Method Details

isCached

public boolean isCached()

Description copied from interface: Seekable

Returns true if this Seekable stream caches data itself in order to allow seeking backwards. Applications may consult this in order to decide how frequently, or whether, to flush in order to conserve cache resources.

Returns:

true if this Seekable caches data.

See Also:

• Seekable.isCachedMemory()
• Seekable.isCachedFile()

isCachedFile

public boolean isCachedFile()

Description copied from interface: Seekable

Returns true if this Seekable stream caches data itself in order to allow seeking backwards, and the cache is kept in a temporary file. Applications may consult this in order to decide how frequently, or whether, to flush in order to conserve cache resources.

Returns:

true if this Seekable caches data in a temporary file.

See Also:

• Seekable.isCached()
• Seekable.isCachedMemory()

isCachedMemory

public boolean isCachedMemory()

Description copied from interface: Seekable

Returns true if this Seekable stream caches data itself in order to allow seeking backwards, and the cache is kept in main memory. Applications may consult this in order to decide how frequently, or whether, to flush in order to conserve cache resources.

Returns:

true if this Seekable caches data in main memory.
