Interface MapElementView<T>

Type Parameters:
T - the type of element that this handles.
public interface MapElementView<T>
This class provides a means for reading map data in a data- or implementation-agnostic way. Each of the methods take an arbitrary field type enumeration. Each implementation of this view should be clear as to what those valid values are.

    • getValue

      Object getValue(T source, int fieldType)
      Gets the corresponding value on the element. If the field type is not valid for this element, this returns null.
      Parameters:
      source - the source object.
      fieldType - the field type to retrieve.
      Returns:
      the corresponding value or null if the field type is not valid.

    • getBoolean

      default Boolean getBoolean(T source, int fieldType)
      Gets the corresponding value on the element as a boolean. If the field type is not valid for this element, this returns null. Numeric values return true if nonzero, and String values are true if they are not blank.
      Parameters:
      source - the source object.
      fieldType - the field type to retrieve.
      Returns:
      the corresponding value or null if the field type is not valid.

    • getBoolean

      default boolean getBoolean(T source, int fieldType, boolean def)
      Gets the corresponding value on the element as a boolean. If the field type is not valid for this element, this returns def. Numeric values return true if nonzero, and String values are true if they are not blank.
      Parameters:
      source - the source object.
      fieldType - the field type to retrieve.
      def - the default value to return if the field type is not valid.
      Returns:
      the corresponding value or def if the field type is not valid.

    • getInteger

      default Integer getInteger(T source, int fieldType)
      Gets the corresponding value on the element as an integer. If the field type is not valid for this element, this returns null. Boolean values return 1 if true, and String values are converted to integer (or null if not convertible).
      Parameters:
      source - the source object.
      fieldType - the field type to retrieve.
      Returns:
      the corresponding value or null if the field type is not valid.

    • getInteger

      default int getInteger(T source, int fieldType, int def)
      Gets the corresponding value on the element as an integer. If the field type is not valid for this element, this returns def. Boolean values return 1 if true 0 if false, and String values are converted to integer (or def if not convertible).
      Parameters:
      source - the source object.
      fieldType - the field type to retrieve.
      def - the default value to return if the field type is not valid.
      Returns:
      the corresponding value or def if the field type is not valid.

    • getFloat

      default Float getFloat(T source, int fieldType)
      Gets the corresponding value on the element as a float. If the field type is not valid for this element, this returns null. Boolean values return 1f if true, 0f if false, and String values are converted to float (or null if not convertible).
      Parameters:
      source - the source object.
      fieldType - the field type to retrieve.
      Returns:
      the corresponding value or null if the field type is not valid.

    • getFloat

      default float getFloat(T source, int fieldType, float def)
