org.hibernate.type.descriptor.jdbc.EnumJdbcType

All Implemented Interfaces:

Serializable, JdbcType

Direct Known Subclasses:

OrdinalEnumJdbcType

public class EnumJdbcType
extends Object
implements JdbcType

Represents an enum type for databases like MySQL and H2.

Hibernate will automatically use this for enums mapped as EnumType.STRING.

Method Details

getJdbcTypeCode

public int getJdbcTypeCode()

Description copied from interface: JdbcType

The JDBC type code used when interacting with JDBC APIs.

For example, it's used when calling PreparedStatement.setNull(int, int).

Specified by:

getJdbcTypeCode in interface JdbcType

Returns:

a JDBC type code

getDefaultSqlTypeCode

public int getDefaultSqlTypeCode()

Description copied from interface: JdbcType

A JDBC type code that identifies the SQL column type.

This value might be different from JdbcType.getDdlTypeCode() if the actual type e.g. JSON is emulated through a type like CLOB.

Specified by:

getDefaultSqlTypeCode in interface JdbcType

Returns:

a JDBC type code

getJdbcLiteralFormatter

public <T> JdbcLiteralFormatter<T> getJdbcLiteralFormatter(JavaType<T> javaType)

Description copied from interface: JdbcType

Obtain a formatter object capable of rendering values of the given Java type as SQL literals of the type represented by this object.

Specified by:

getJdbcLiteralFormatter in interface JdbcType

getFriendlyName

public String getFriendlyName()

Description copied from interface: JdbcType

A "friendly" name for use in logging

Specified by:

getFriendlyName in interface JdbcType

getPreferredJavaTypeClass

public Class<?> getPreferredJavaTypeClass(WrapperOptions options)

Description copied from interface: JdbcType

The Java type class that is preferred by the binder or null.

Specified by:

getPreferredJavaTypeClass in interface JdbcType

getBinder

public <X> ValueBinder<X> getBinder(JavaType<X> javaType)

Description copied from interface: JdbcType

Obtain a binder object capable of binding values of the given Java type to parameters of a JDBC PreparedStatement.

Specified by:

getBinder in interface JdbcType

Parameters:

javaType - The descriptor describing the types of Java values to be bound

Returns:

The appropriate binder.

getExtractor

public <X> ValueExtractor<X> getExtractor(JavaType<X> javaType)

Description copied from interface: JdbcType

Obtain an extractor object capable of extracting values of the given Java type from a JDBC ResultSet.

Specified by:

getExtractor in interface JdbcType

Parameters:

javaType - The descriptor describing the types of Java values to be extracted

Returns:

The appropriate extractor
