                       char characterValueFalse)

Method Detail

toString

public String toString(Boolean value)

Specified by:

toString in interface JavaType<Boolean>

fromString

public Boolean fromString(CharSequence string)

Specified by:

fromString in interface BasicJavaType<Boolean>

Specified by:

fromString in interface JavaType<Boolean>

fromEncodedString

public Boolean fromEncodedString(CharSequence charSequence,
                                 int start,
                                 int end)

Description copied from interface: JavaType

Reads the encoded value from the char sequence start index until the end index and returns the decoded value. Implementers do not need to care about escaping. This is similar to JavaType.fromString(CharSequence), with the difference that the aim of this method is decoding from a range within an existing char sequence.

Specified by:

fromEncodedString in interface JavaType<Boolean>

unwrap

public <X> X unwrap(Boolean 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<Boolean>

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> Boolean 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<Boolean>

Type Parameters:

X - The conversion type.

Parameters:

value - The value to wrap.

options - The options

Returns:

The wrapped value.

toInt

public int toInt(Boolean value)

toByte

public Byte toByte(Boolean value)

toShort

public Short toShort(Boolean value)

toInteger

public Integer toInteger(Boolean value)

toLong

public Long toLong(Boolean value)

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<Boolean>

Returns:

The primitive Java type.

getArrayClass

public Class<Boolean[]> getArrayClass()

Description copied from interface: PrimitiveJavaType

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

Specified by:

getArrayClass in interface PrimitiveJavaType<Boolean>

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:

getPrimitiveArrayClass in interface PrimitiveJavaType<Boolean>

getDefaultValue

Specified by:

getDefaultSqlLength in interface JavaType<Boolean>

Returns:

Size.DEFAULT_LENGTH unless overridden
