== Types

[cols="1,4"]
|===
| Name| Description
| xref:BloombergLP/bslx/ByteInStream.adoc[`ByteInStream`] 
| Provide a BDEX input stream that unexternalizes values from a byte buffer.
| xref:BloombergLP/bslx/ByteOutStream.adoc[`ByteOutStream`] 
| Provide a BDEX output stream that externalizes values to a byte buffer.
| xref:BloombergLP/bslx/GenericInStream.adoc[`GenericInStream`] 
| Parameterized input stream for unexternalizing fundamental types.
| xref:BloombergLP/bslx/GenericOutStream.adoc[`GenericOutStream`] 
| Provide a BDEX output stream that externalizes values to a stream buffer.
| xref:BloombergLP/bslx/MarshallingUtil.adoc[`MarshallingUtil`] 
| Provide utilities for marshalling fundamental types in network byte order.
| xref:BloombergLP/bslx/TestInStream.adoc[`TestInStream`] 
| This class provides a test input stream for BDEX unexternalization.
| xref:BloombergLP/bslx/TestInStreamException.adoc[`TestInStreamException`] 
| This class defines an exception object for unexternalization operations. Instances of this class contain information about an unexternalization request.
| xref:BloombergLP/bslx/TestInStream_Proxy.adoc[`TestInStream_Proxy`] 
| Proxy for a test stream used by the exception‐test macros.
| xref:BloombergLP/bslx/TestInStream_ProxyBase.adoc[`TestInStream_ProxyBase`] 
| Common base class for `TestInStream_Proxy`.
| xref:BloombergLP/bslx/TestOutStream.adoc[`TestOutStream`] 
| This class implements a test output stream for BDEX externalization.
| xref:BloombergLP/bslx/TypeCode.adoc[`TypeCode`] 
| This `struct` provides a namespace for enumerating the set of fundamental types supported within `bslx`. See `Enum` in the `TYPES` sub‐section for details.
| xref:BloombergLP/bslx/VersionFunctions_DoesNotHaveBdexVersion.adoc[`VersionFunctions_DoesNotHaveBdexVersion`] 
| Tag type for overload resolution of types without BDEX versions.
| xref:BloombergLP/bslx/VersionFunctions_HasBdexVersion.adoc[`VersionFunctions_HasBdexVersion`] 
| This class is used to perform function overload resolution for types that _have_ BDEX versions. This class contains no interface or implementation by design.
| xref:BloombergLP/bslx/VersionFunctions_NonFundamentalImpl-0b.adoc[`VersionFunctions_NonFundamentalImpl`] 
| Namespace for BDEX version queries on non‐fundamental types.
|===


== Type Aliases

[cols="1,4"]
|===
| Name| Description
| xref:BloombergLP/bslx/StreambufInStream.adoc[`StreambufInStream`] 
| Input stream that unexternalizes fundamental types from a `bsl::streambuf`.
| xref:BloombergLP/bslx/StreambufOutStream.adoc[`StreambufOutStream`] 
| Provide a BDEX output stream that externalizes values to a `bsl::streambuf`.
|===


== Functions

[cols="1,4"]
|===
| Name| Description
| xref:BloombergLP/bslx/TestInStream_getProxy.adoc[`TestInStream_getProxy`] 
| Return, by value, a test stream proxy for the specified parameterized `stream`.
| xref:BloombergLP/bslx/operator_rshift-03a.adoc[`operator>>`] 
| Right shift operators
| xref:BloombergLP/bslx/operator_lshift-0b.adoc[`operator<<`] 
| Stream insertion operators
