Package org.hibernate.dialect

Class PostgreSQLEnumJdbcType

java.lang.Object

org.hibernate.dialect.PostgreSQLEnumJdbcType

All Implemented Interfaces:

Serializable, JdbcType

Direct Known Subclasses:

PostgreSQLOrdinalEnumJdbcType

public class PostgreSQLEnumJdbcType
extends Object
implements JdbcType

Represents a named enum type on PostgreSQL.

Hibernate does not automatically use this for enums mapped as EnumType.STRING, and instead this type must be explicitly requested using:

 @JdbcTypeCode(SqlTypes.NAMED_ENUM)
 

See Also:

• SqlTypes.NAMED_ENUM
• PostgreSQLDialect.getEnumTypeDeclaration(String, String[])
• PostgreSQLDialect.getCreateEnumTypeCommand(String, 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

toString

public String toString()

Overrides:

toString in class Object

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

addAuxiliaryDatabaseObjects

public void addAuxiliaryDatabaseObjects(JavaType<?> javaType,
 BasicValueConverter<?,?> valueConverter,
 Size columnSize,
 Database database,
 JdbcTypeIndicators context)

Description copied from interface: JdbcType

Add auxiliary database objects for this JdbcType to the Database object.

Specified by:

addAuxiliaryDatabaseObjects in interface JdbcType
