Abstraction and base class for stream-based protocols.
</brief_description>
<description>
StreamPeer is an abstraction and base class for stream-based protocols (such as TCP or Unix Sockets). It provides an API for sending and receiving data through streams as raw data or strings.

</description>
</method>
<method name="get_available_bytes" qualifiers="const">
<return type="int">
</return>
<description>
Return the amount of bytes this [code]StreamPeer[/code] has available.
</description>
</method>
<method name="get_data">
<return type="Array">
</return>
<argument index="0" name="bytes" type="int">
</argument>
<description>
Return a chunk data with the received bytes. The amount of bytes to be received can be requested in the "bytes" argument. If not enough bytes are available, the function will block until the desired amount is received. This function returns two values, an Error code and a data array.
</description>
</method>
<method name="get_double">
<return type="float">
</return>
<description>
Get a double-precision float from the stream.

</return>
<description>
Get a single-precision float from the stream.
</description>
</method>
<method name="get_partial_data">
<return type="Array">
</return>
<argument index="0" name="bytes" type="int">
</argument>
<description>
Return a chunk data with the received bytes. The amount of bytes to be received can be requested in the "bytes" argument. If not enough bytes are available, the function will return how many were actually received. This function returns two values, an Error code, and a data array.
</description>
</method>
<method name="get_string">
<return type="String">
</return>
<argument index="0" name="bytes" type="int" default="-1">
</argument>
<description>
Get a string with byte-length [code]bytes[/code] from the stream. If [code]bytes[/code] is negative (default) the length will be read from the stream using the reverse process of [method put_string].

<description>
Get an unsigned 16 bit value from the stream.

Get an unsigned byte from the stream.
</description>
</method>
<method name="get_utf8_string">
<return type="String">
</return>
<argument index="0" name="bytes" type="int" default="-1">
</argument>
<description>
Get a utf8 string with byte-length [code]bytes[/code] from the stream (this decodes the string sent as utf8). If [code]bytes[/code] is negative (default) the length will be read from the stream using the reverse process of [method put_utf8_string].
</description>
</method>
<method name="get_var">
<return type="Variant">
</return>
<argument index="0" name="allow_objects" type="bool" default="false">

<description>
Get a Variant from the stream. When [code]allow_objects[/code] is [code]true[/code] decoding objects is allowed.
[b]WARNING:[/b] Deserialized object can contain code which gets executed. Do not use this option if the serialized object comes from untrusted sources to avoid potential security threats (remote code execution).
