RIDs are opaque, which means they do not grant access to the resource by themselves. They are used by the low-level server classes, such as [DisplayServer], [RenderingServer], [TextServer], etc. A low-level resource may correspond to a high-level [Resource], such as [Texture] or [Mesh]. </description> <tutorials> </tutorials> <constructors> <constructor name="RID"> <return type="RID" /> <description> Constructs an empty [RID] with the invalid ID [code]0[/code]. </description> </constructor> <constructor name="RID"> <return type="RID" /> <param index="0" name="from" type="RID" /> <description> Constructs a [RID] as a copy of the given [RID]. </description> </constructor> </constructors> <methods> <method name="get_id" qualifiers="const"> <return type="int" /> <description> Returns the ID of the referenced low-level resource. </description> </method> <method name="is_valid" qualifiers="const"> <return type="bool" /> <description> Returns [code]true[/code] if the [RID] is not [code]0[/code]. </description> </method> </methods> <operators> <operator name="operator !="> <return type="bool" /> <param index="0" name="right" type="RID" /> <description> Returns [code]true[/code] if the [RID]s are not equal. </description> </operator> <operator name="operator <"> <return type="bool" /> <param index="0" name="right" type="RID" /> <description> Returns [code]true[/code] if the [RID]'s ID is less than [param right]'s ID. </description> </operator> <operator name="operator <="> <return type="bool" /> <param index="0" name="right" type="RID" /> <description> Returns [code]true[/code] if the [RID]'s ID is less than or equal to [param right]'s ID. </description> </operator> <operator name="operator =="> <return type="bool" /> <param index="0" name="right" type="RID" /> <description> Returns [code]true[/code] if both [RID]s are equal, which means they both refer to the same low-level resource. </description> </operator> <operator name="operator >"> <return type="bool" /> <param index="0" name="right" type="RID" /> <description> Returns [code]true[/code] if the [RID]'s ID is greater than [param right]'s ID. </description> </operator> <operator name="operator >="> <return type="bool" /> <param index="0" name="right" type="RID" /> <description> Returns [code]true[/code] if the [RID]'s ID is greater than or equal to [param right]'s ID. </description> </operator> </operators> </class>
