getRecommendedJdbcType
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.- Specified by:
getRecommendedJdbcType
in interfaceBasicJavaType<Double>
- Specified by:
getRecommendedJdbcType
in interfaceJavaType<Double>
- Parameters:
indicators
- Contextual information- Returns:
- The recommended SQL type descriptor
-
useObjectEqualsHashCode
public boolean useObjectEqualsHashCode()Description copied from interface:JavaType
Whether to useObject.equals(Object)
andObject.hashCode()
orJavaType.areEqual(Object, Object)
andJavaType.extractHashCode(Object)
for objects of this java type. This is useful to avoid mega-morphic callsites.- Specified by:
useObjectEqualsHashCode
in interfaceJavaType<Double>
-
toString
-
fromString
- Specified by:
fromString
in interfaceBasicJavaType<Double>
- Specified by:

in interfaceJavaType<Double>
-
unwrap
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. -
wrap
Description copied from interface:JavaType
Wrap a value as our handled Java type.Intended use is during
ResultSet
extraction. -
isWider
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. -
getPrimitiveClass
Description copied from interface:PrimitiveJavaType
Retrieve the primitive counterpart to the wrapper type identified by this descriptor- Specified by:
getPrimitiveClass
in interfacePrimitiveJavaType<Double>
- Returns:
- The primitive Java type.
-
getArrayClass
Description copied from interface:PrimitiveJavaType
Get the Java type that describes an array of this type.- Specified by:
getArrayClass
in interfacePrimitiveJavaType<Double>
-
getPrimitiveArrayClass
Description copied from interface:PrimitiveJavaType
Get the Java type that describes an array of this type's primitive variant.- Specified by:
getPrimitiveArrayClass
in interfacePrimitiveJavaType<Double>
-
getDefaultValue
Description copied from interface:JavaType
Get this Java type's default value.- Specified by:
getDefaultValue
in interfaceJavaType<Double>
- Returns:
- The default value.
-
getDefaultSqlLength
Description copied from interface:JavaType
The default column length when this Java type is mapped to a SQL data type which is parametrized by length, for exampleTypes.VARCHAR
.- Specified by:
