Method Detail

getDataPath

public java.lang.String getDataPath()

Description copied from interface: RelativePathResolver

Gets the data path used to resolve relative paths. More than one directory may be specified by separating them with the System path.separator character (; on windows, : on UNIX). Elements of this path may be absolute or relative file paths.

Specified by:

getDataPath in interface RelativePathResolver

Returns:

the data path

See Also:

RelativePathResolver.getDataPath()

setDataPath

public void setDataPath(java.lang.String aPath)
                 throws java.net.MalformedURLException

Description copied from interface: RelativePathResolver

Sets the data path used to resolve relative paths. More than one directory may be specified by separating them with the System path.separator character (; on windows, : on UNIX). Elements of this path may be absolute or relative file paths.

Specified by:

setDataPath in interface RelativePathResolver

Parameters:

aPath - the data path

Throws:

java.net.MalformedURLException - if a file path could not be converted to a URL

See Also:

RelativePathResolver.setDataPath(java.lang.String)

resolveRelativePath

public java.net.URL resolveRelativePath(java.net.URL aRelativeUrl)

Description copied from interface: RelativePathResolver

Resolves a relative URL to an absolute URL. This will attempt to resolve the URL relative to each element of the data path, sequentially starting with the first element. If this results in an absolute URL at which a file actually exists, that absolute URL is returned. If no file could be found, null is returned.

Specified by:

resolveRelativePath in interface RelativePathResolver

Parameters:

aRelativeUrl - the relative URL to be resolved (if an absolute URL is specified, it will be returned unmodified if a file actually exists at the URL; otherwise null will be returned).

Returns:

the absolute URL at which the file exists, null it none could be found.

See Also:

RelativePathResolver.resolveRelativePath(java.net.URL)

setPathResolverClassLoader

public void setPathResolverClassLoader(java.lang.ClassLoader aClassLoader)

Description copied from interface: RelativePathResolver

Sets the ClassLoader that should be used to resolve the resources.

Specified by:

setPathResolverClassLoader in interface RelativePathResolver

Parameters:

aClassLoader - the ClassLoader that should be used to resolve the resources.

See Also:

RelativePathResolver.setPathResolverClassLoader(java.lang.ClassLoader)

fileExistsAtUrl

protected boolean fileExistsAtUrl(java.net.URL aUrl)

Utility method that checks to see if a file exists at the specified URL.

getBaseUrls

protected java.net.URL[] getBaseUrls()

Gets the base URLs that were parsed from the data path.
