Package org.hibernate.type.descriptor.java

Class ClobJavaType

java.lang.Object
org.hibernate.type.descriptor.java.AbstractClassJavaType<Clob>
org.hibernate.type.descriptor.java.ClobJavaType
All Implemented Interfaces:
Serializable, BasicJavaType<Clob>, JavaType<Clob>
public class ClobJavaType extends AbstractClassJavaType<Clob>
Descriptor for Clob handling.

Note, strictly-speaking a Clob object is actually mutable (its internal state can in fact be mutated). But we treat them as immutable because we simply have no way to dirty check nor deep copy them.

    • getRecommendedJdbcType

      public JdbcType getRecommendedJdbcType(JdbcTypeIndicators indicators)
      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:
      indicators - Contextual information
      Returns:
      The recommended SQL type descriptor

    • 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 for java.sql.Date, java.sql.Time, and java.sql.Timestamp.

    • extractLoggableRepresentation

      public String extractLoggableRepresentation(Clob value)
      Description copied from interface: JavaType
      Extract a loggable representation of the given value.
      Specified by:
      extractLoggableRepresentation in interface JavaType<Clob>
      Overrides:
      extractLoggableRepresentation in class AbstractClassJavaType<Clob>
      Parameters:
      value - The value for which to extract a loggable representation.
      Returns:
      The loggable representation

    • toString

      public String toString(Clob value)

    • fromString

      public Clob fromString(CharSequence string)

    • extractHashCode

      public int extractHashCode(Clob value)
      Description copied from interface: JavaType
      Extract a proper hash code for the given value.
      Specified by:
      extractHashCode in interface JavaType<Clob>
      Overrides:
      extractHashCode in class AbstractClassJavaType<Clob>
      Parameters:
      value - The value for which to extract a hash code.
      Returns:
      The extracted hash code.

    • areEqual

      public boolean areEqual(Clob one, Clob another)
      Description copied from interface: JavaType
      Determine if two instances are equal
      Specified by:
      areEqual in interface JavaType<Clob>
      Overrides:
      areEqual in class AbstractClassJavaType<Clob>
      Parameters:
      one - One instance
      another - The other instance
      Returns:
      True if the two are considered equal; false otherwise.

    • getReplacement

      public Clob getReplacement(Clob original, Clob target, SharedSessionContractImplementor session)

    • unwrap

      public <X> X unwrap(Clob 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 the Integer value as a Long, we would return something like Long.valueOf( value.longValue() ).

      Intended use is during PreparedStatement binding.

      Type Parameters:
      X - The conversion type.
      Parameters:
      value - The value to unwrap
      type - The type as which to unwrap
      options - The options
      Returns:
      The unwrapped value.

    • wrap

      public <X> Clob 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.

    • getDefaultSqlLength

      public long getDefaultSqlLength(Dialect dialect, JdbcType jdbcType)
      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 example Types.VARCHAR.
      Returns:
      Size.DEFAULT_LENGTH unless overridden
