Enum Class DefaultSqlSerializationContext

java.lang.Object
java.lang.Enum<DefaultSqlSerializationContext>
org.postgresql.core.v3.DefaultSqlSerializationContext
All Implemented Interfaces:
Serializable, Comparable<DefaultSqlSerializationContext>, Constable, SqlSerializationContext
enum DefaultSqlSerializationContext extends Enum<DefaultSqlSerializationContext> implements SqlSerializationContext
Provides a default implementation for SqlSerializationContext.

  • Enum Constant Details

    • STDSTR_IDEMPOTENT

      public static final DefaultSqlSerializationContext STDSTR_IDEMPOTENT
      Render SQL in a repeatable way (avoid consuming InputStream sources), use standard_conforming_strings=yes string literals. This option is useful for toString() implementations as it does induce side effects.

    • STDSTR_NONIDEMPOTENT

      public static final DefaultSqlSerializationContext STDSTR_NONIDEMPOTENT
      Render SQL with replacing all the parameters, including InputStream sources. Use standard_conforming_strings=yes for string literals. This option is useful for rendering an executable SQL.

    • NONSTDSTR_IDEMPOTENT

      public static final DefaultSqlSerializationContext NONSTDSTR_IDEMPOTENT
      Render SQL in a repeatable way (avoid consuming InputStream sources), use standard_conforming_strings=no string literals. The entry is for completeness only as standard_conforming_strings=no should probably be avoided.

    • NONSTDSTR_NONIDEMPOTENT

      public static final DefaultSqlSerializationContext NONSTDSTR_NONIDEMPOTENT
      Render SQL with replacing all the parameters, including InputStream sources. Use standard_conforming_strings=no for string literals. The entry is for completeness only as standard_conforming_strings=no should probably be avoided.

  • Field Details

    • standardConformingStrings

      private final boolean standardConformingStrings

    • idempotent

      private final boolean idempotent

  • Constructor Details

    • DefaultSqlSerializationContext

      private DefaultSqlSerializationContext(boolean standardConformingStrings, boolean idempotent)

  • Method Details

    • values

      public static DefaultSqlSerializationContext[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static DefaultSqlSerializationContext valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null

    • getStandardConformingStrings

      public boolean getStandardConformingStrings()
      Description copied from interface: SqlSerializationContext
      Returns true if strings literals should use standard_conforming_strings=on encoding.
      Specified by:
      getStandardConformingStrings in interface SqlSerializationContext
      Returns:
      true if strings literals should use standard_conforming_strings=on encoding.

    • getIdempotent

      public boolean getIdempotent()
      Description copied from interface: SqlSerializationContext
      Returns true if the SQL to String conversion should be idempotent. For instance, if a query parameter comes from an InputStream, then the stream could be skipped when writing SQL with idempotent mode.
      Specified by:
      getIdempotent in interface SqlSerializationContext
      Returns:
      true if the SQL to String conversion should be idempotent
