Method Detail

toString

public String toString(Integer value)

Specified by:

toString in interface JavaType<Integer>

fromString

public Integer fromString(CharSequence string)

Specified by:

fromString in interface BasicJavaType<Integer>

Specified by:

fromString in interface JavaType<Integer>

unwrap

public <X> X unwrap(Integer 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 JavaType<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<Integer>

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> Integer 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<Integer>

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

Determines if this Java type is wider than the given Java type, that is, if the given type can be safely widened to this type.

Specified by:

isWider in interface JavaType<Integer>

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<Integer>

Returns:

The primitive Java type.

getArrayClass

public Class<Integer[]> getArrayClass()

Description copied from interface: PrimitiveJavaType

Get the Java type that describes an array of this type.

Specified by:

getArrayClass in interface PrimitiveJavaType<Integer>

getPrimitiveArrayClass

public Class<?> getPrimitiveArrayClass()

Description copied from interface: PrimitiveJavaType

Get the Java type that describes an array of this type's primitive variant.

Specified by:

getDefaultValue

public Integer getDefaultValue()

Description copied from interface: JavaType

Get this Java type's default value.

Specified by:

getDefaultValue in interface JavaType<Integer>

Returns:

The default value.

Specified by:

getDefaultSqlLength in interface JavaType<Integer>

Returns:
