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.

Gets a signed 16-bit value from the stream.
</description>
</method>
<method name="get_32">
<return type="int" />
<description>
Gets a signed 32-bit value from the stream.
</description>

<description>
Gets a signed byte from the stream.
</description>
</method>
<method name="get_available_bytes" qualifiers="const">
<return type="int" />
<description>
Returns the amount of bytes this [StreamPeer] has available.
</description>
</method>
<method name="get_data">
<return type="Array" />
<argument index="0" name="bytes" type="int" />
<description>
Returns a chunk data with the received bytes. The amount of bytes to be received can be requested in the [code]bytes[/code] argument. If not enough bytes are available, the function will block until the desired amount is received. This function returns two values, an [enum @GlobalScope.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" />
<argument index="0" name="bytes" type="int" />
<description>
Returns 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 [enum @GlobalScope.Error] code, and a data array.
</description>
</method>
<method name="get_string">
<return type="String" />
<argument index="0" name="bytes" type="int" default="-1" />
<description>
Gets 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>
</method>
<method name="get_u16">
<return type="int" />
<description>
Gets an unsigned 16-bit value from the stream.
</description>
</method>
<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" />
<argument index="0" name="bytes" type="int" default="-1" />
<description>
Gets an UTF-8 string with byte-length [code]bytes[/code] from the stream (this decodes the string sent as UTF-8). 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" />
<argument index="0" name="allow_objects" type="bool" default="false" />
<description>
Gets a Variant from the stream. If [code]allow_objects[/code] 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" />
<argument 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" />

[codeblocks]
[gdscript]
put_data("Hello world".to_ascii())
[/gdscript]
[csharp]
PutData("Hello World".ToAscii());
[/csharp]
[/codeblocks]
