Method Detail

areEqual

public boolean areEqual(byte[] one,
                        byte[] another)
Description copied from class: AbstractTypeDescriptor
Determine if two instances are equal

Specified by:
areEqual in interface JavaTypeDescriptor<byte[]>
Overrides:
areEqual in class AbstractTypeDescriptor<byte[]>
Parameters:
one - One instance
another - The other instance
Returns:
True if the two are considered equal; false otherwise.

extractHashCode

public int extractHashCode(byte[] bytes)
Description copied from class: AbstractTypeDescriptor
Extract a proper hash code for this value.

Specified by:
extractHashCode in interface JavaTypeDescriptor<byte[]>
Overrides:
extractHashCode in class AbstractTypeDescriptor<byte[]>
Parameters:
bytes - The value for which to extract a hash code.
Returns:
The extracted hash code.

toString

public String toString(byte[] bytes)

fromString

public byte[] fromString(String string)

unwrap

public <X> X unwrap(byte[] value,
                    Class<X> type,
                    WrapperOptions options)
Description copied from interface: JavaTypeDescriptor
Unwrap an instance of our handled Java type into the requested type.

As an example, if this is a JavaTypeDescriptor<Integer> and we are asked to unwrap the Integer value as a Long we would return something like Long.valueOf( value.longValue() ).

Intended use is during PreparedStatement binding.

Type Parameters:
X - The conversion type.
Parameters:
value - The value to unwrap
type - The type as which to unwrap
options - The options
Returns:
The unwrapped value.

wrap

public <X> byte[] wrap(X value,
                       WrapperOptions options)
Description copied from interface: JavaTypeDescriptor
Wrap a value as our handled Java type.

Intended use is during ResultSet extraction.

Type Parameters:
X - The conversion type.
Parameters:
value - The value to wrap.
options - The options
Returns:
The wrapped value.
