    • addNativeTypeMapping

      public void addNativeTypeMapping(int jdbcTypeCode, String nativeType)
      Adds a mapping from jdbc type to database-native type.
      Parameters:
      jdbcTypeCode - The jdbc type code as defined by Types
      nativeType - The native type

    • addNativeTypeMapping

      public void addNativeTypeMapping(int jdbcTypeCode, String nativeType, int targetJdbcTypeCode)
      Adds a mapping from jdbc type to database-native type.
      Parameters:
      jdbcTypeCode - The jdbc type code as defined by Types
      nativeType - The native type
      targetJdbcTypeCode - The jdbc type code corresponding to the native type (e.g. when reading the model from the database)

    • addNativeTypeMapping

      public void addNativeTypeMapping(String jdbcTypeName, String nativeType)
      Adds a mapping from jdbc type to database-native type. Note that this method accesses the named constant in Types via reflection and is thus safe to use under JDK 1.2/1.3 even with constants defined only in later Java versions - for these, the method simply will not add a mapping.
      Parameters:
      jdbcTypeName - The jdbc type name, one of the constants defined in Types
      nativeType - The native type

    • addNativeTypeMapping

      public void addNativeTypeMapping(String jdbcTypeName, String nativeType, String targetJdbcTypeName)
      Adds a mapping from jdbc type to database-native type. Note that this method accesses the named constant in Types via reflection and is thus safe to use under JDK 1.2/1.3 even with constants defined only in later Java versions - for these, the method simply will not add a mapping.
      Parameters:
      jdbcTypeName - The jdbc type name, one of the constants defined in Types
      nativeType - The native type
      targetJdbcTypeName - The jdbc type corresponding to the native type (e.g. when reading the model from the database)

    • hasNullDefault

      public boolean hasNullDefault(int sqlTypeCode)

      Returns:
      true if the native type has a null default value

    • setHasNullDefault

      public void setHasNullDefault(int sqlTypeCode, boolean hasNullDefault)
      Specifies whether the native type for the given sql type code (one of the Types constants) has a null default value on this platform.
      Parameters:
      sqlTypeCode - The sql type code
      hasNullDefault - true if the native type has a null default value

    • hasSize

      Parameters:
      sqlTypeCode - The sql type code
      Returns:
      true if the native type has a size specification

    • setHasSize

      public void setHasSize(int sqlTypeCode, boolean hasSize)
      Specifies whether the native type for the given sql type code (one of the Types constants) has a size specification on this platform.
      Parameters:
      sqlTypeCode - The sql type code
      hasSize - true if the native type has a size specification

    • getDefaultSize

      public Integer getDefaultSize(int jdbcTypeCode)
      Returns the default size value for the given type, if any.
      Parameters:

      Returns:
      The default size or null if none is defined

    • setDefaultSize

      public void setDefaultSize(int jdbcTypeCode, int defaultSize)
      Adds a default size for the given jdbc type.
      Parameters:
      jdbcTypeCode - The jdbc type code
      defaultSize - The default size

    • setDefaultSize

      public void setDefaultSize(String jdbcTypeName, int defaultSize)

    • hasPrecisionAndScale

      public boolean hasPrecisionAndScale(int sqlTypeCode)
