Method Details

isExplicitURLResource

public static boolean isExplicitURLResource(@Nullable
 String sName)

Check if the passed resource name is an explicit URL resource.

Parameters:

sName - The name to check. May be null.

Returns:

true if the passed name is an explicit URL resource.

getResourceID

@Nonnull
public String getResourceID()

Specified by:

getResourceID in interface IResourceBase

Returns:

A non-null resource ID used e.g. for system IDs in XML resolving.

getPath

@Nonnull
public String getPath()

Specified by:

getPath in interface IResourceBase

Returns:

The requested path. Never null

getInputStream

@Nullable
public static InputStream getInputStream(@Nonnull
 URL aURL)

getInputStream

@Nullable
public InputStream getInputStream()

Description copied from interface: IHasInputStream

Get the input stream to read from the object. Each time this method is called, a new InputStream needs to be created.

Specified by:

getInputStream in interface IHasInputStream

Returns:

null if resolving failed.

getInputStream

@Nullable
public InputStream getInputStream(@CheckForSigned
 int nConnectTimeoutMS,
 @CheckForSigned
 int nReadTimeoutMS)

 IMutableWrapper<IOException> aExceptionHolder)

getInputStream

@Nullable
public InputStream getInputStream(@CheckForSigned
 int nConnectTimeoutMS,
 @CheckForSigned
 int nReadTimeoutMS,
 @Nullable
 IMutableWrapper<IOException> aExceptionHolder)

getInputStream

@Nullable
public InputStream getInputStream(@CheckForSigned
 int nConnectTimeoutMS,
 @CheckForSigned
 int nReadTimeoutMS,
 @Nullable
 Consumer<? super URLConnection> aConnectionModifier,
 @Nullable
 IMutableWrapper<IOException> aExceptionHolder)

isReadMultiple

public final boolean isReadMultiple()

Description copied from interface: IHasInputStream

Check if the InputStream from IHasInputStream.getInputStream() and IHasInputStream.getBufferedInputStream() can be acquired more than once.

Specified by:

isReadMultiple in interface IHasInputStream

Returns:

true if the input stream can be acquired more than once, false if not.

exists

public boolean exists()

Specified by:

exists in interface IResourceBase

Returns:

true if the resource exists, false otherwise.

getAsURL

@Nonnull
public URL getAsURL()

Specified by:

getAsURL in interface IResourceBase

Returns:

the URL representation of this resource. May be null if this resource cannot be represented as an URL.

getAsURI

@Nullable
public URI getAsURI()

getAsFile

@Nullable
public File getAsFile()

Specified by:

getAsFile in interface IResourceBase

Returns:

the File representation of this resource. May be null if this resource cannot be represented as a file.

getReadableCloneForPath

@Nonnull
public URLResource getReadableCloneForPath(@Nonnull
 URL aURL)

getReadableCloneForPath

@Nonnull
public URLResource getReadableCloneForPath(@Nonnull
 String sPath)

Description copied from interface: IReadableResource

Get a new resource of the same implementation type as this object but for a different path.

Specified by:

getReadableCloneForPath in interface IReadableResource

Parameters:

sPath - The new path to use. May not be null.

Returns:

The resource of the same implementation but a different path. May not be null.
