  • Method Details

    • underscoreAware

      public static jakarta.persistence.Tuple underscoreAware(jakarta.persistence.Tuple delegate)
      Creates a underscore-aware Tuple wrapper applying JdbcUtils.convertPropertyNameToUnderscoreName(java.lang.String) conversion to leniently look up properties from query results whose columns follow snake-case syntax.
      Parameters:
      delegate - the tuple to wrap.
      Returns:

    • size

      public int size()
      Specified by:
      size in interface Map<String,Object>

    • isEmpty

      public boolean isEmpty()
      Specified by:
      isEmpty in interface Map<String,Object>

    • containsKey

      public boolean containsKey(Object key)
      If the key is not a String or not a key of the backing Tuple this returns false. Otherwise this returns true even when the value from the backing Tuple is null.
      Specified by:
      containsKey in interface Map<String,Object>
      Parameters:
      key - the key for which to get the value from the map.
      Returns:
      whether the key is an element of the backing tuple.

    • containsValue

      public boolean containsValue(Object value)
      Specified by:
      containsValue in interface Map<String,Object>

    • get

      public @Nullable Object get(Object key)
      If the key is not a String or not a key of the backing Tuple this returns null. Otherwise the value from the backing Tuple is returned, which also might be null.
      Specified by:
      get in interface Map<String,Object>
      Parameters:
      key - the key for which to get the value from the map.
      Returns:
      the value of the backing Tuple for that key or null.
