Interface JavaTypeResolver

All Known Implementing Classes:
JavaTypeResolverDefaultImpl
public interface JavaTypeResolver
This interface describes methods that are required in any Java type resolver. A Java type resolver is used to make a default translation between a JDBC type as returned from the database introspection process, and a Java type.

    Method
    Description
    void
    addConfigurationProperties(Properties properties)
    Adds properties for this instance from any properties configured in the JavaTypeResolverConfiguration.
    FullyQualifiedJavaType
    calculateJavaType(IntrospectedColumn introspectedColumn)
    Calculates and returns the Java type that should be associated with this column based on the jdbc type, length, and scale of the column.
    String
    calculateJdbcTypeName(IntrospectedColumn introspectedColumn)
    Calculates and returns the JDBC type name that should be associated with this column based on the jdbc type, length, and scale of the column.
    void
    setContext(Context context)
    Sets the instance of the Context object associated with this instance.
    void
    setWarnings(List<String> warnings)
    The generator will supply a list to this method.

  • Method Details

    • addConfigurationProperties

      void addConfigurationProperties(Properties properties)
      Adds properties for this instance from any properties configured in the JavaTypeResolverConfiguration.

      This method will be called before any of the get methods.

      Parameters:
      properties - All properties from the configuration

    • setContext

      void setContext(Context context)
      Sets the instance of the Context object associated with this instance.

      This method will be called before any of the get methods.

      Parameters:
      context - The current Context

    • setWarnings

      void setWarnings(List<String> warnings)
      The generator will supply a list to this method. The implementation class may add strings to the list that will be treated as warning messages and displayed to the user. The concept of a warning is that code generation can continue, but that the results may not be what is expected.
      Parameters:
      warnings - the new warnings

    • calculateJavaType

      FullyQualifiedJavaType calculateJavaType(IntrospectedColumn introspectedColumn)
      Calculates and returns the Java type that should be associated with this column based on the jdbc type, length, and scale of the column.
      Parameters:
      introspectedColumn - the column whose Java type needs to be calculated
      Returns:
      the calculated type, or null if an unsupported data type. If null is returned, we will set the type to Object and issue a warning unless the column is ignored or otherwise overridden

    • calculateJdbcTypeName

      String calculateJdbcTypeName(IntrospectedColumn introspectedColumn)
      Calculates and returns the JDBC type name that should be associated with this column based on the jdbc type, length, and scale of the column.
      Parameters:
      introspectedColumn - the column whose Java type needs to be calculated
      Returns:
      the calculated type name, or null if an unsupported data type. If null is returned, we will set the type to OTHER and issue a warning unless the column is ignored or otherwise overridden
