Method Detail

get

String get(int segmentNumber)

Get a particular segment within this path.

Parameters:

segmentNumber - the 0-based index of the segment in this path

Returns:

the segment; never null

Throws:

IndexOutOfBoundsException - if the segment number is negative, or greater than or equal to the size.

getLast

String getLast()

Get the last segment in the path.

Returns:

the field name in the last segment of this path, or null if this is the empty path

getFirst

String getFirst()

Get the first segment in the path.

Returns:

the field name in the first segment of this path, or null if this is the empty path

size

int size()

Get the number of segments in this path. An empty path with have a size of '0'.

Returns:

the size of this path; never negative

with

Path with(String fieldName)

Obtain a path that has this path as the parent and which has as the last segment the supplied field name.

Parameters:

fieldName - the field name for the last segment in the new path; may be null

Returns:

the new path, or this path if the fieldName parameter is null; never null

parent

Path parent()

Get the parent path, which may be an empty path.

Returns:

the parent path; never null

startsWith

boolean startsWith(Path other)

Determine if the first segments of this path are equal to the segments in the supplied path. This method returns true if the two paths are equal, or if the supplied path is an ancestor of this path.

Parameters:

other - the other path; may not be null

Returns:

true if the other path is equal to or an ancestor of this path, or false otherwise
