Method Detail

schemeWalk

public Path schemeWalk(java.lang.String userPath,
                       java.util.Map<java.lang.String,java.lang.Object> attributes,
                       java.lang.String path,
                       int offset)

Description copied from class: Path

Path-specific lookup. Path implementations will override this.

Specified by:

schemeWalk in class Path

Parameters:

userPath - the user's lookup() path.

attributes - the attributes for the new path.

path - the lookup() path

offset - offset into newPath to start lookup.

Returns:

the found path

getURL

public java.lang.String getURL()

Description copied from class: Path

Returns the full url for the given path.

Overrides:

getURL in class Path

getScheme

public java.lang.String getScheme()

Description copied from class: Path

Returns the url scheme

Specified by:

getScheme in class Path

getPath

public java.lang.String getPath()

Description copied from class: Path

Returns the path. e.g. for HTTP, returns the part after the host and port.

Specified by:

getPath in class Path

lookupImpl

public Path lookupImpl(java.lang.String userPath,
                       java.util.Map<java.lang.String,java.lang.Object> newAttributes)

Description copied from class: Path

Returns a new path relative to the current one.

Path only handles scheme:xxx. Subclasses of Path will specialize the xxx.

Overrides:

lookupImpl in class Path

Parameters:

userPath - relative or absolute path, essentially any url.

newAttributes - attributes for the new path.

Returns:

the new path or null if the scheme doesn't exist
