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). It provides an API for sending and receiving data through streams as raw data or strings.
[b]Note:[/b] When exporting to Android, make sure to enable the [code]INTERNET[/code] permission in the Android export preset before exporting the project or using one-click deploy. Otherwise, network communication of any kind will be blocked by Android.

</description>
</method>
<method name="get_available_bytes" qualifiers="const">
<return type="int" />
<description>
Returns the number of bytes this [StreamPeer] has available.
</description>
</method>
<method name="get_data">
<return type="Array" />
<param index="0" name="bytes" type="int" />
<description>
Returns a chunk data with the received bytes. The number of bytes to be received can be requested in the [param bytes] argument. If not enough bytes are available, the function will block until the desired amount is received. This function returns two values, an [enum Error] code and a data array.
</description>
</method>
<method name="get_double">
<return type="float" />
<description>
Gets a double-precision float from the stream.
</description>
</method>
<method name="get_float">
<return type="float" />
<description>
Gets a single-precision float from the stream.
</description>
</method>
<method name="get_partial_data">
<return type="Array" />
<param index="0" name="bytes" type="int" />
<description>
Returns a chunk data with the received bytes. The number 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 [enum Error] code, and a data array.
</description>
</method>
<method name="get_string">
<return type="String" />
<param index="0" name="bytes" type="int" default="-1" />
<description>
Gets an ASCII string with byte-length [param bytes] from the stream. If [param bytes] is negative (default) the length will be read from the stream using the reverse process of [method put_string].
</description>
</method>
<method name="get_u16">
<return type="int" />
<description>
Gets an unsigned 16-bit value from the stream.
</description>

<method name="get_u32">
<return type="int" />
<description>
Gets an unsigned 32-bit value from the stream.
</description>
</method>
<method name="get_u64">
<return type="int" />
<description>
Gets an unsigned 64-bit value from the stream.
</description>
</method>
<method name="get_u8">
<return type="int" />
<description>
Gets an unsigned byte from the stream.
</description>
</method>
<method name="get_utf8_string">
<return type="String" />
<param index="0" name="bytes" type="int" default="-1" />
<description>
Gets an UTF-8 string with byte-length [param bytes] from the stream (this decodes the string sent as UTF-8). If [param bytes] 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" />
<param index="0" name="allow_objects" type="bool" default="false" />
<description>
Gets a Variant from the stream. If [param allow_objects] is [code]true[/code], decoding objects is allowed.
[b]Warning:[/b] Deserialized objects can contain code which gets executed. Do not use this option if the serialized object comes from untrusted sources to avoid potential security threats such as remote code execution.
</description>
</method>
<method name="put_16">
<return type="void" />
<param index="0" name="value" type="int" />
<description>
Puts a signed 16-bit value into the stream.
</description>
</method>
<method name="put_32">
<return type="void" />

<description>
Puts a zero-terminated ASCII string into the stream prepended by a 32-bit unsigned integer representing its size.
[b]Note:[/b] To put an ASCII string without prepending its size, you can use [method put_data]:
[codeblocks]
[gdscript]
put_data("Hello world".to_ascii())
[/gdscript]
[csharp]
PutData("Hello World".ToAscii());
[/csharp]
[/codeblocks]
