isCached
public boolean isCached()
Description copied from interface:Seekable
Returns true if thisSeekable
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 thisSeekable
caches data.- See Also:
Seekable.isCachedMemory()
,Seekable.isCachedFile()
-
isCachedFile
public boolean isCachedFile()
Description copied from interface:Seekable
Returns true if thisSeekable
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 thisSeekable
caches data in a temporary file.- See Also:
Seekable.isCached()
,Seekable.isCachedMemory()
-
isCachedMemory
public boolean isCachedMemory()
Description copied from interface:Seekable
Returns true if thisSeekable
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 thisSeekable
caches data in main memory.- See Also:
