Constructor Detail

AbstractDataType

public AbstractDataType(java.lang.String name,
                        int sqlType,
                        java.lang.Class classType,
                        boolean isNumber)

Method Detail

compare

public int compare(java.lang.Object o1,
                   java.lang.Object o2)
            throws TypeCastException

Description copied from class: DataType

Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

The two values are typecast to this DataType before being compared.

Specified by:

compare in class DataType

Throws:

TypeCastException - if the arguments' types prevent them from being compared by this Comparator.

compareNonNulls

protected int compareNonNulls(java.lang.Object value1,
                              java.lang.Object value2)
                       throws TypeCastException

Compares non-null values to each other. Both objects are guaranteed to be not null and to implement the interface Comparable. The two given objects are the results of the DataType.typeCast(Object) method call which is usually implemented by a specialized DataType implementation.

Parameters:

value1 - First value resulting from the DataType.typeCast(Object) method call

value2 - Second value resulting from the DataType.typeCast(Object) method call

Returns:

The result of the Comparable.compareTo(Object) invocation.

Throws:

TypeCastException

areObjectsEqual

protected final boolean areObjectsEqual(java.lang.Object o1,
                                        java.lang.Object o2)

Checks whether the given objects are equal or not.

Parameters:

o1 - first object

o2 - second object

Returns:

true if both objects are null (and hence equal) or if the o1.equals(o2) is true.

getSqlType

public int getSqlType()

Description copied from class: DataType

Returns the corresponding Types.

Specified by:

getSqlType in class DataType

getTypeClass

public java.lang.Class getTypeClass()

Description copied from class: DataType

Returns the runtime class of the typecast result.

Specified by:

getTypeClass in class DataType

isNumber

public boolean isNumber()

Description copied from class: DataType

Returns true if this DataType represents a number.

Specified by:

isNumber in class DataType

isDateTime

public boolean isDateTime()

Description copied from class: DataType

Returns true if this DataType represents a date and/or time.

Specified by:

isDateTime in class DataType

getSqlValue

public java.lang.Object getSqlValue(int column,
                                    java.sql.ResultSet resultSet)
                             throws java.sql.SQLException,
                                    TypeCastException

Description copied from class: DataType

Returns the specified column value from the specified resultset object.

Specified by:

getSqlValue in class DataType

Throws:

java.sql.SQLException

TypeCastException

setSqlValue

public void setSqlValue(java.lang.Object value,
                        int column,
                        java.sql.PreparedStatement statement)
                 throws java.sql.SQLException,
                        TypeCastException

Description copied from class: DataType

Set the specified value to the specified prepared statement object.

Specified by:

setSqlValue in class DataType

Throws:

java.sql.SQLException

TypeCastException

loadClass

protected final java.lang.Class loadClass(java.lang.String clazz,
                                          java.sql.Connection connection)
