Ice provides convenient interfaces for streaming Slice types to and from a sequence of bytes. You can use these interfaces in many situations, such as when serializing types for persistent storage, and when using Ice's dynamic invocation and dispatch facility.
The streaming interfaces are not defined in Slice, but are rather a collection of native classes provided by each language mapping.
There are two primary abstract classes:
OutputStream. As you might guess,
InputStream is used to extract Slice types from a sequence of bytes, while
OutputStream is used to convert Slice types into a sequence of bytes. The classes provide the functions necessary to manipulate all of the core Slice types:
- Primitives (
- Sequences of primitives
The classes also provide functions that handle various details of the Ice encoding. Using these functions, you can manually insert and extract constructed types, such as dictionaries and structures, but doing so is tedious and error-prone. To make insertion and extraction of constructed types easier, the Slice compilers generate type-specific code that manages the low-level details for you.
The remainder of this section describes the streaming interfaces for each supported language mapping. To properly use the streaming interfaces, you should be familiar with the Ice encoding. For an example that demonstrates the use of the streaming interfaces, refer to the
Ice/invoke directory in the Ice demo distribution.
