId()

Return my format identifier.

Specified by:: getTypeFormatId in interface org.apache.derby.iapi.services.io.TypedFormat
Overrides:: getTypeFormatId in class SQLVarchar

typePrecedence

public int typePrecedence()

Description copied from interface: DataValueDescriptor

Each built-in type in JSQL has a precedence. This precedence determines how to do type promotion when using binary operators. For example, float has a higher precedence than int, so when adding an int to a float, the result type is float. The precedence for some types is arbitrary. For example, it doesn't matter what the precedence of the boolean type is, since it can't be mixed with other types. But the precedence for the number types is critical. The SQL standard requires that exact numeric types be promoted to approximate numeric when one operator uses both. Also, the precedence is arranged so that one will not lose precision when promoting a type.

Specified by:: typePrecedence in interface DataValueDescriptor
Overrides:: typePrecedence in class SQLVarchar

getObject

public java.lang.Object getObject()
                           throws org.apache.derby.iapi.error.StandardException

Description copied from interface: DataValueDescriptor

Gets the value in the data value descriptor as a Java Object. The type of the Object will be the Java object type corresponding to the data value's SQL type. JDBC defines a mapping between Java object types and SQL types - we will allow that to be extended through user type definitions. Throws an exception if the data value is not an object (yeah, right).

Specified by:: getObject in interface DataValueDescriptor
Overrides:: getObject in class SQLChar

getBoolean

public boolean getBoolean()
                   throws org.apache.derby.iapi.error.StandardException

Description copied from interface: DataValueDescriptor

Gets the value in the data value descriptor as a boolean. Throws an exception if the data value is not a boolean. For DataValueDescriptor, this is the preferred interface for BIT, but for this no-casting interface, it isn't, because BIT is stored internally as a Bit, not as a Boolean.

Specified by:: getBoolean in interface DataValueDescriptor
Overrides:: getBoolean in class SQLChar

getByte

public byte getByte()
             throws org.apache.derby.iapi.error.StandardException

Description copied from interface: DataValueDescriptor

Specified by:: getByte in interface DataValueDescriptor
Overrides:: getByte in class SQLChar

getShort

public short getShort()
               throws org.apache.derby.iapi.error.StandardException

Description copied from interface: DataValueDescriptor

Gets the value in the data value descriptor as a short. Throws an exception if the data value is not a short.

Specified by:: getShort in interface DataValueDescriptor
Overrides:: getShort in class SQLChar

getInt

public int getInt()
           throws org.apache.derby.iapi.error.StandardException

Description copied from interface: DataValueDescriptor

Specified by:: getInt in interface DataValueDescriptor
Overrides:: getInt in class SQLChar

getLong

public long getLong()
             throws org.apache.derby.iapi.error.StandardException

Description copied from interface: DataValueDescriptor

Gets the value in the data value descriptor as a long. Throws an exception if the data value is not a long.

Specified by:: getLong in interface DataValueDescriptor
Overrides:: getLong in class SQLChar

getFloat

public float getFloat()
               throws org.apache.derby.iapi.error.StandardException

Description copied from interface: DataValueDescriptor

Gets the value in the data value descriptor as a float. Throws an exception if the data value is not a float.

Specified by:: getFloat in interface DataValueDescriptor
Overrides:: getFloat in class SQLChar

getDouble

public double getDouble()
                 throws org.apache.derby.iapi.error.StandardException

Specified by:: getBytes in interface DataValueDescriptor
Overrides:: getBytes in class DataType
