Package org.hibernate.dialect

Class AbstractPostgreSQLStructJdbcType

java.lang.Object

org.hibernate.dialect.AbstractPostgreSQLStructJdbcType

All Implemented Interfaces:

Serializable, AggregateJdbcType, JdbcType

Direct Known Subclasses:

PostgreSQLStructCastingJdbcType, PostgreSQLStructPGObjectJdbcType

public abstract class AbstractPostgreSQLStructJdbcType
extends Object
implements AggregateJdbcType

Implementation for serializing/deserializing an embeddable aggregate to/from the PostgreSQL component format. For regular queries, we select the individual struct elements because the PostgreSQL component format encoding is probably not very efficient.

Method Detail

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

getTypeName

public String getTypeName()

getEmbeddableMappingType

public EmbeddableMappingType getEmbeddableMappingType()

Specified by:

getEmbeddableMappingType in interface AggregateJdbcType

getJdbcRecommendedJavaTypeMapping

public <T> JavaType<T> getJdbcRecommendedJavaTypeMapping(Integer precision,
                                                         Integer scale,

Specified by:

getJdbcRecommendedJavaTypeMapping in interface JdbcType

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
