<argument index="0" name="divisor" type="String">
</argument>
<argument index="1" name="allow_empty" type="bool" default="True">
</argument>
<argument index="2" name="maxsplit" type="int" default="0">
</argument>
<description>
Splits the string by a divisor string and returns an array of the substrings.
[b]Example:[/b] [code]"One,Two,Three"[/code] will return [code]["One","Two","Three"][/code] if split by [code]","[/code].
If [code]maxsplit[/code] is given, at most maxsplit number of splits occur, and the remainder of the string is returned as the final element of the list (thus, the list will have at most maxsplit+1 elements)

</method>
<method name="to_ascii">
<return type="PoolByteArray">
</return>
<description>
Converts the String (which is a character array) to [PoolByteArray] (which is an array of bytes). The conversion is sped up in comparison to [method to_utf8] with the assumption that all the characters the String contains are only ASCII characters.

</method>
<method name="to_float">
<return type="float">
</return>
<description>
2017-10-22 20:55:21 +00:00
Converts a string containing a decimal number into a [code]float[/code].
</description>
</method>
<method name="to_int">
<return type="int">
</return>
<description>
2017-10-22 20:55:21 +00:00
Converts a string containing an integer number into an [code]int[/code].
</description>
</method>
<method name="to_lower">
<return type="String">
</return>
<description>
2017-10-22 20:55:21 +00:00
Returns the string converted to lowercase.
</description>
</method>
<method name="to_upper">
<return type="String">
</return>
<description>
2017-10-22 20:55:21 +00:00
Returns the string converted to uppercase.
</description>
</method>
<method name="to_utf8">
<return type="PoolByteArray">
</return>
<description>
Converts the String (which is an array of characters) to [PoolByteArray] (which is an array of bytes). The conversion is a bit slower than [method to_ascii], but supports all UTF-8 characters. Therefore, you should prefer this function over [method to_ascii].

<method name="trim_prefix">
<return type="String">
</return>
<argument index="0" name="prefix" type="String">
</argument>
<description>
Removes a given string from the start if it starts with it or leaves the string unchanged.

</method>
<method name="trim_suffix">
<return type="String">
</return>
<argument index="0" name="suffix" type="String">
</argument>
<description>
Removes a given string from the end if it ends with it or leaves the string unchanged.

</method>
<method name="xml_escape">
<return type="String">
</return>
<description>
2017-10-22 20:55:21 +00:00
Returns a copy of the string with special characters escaped using the XML standard.
