public class DbSmallInt
extends DbNumber

The DbSmallInt class wraps a value of the primitive type short in an object. An object of the type DbSmallInt contains a single field whose type is short.

In addition, this class provides several methods for converting a DbSmallInt to a String or other number types, as well as other constants and methods used when dealing with a DbSmallInt.

Field Detail

value

public short value

Deprecated.

The field contains the value of this object. Note use get and set to access it instead of accessing it directly.

Constructor Detail

DbSmallInt

public DbSmallInt()

Constructs an uninitialized DbSmallInt. This DbSmallInt object is mutable until a nonzero value and the description of column are set.

DbSmallInt

public DbSmallInt(DbColDesc desc)

Constructs an uninitialized DbSmallInt. This DbSmallInt object is mutable until the value is set.

Parameters:

desc - The value to be represented by the DbColDesc object.

Method Detail

get

public short get()

Returns the value of this DbSmallInt as a short value.

set

public void set(short v)

Sets a newly allocated DbSmallInt object that represents the specified short argument.

Parameters:

v - The short value to be represented by the DbSmallInt object.

set

public void set(java.sql.ResultSet rs,
                int col)
         throws java.sql.SQLException

Sets a newly allocated DbSmallInt object that represents the short value indicated by the ResultSet parameter and an index of the column.

Specified by:

set in class DbValue

Parameters:

rs - The ResultSet to be fetched.

col - The index of the column.

Throws:

java.sql.SQLException - if the ResultSet does not contain the index.

set

public void set(JRHierarchicalDataset hds,
                int col)
         throws java.sql.SQLException

Sets a newly allocated DbSmallInt object that represents the short value indicated by the JRHierarchicalDataset parameter and an index of the column.

Overrides:

set in class DbValue

Parameters:

hds - The JRHierarchicalDataset to be fetched.

col - The index of the column.

Throws:

java.sql.SQLException - if the ResultSet does not contain the index.

toString

public java.lang.String toString()

Returns a String object representing this DbSmallInt's value. The value is converted to signed decimal representation and returned as a string. If the value is null, it returns "NULL".

Specified by:

toString in class DbValue

Returns:

a string representation of the value of this object in base 10.

clone

public java.lang.Object clone()

Creates a clone of this DbSmallInt object.

Specified by:

clone in interface jet.util.DbValueable

Specified by:

clone in class DbValue

equals

public boolean equals(DbNumber v)

Compares this object to the specified object. The result is true if and only if the argument is not null but a DbSmallInt object that contains the same DbNumber value as this object.

Specified by:

equals in class DbNumber

Parameters:

obj - The DbNumber object to be compared with.

Returns:

true if the objects are the same; false otherwise.

byteValue

public byte byteValue()

Returns the value of this DbSmallInt as a byte.

Specified by:

byteValue in class DbNumber

shortValue

public short shortValue()

Returns the value of this DbSmallInt as a short.

Specified by:

shortValue in class DbNumber

intValue

public int intValue()

Returns the value of this DbSmallInt as an int.

Specified by:

intValue in class DbNumber

longValue

public long longValue()

Returns the value of this DbSmallInt as a long value.

Specified by:

longValue in class DbNumber

floatValue

public float floatValue()

Returns the value of this DbSmallInt as a float.

Specified by:

floatValue in class DbNumber

doubleValue

public double doubleValue()

Returns the value of this DbSmallInt as a double.

Specified by:

doubleValue in class DbNumber

setValue

public void setValue(DbNumber v)

Sets a newly allocated DbSmallInt object that represents the short value indicated by the DbNumber parameter. The DbNumber object will be checked to see if it is null,

Specified by:

setValue in class DbNumber

Parameters:

v - The DbNumber to be converted to a DbSmallInt. If it is null, the value will not be set.

setValue

public void setValue(java.lang.String v)

Sets a newly allocated DbSmallInt object that represents the short value indicated by the String parameter. The string is converted to a short value in exactly the manner used by the parseShort method for radix 10.

Specified by:

setValue in class DbValue

Parameters:

v - The String to be converted to a DbSmallInt. The argument is interpreted as representing a signed decimal short, which is exactly as if the argument were given to the parseShort method.

toStringValue

public java.lang.String toStringValue()

Specified by:

toStringValue in class DbValue

Returns:

a string which will represent the value in the DbValue(null flag and value). When compare StringValue from DbValues, we always assume that: the two DbValues have same DbColDesc. Two StringValue equals means the original DbValue equals. Does NOT transfer the compareTo(DbValue v) method. Only comparable dbValue implements this methods. String coding uses Base64.
