[#absl-CordBuffer-SetLength]
= xref:absl.adoc[absl]::xref:absl/CordBuffer.adoc[CordBuffer]::SetLength
:relfileprefix: ../../
:mrdocs:

Sets the data length of this instance. Applications must make sure all data of the specified length has been initialized before adding a CordBuffer to a Cord: failure to do so will lead to undefined behavior. Setting the length to a small value or zero does not release any memory held by this CordBuffer instance. Requires `length <= capacity()`. Applications should preferably use the `IncreaseLengthBy()` method above in combination with the 'available()` or `available_up_to()` methods.
