Constructor Detail

BOOLEAN

public BOOLEAN(byte[] _bytes)

Construct a BOOLEAN from a byte array.

Parameters:

_bytes - input data from which this class instance is constructed.

BOOLEAN

public BOOLEAN(boolean bool)

Construct a BOOLEAN from a primitive boolean.

Parameters:

bool - input data from which this class instance is constructed.

BOOLEAN

public BOOLEAN(java.lang.Boolean bool)

Construct a BOOLEAN from an instance of java.lang.Boolean.

Parameters:

bool - input data from which this class instance is constructed.

Method Detail

isConvertibleTo

public boolean isConvertibleTo(java.lang.Class<?> cls)

Determines if the object can be converted to a particular class

Specified by:

isConvertibleTo in class Datum

Parameters:

cls - Class to convert to

Returns:

true, if conversion to cls is permitted false, if conversion to cls is not permitted

toJdbc

public java.lang.Object toJdbc()
                        throws java.sql.SQLException

Returns the JDBC representation of the datum object

Specified by:

toJdbc in class Datum

Returns:

an object containing the JDBC value

Throws:

java.sql.SQLException - if conversion to JDBC representation results in an error

toBooleanValue

public boolean toBooleanValue()
                       throws java.sql.SQLException

Calls toBoolean to convert into a Java Boolean.

Returns:

a Java Boolean value

Throws:

java.sql.SQLException

booleanValue

public boolean booleanValue()
                     throws java.sql.SQLException

Calls toBooleanValue() to convert into a Java Boolean.

Overrides:

booleanValue in class Datum

Returns:

Java boolean representation of this object

Throws:

java.sql.SQLException

toBoolean

public static boolean toBoolean(byte[] bytes)

Convert an Oracle Number to a Java boolean. A zero value translates to false and non-zero values translate to true

Parameters:

bytes - in byte array format

Returns:

a Java boolean value

makeJdbcArray

public java.lang.Object makeJdbcArray(int arraySize)

Returns a JDBC array representation of the datum

Specified by:

makeJdbcArray in class Datum

Parameters:

arraySize - size of the array

Returns:

an object containing the JDBC array value

Throws:

java.sql.SQLException - if conversion to JDBC array representation results in an error
