Field Detail

INSTANCE

public static final BigIntegerTypeDescriptor INSTANCE
Constructor Detail

BigIntegerTypeDescriptor

public BigIntegerTypeDescriptor()
Method Detail

toString

public String toString(BigInteger value)

fromString

public BigInteger fromString(String string)

extractHashCode

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

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

areEqual

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

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

unwrap

public <X> X unwrap(BigInteger value,
                    Class<X> type,
                    WrapperOptions options)
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> BigInteger wrap(X value,
                           WrapperOptions options)
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.
