Detailed Description

A least-recently-used cache bounded by the summed size in bytes of its values, not by their number (the former thumbnail cache counted one unit per bitmap against a byte-sized limit, so it never evicted in practice).

Thread safe; no Android classes, so the sizing function is passed in.

Member Function Documentation

put()

synchronized void de.yaacc.util.image.ByteLruCache< K, V >.put	(	K	key,
		V	value )

Stores the value as the most recently used one and evicts the least recently used ones until the limit holds.

A value larger than the whole cache is not stored (and an older value for the key is dropped).
