      Return the actual property name for the given property path.
      static boolean isNestedOrIndexedProperty(java.lang.String propertyPath)
      Check whether the given property path indicates an indexed or nested property.
      static boolean matchesProperty(java.lang.String registeredPath, java.lang.String propertyPath)
      Determine whether the given registered path matches the given property path, either indicating the property itself or an indexed element of the property.

      • getPropertyName

        public static java.lang.String getPropertyName(java.lang.String propertyPath)
        Return the actual property name for the given property path.
        Parameters:
        propertyPath - the property path to determine the property name for (can include property keys, for example for specifying a map entry)
        Returns:
        the actual property name, without any key elements
      • isNestedOrIndexedProperty

        public static boolean isNestedOrIndexedProperty(@Nullable
                                                        java.lang.String propertyPath)
        Check whether the given property path indicates an indexed or nested property.
        Parameters:
        propertyPath - the property path to check
        Returns:
        whether the path indicates an indexed or nested property
      • getFirstNestedPropertySeparatorIndex

        public static int getFirstNestedPropertySeparatorIndex(java.lang.String propertyPath)
        Determine the first nested property separator in the given property path, ignoring dots in keys (like "map[my.key]").
        Parameters:
        propertyPath - the property path to check
        Returns:
        the index of the nested property separator, or -1 if none
      • getLastNestedPropertySeparatorIndex

        public static int getLastNestedPropertySeparatorIndex(java.lang.String propertyPath)
        Determine the first nested property separator in the given property path, ignoring dots in keys (like "map[my.key]").
        Parameters:
        propertyPath - the property path to check
        Returns:
        the index of the nested property separator, or -1 if none
      • matchesProperty

        public static boolean matchesProperty(java.lang.String registeredPath,
                                              java.lang.String propertyPath)
        Determine whether the given registered path matches the given property path, either indicating the property itself or an indexed element of the property.
        Parameters:
        propertyPath - the property path (typically without index)
        registeredPath - the registered path (potentially with index)
        Returns:
        whether the paths match
      • canonicalPropertyName

        public static java.lang.String canonicalPropertyName(@Nullable
                                                             java.lang.String propertyName)
        Determine the canonical name for the given property path. Removes surrounding quotes from map keys:
        map['key'] -> map[key]
        map["key"] -> map[key]
        Parameters:
        propertyName - the bean property path
        Returns:
        the canonical representation of the property path
      • canonicalPropertyNames

        @Nullable
        public static java.lang.String[] canonicalPropertyNames(@Nullable
                                                                          java.lang.String[] propertyNames)
        Determine the canonical names for the given property paths.
        Parameters:
        propertyNames - the bean property paths (as array)
        Returns:
        the canonical representation of the property paths (as array of the same size)
