Creates a wrapper for a Source which ensures that Source.getLastModified() won't be called more than once per delay milliseconds period.

Parameters:

source - the wrapped Source

delay - the last-modified refresh delay, in milliseconds

Method Detail

getLastModified

public final long getLastModified()

Deprecated.

Get the last modification time for the wrapped Source. The age of the returned information is guaranteed to be lower than or equal to the delay specified in the constructor.

This method is also thread-safe, even if the underlying Source is not.

Specified by:

getLastModified in interface Source

Returns:

the last modification time.

refresh

public final void refresh()

Deprecated.

Force the refresh of the wrapped Source, even if the refresh period isn't over, and starts a new period.

This method is thread-safe, even if the underlying Source is not.

Specified by:

refresh in interface ModifiableSource

getContentLength

public final long getContentLength()

Deprecated.

Description copied from interface: Source

Get the content length of the source or -1 if it is not possible to determine the length.

Specified by:
