Package org.elasticsearch.common.bytes

Class CompositeBytesReference

java.lang.Object
org.elasticsearch.common.bytes.AbstractBytesReference
org.elasticsearch.common.bytes.CompositeBytesReference
All Implemented Interfaces:
Comparable<BytesReference>, BytesReference, org.elasticsearch.common.xcontent.ToXContent, org.elasticsearch.common.xcontent.ToXContentFragment
public final class CompositeBytesReference extends AbstractBytesReference
A composite BytesReference that allows joining multiple bytes references into one without copying. Note, toBytesRef() will materialize all pages in this BytesReference.

    • get

      public byte get​(int index)
      Description copied from interface: BytesReference
      Returns the byte at the specified index. Need to be between 0 and length.

    • indexOf

      public int indexOf​(byte marker, int from)
      Description copied from interface: BytesReference
      Finds the index of the first occurrence of the given marker between within the given bounds.

      indexOf in interface BytesReference
      Overrides:
      indexOf in class AbstractBytesReference
      Parameters:
      marker - marker byte to search
      from - lower bound for the index to check (inclusive)
      Returns:
      first index of the marker or -1 if not found

    • length

      public int length()
