In the call graph viewer below, each node
|
|
is a function belonging to this package
|
|
and its children are the functions it
|
|
calls—perhaps dynamically.
|
|
</p>
|
|
<p>
|
|
The root nodes are the entry points of the
|
|
package: functions that may be called from
|
|
outside the package.
|
|
There may be non-exported or anonymous
|
|
functions among them if they are called
|
|
dynamically from another package.
|
|
</p>
|
|
<p>
|
|
Click a node to visit that function's source code.
|
|
From there you can visit its callers by
|
|
clicking its declaring <code>func</code>
|
|
token.
|
|
</p>
|
|
<p>
|
|
Functions may be omitted if they were
|
|
determined to be unreachable in the
|
|
particular programs or tests that were
|
|
analyzed.

<pre>type LruCache struct {

|
|
<p>
|
|
LruCache is a thread-safe, in-memory httpcache.Cache that evicts the
|
|
least recently used entries from memory when either MaxSize (in bytes)
|
|
limit would be exceeded or (if set) the entries are older than MaxAge (in
|
|
seconds). Use the New constructor to create one.

|
|
<p>
|
|
New creates an LruCache that will restrict itself to maxSize bytes of
|
|
memory. If maxAge > 0, entries will also be expired after maxAge
|
|
seconds.

Get returns the []byte representation of a cached response and a bool
