Method Detail

getRecommendedJdbcType
public JdbcType getRecommendedJdbcType(JdbcTypeIndicators context)
Description copied from interface:BasicJavaType
Obtain the "recommended"SQL type descriptor
for this Java type. Often, but not always, the source of this recommendation is the JDBC specification.- Parameters:
context
- Contextual information- Returns:
- The recommended SQL type descriptor
-
extractHashCode
public int extractHashCode(T value)
Description copied from interface:JavaType
Extract a proper hash code for the given value.- Specified by:
extractHashCode
in interfaceJavaType<T>
- Overrides:
extractHashCode
in classAbstractClassJavaType<T>
- Parameters:
value
- The value for which to extract a hash code.- Returns:
- The extracted hash code.
-
areEqual
public boolean areEqual(T one, T another)
Description copied from interface:JavaType
Determine if two instances are equal
-
isInstance
public boolean isInstance(Object value)
Description copied from interface:JavaType
Is the given value an instance of the described type?Usually just
getJavaTypeClass().
isInstance(value)
, but some descriptors need specialized semantics, for example, the descriptors forjava.sql.Date
,java.sql.Time
, andjava.sql.Timestamp
.

fromString
public T fromString(CharSequence string)
-
unwrap
public <X> X unwrap(T 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 theInteger value
as aLong
, we would return something likeLong.valueOf( value.longValue() )
.Intended use is during
PreparedStatement
binding.- Type Parameters:
X
- The conversion type.- Parameters:
value
- The value to unwraptype
- The type as which to unwrapoptions
- The options- Returns:
- The unwrapped value.
-
wrap
public <X> T wrap(X value, WrapperOptions options)
Description copied from interface:JavaType
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.
