An interface to associate implict contexts with communicators. When you make a remote invocation without an explicit Ice::Context parameter, Ice uses the per-proxy Ice::Context (if any) combined with the ImplicitContext
associated with the communicator.
Ice provides several implementations of ImplicitContext
. The implementation used depends on the value of the Ice.ImplicitContext
property.
None
(default) — No implicit context at all.
PerThread
— The implementation maintains a Ice::Context per thread.
Shared
— The implementation maintains a single Ice::Context shared by all threads.
ImplicitContext
also provides a number of operations to create, update or retrieve an entry in the underlying context without first retrieving a copy of the entire context. These operations correspond to a subset of the java.util.Map
methods, with java.lang.Object
replaced by string
and null replaced by the empty-string.
getContext — Get a copy of the underlying context.
setContext — Set the underlying context.
containsKey — Check if this key has an associated value in the underlying context.
get — Get the value associated with the given key in the underlying context.
put — Create or update a key/value entry in the underlying context.
remove — Remove the entry for the given key in the underlying context.
Get a copy of the underlying context.
A copy of the underlying context.
Set the underlying context.
newContext
— The new context.
Check if this key has an associated value in the underlying context.
key
— The key.
True if the key has an associated value, False otherwise.
Get the value associated with the given key in the underlying context. Returns an empty string if no value is associated with the key. containsKey allows you to distinguish between an empty-string value and no value at all.
key
— The key.
The value associated with the key.
Create or update a key/value entry in the underlying context.
key
— The key.
value
— The value.
The previous value associated with the key, if any.
Remove the entry for the given key in the underlying context.
key
— The key.
The value associated with the key, if any.
