:relfileprefix: ../../../
:mrdocs:

Bitwise OR a bit range from `srcArray` into this array.

== Synopsis

Declared in `<bdlc_bitarray.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
void
orEqual(
    std::size_t dstIndex,
    xref:BloombergLP/bdlc/BitArray.adoc[BitArray] const& srcArray,
    std::size_t srcIndex,
    std::size_t numBits);
----

== Description

Bitwise OR the specified `numBits` in this array, beginning at the specified `dstIndex`, with values from the specified `srcArray` beginning at the specified `srcIndex` (retaining the results). The behavior is undefined unless `dstIndex + numBits <= length()` and `srcIndex + numBits <= srcArray.length()`.

== Parameters

[cols="1,4"]
