BytesDataType

public BytesDataType(String name,
 int sqlType)

Method Details

loadFile

public byte[] loadFile(String filename)
                throws IOException

Throws:

IOException

loadURL

public byte[] loadURL(String urlAsString)
               throws IOException

Throws:

IOException

typeCast

public Object typeCast(Object value)
                throws TypeCastException

Casts the given value into a byte[] using different strategies. Note that this might sometimes result in undesired behavior when character data (Strings) are used.

Specified by:

typeCast in class DataType

Throws:

TypeCastException

See Also:

• DataType.typeCast(java.lang.Object)

compareNonNulls

protected int compareNonNulls(Object value1,
 Object value2)
                       throws TypeCastException

Description copied from class: AbstractDataType

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.

Overrides:

compareNonNulls in class AbstractDataType

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

compare

public int compare(byte[] v1,
 byte[] v2)
            throws TypeCastException

Throws:

TypeCastException

getSqlValue

public Object getSqlValue(int column,
 ResultSet resultSet)
                   throws SQLException,
TypeCastException

Description copied from class: DataType

Returns the specified column value from the specified resultset object.

Overrides:

getSqlValue in class AbstractDataType

Throws:

SQLException

TypeCastException

setSqlValue

public void setSqlValue(Object value,
 int column,
 PreparedStatement statement)
                 throws SQLException,
TypeCastException

Description copied from class: DataType

Set the specified value to the specified prepared statement object.

Overrides:

setSqlValue in class AbstractDataType

Throws:

SQLException
