Method Detail

toString

public String toString(Long value)

Specified by:

toString in interface JavaType<Long>

fromString

public Long fromString(CharSequence string)

Specified by:

fromString in interface BasicJavaType<Long>

Specified by:

fromString in interface JavaType<Long>

unwrap

public <X> X unwrap(Long value,
                    Class<X> type,
                    WrapperOptions options)

Description copied from interface: JavaType

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.

Specified by:

unwrap in interface JavaType<Long>

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> Long wrap(X value,
                     WrapperOptions options)

Description copied from interface: JavaType

Wrap a value as our handled Java type.

Intended use is during ResultSet extraction.

Specified by:

wrap in interface JavaType<Long>

Type Parameters:

X - The conversion type.

Parameters:

value - The value to wrap.

options - The options

Returns:

The wrapped value.

isWider

public boolean isWider(JavaType<?> javaType)

Description copied from interface: JavaType

Returns whether this java type is wider than the given type i.e. if the given type can be widened to this java type.

Specified by:

isWider in interface JavaType<Long>

coerce

public <X> Long coerce(X value,
                       JavaType.CoercionContext coercionContext)

Specified by:

coerce in interface JavaType<Long>

getPrimitiveClass

public Class getPrimitiveClass()

Description copied from interface: PrimitiveJavaType

Retrieve the primitive counterpart to the wrapper type identified by this descriptor

Specified by:

getPrimitiveClass in interface PrimitiveJavaType<Long>

Returns:

The primitive Java type.

getArrayClass

public Class<Long[]> getArrayClass()

Description copied from interface: PrimitiveJavaType

Description copied from interface: JavaType

Get this Java type's default value.

Specified by:

getDefaultValue in interface JavaType<Long>

Returns:

The default value.
