| Method Summary | |
| public static String | buildPath(String[] segments)
Builds an EL path of from an array of path segments. | | public static String | buildPath(String[] segments, int start, int finish)
Builds an EL path of variable length, from a subsection of an array of
segments. | | public static String | buildPath(String prefix, String suffix)
Compose a prefix and suffix EL path, where the prefix has not been escaped,
and is not null.
Parameters:
prefix - A single path segment (bean name) starting the path, may notbe null or empty. | | public static String | composePath(String prefix, String suffix)
Compose a prefix and suffix EL path, where the prefix is already escaped.
Prefix may be empty, but not null. | | public static String | composePathEncoded(String head, String tail)
| | static void | composeSegment(CharWrap toaccept, String toappend)
| | public static String | getFromHeadPath(String path)
| | public static String | getHeadPath(String path)
| | public static String | getHeadPathEncoded(String path)
| | static String | getPathSegment(String path, int i)
| | static int | getPathSegment(CharWrap accept, String path, int i)
| | public static String | getTailPath(String path)
| | public static String | getToTailPath(String path)
| | static int | lastDotIndex(String path)
| | public static String[] | splitPath(String path)
|
| buildPath | | public static String buildPath(String[] segments)(Code) | | Builds an EL path of from an array of path segments. Particulary good when using
Strings of BeanLocators, Maps, and friends. Assumes none of the segments
have been escaped yet.
|
| buildPath | | public static String buildPath(String[] segments, int start, int finish)(Code) | | Builds an EL path of variable length, from a subsection of an array of
segments.
|
| buildPath | | public static String buildPath(String prefix, String suffix)(Code) | | Compose a prefix and suffix EL path, where the prefix has not been escaped,
and is not null.
Parameters:
prefix - A single path segment (bean name) starting the path, may notbe null or empty. This will become escaped.
Parameters:
suffix - A single path segment (property name) continuing the path,may not be null or empty. This will become escaped. A properly escaped full path, representing "prefix.suffix". |
| composePath | | public static String composePath(String prefix, String suffix)(Code) | | Compose a prefix and suffix EL path, where the prefix is already escaped.
Prefix may be empty, but not null. The suffix will become escaped.
|
| composePathEncoded | | public static String composePathEncoded(String head, String tail)(Code) | | Compose head and tail paths, where escaping is unnecessary *
|
| getHeadPathEncoded | | public static String getHeadPathEncoded(String path)(Code) | | Returns the first path segment, without performing unescaping *
|
| getTailPath | | public static String getTailPath(String path)(Code) | | Returns the very last path component of a bean path
|
| splitPath | | public static String[] splitPath(String path)(Code) | | Parses a path into an array of decoded EL segments *
