Class ByteArrayUtf8CharSequence

java.lang.Object
org.apache.solr.common.util.ByteArrayUtf8CharSequence
All Implemented Interfaces:
CharSequence, Cloneable, Comparable<Utf8CharSequence>, Utf8CharSequence
public class ByteArrayUtf8CharSequence extends Object implements Utf8CharSequence
A mutable byte[] backed Utf8CharSequence. This is quite similar to the BytesRef of Lucene Do not alter the contents of the byte[] . it may be inconsistent with the cached String This is designed for single-threaded use

  • Field Details

    • buf

      protected byte[] buf

    • offset

      protected int offset

    • hashCode

      protected int hashCode

    • length

      protected int length

    • utf16

      protected volatile String utf16

    • stringProvider

      public Function<ByteArrayUtf8CharSequence,String> stringProvider

  • Constructor Details

    • ByteArrayUtf8CharSequence

      public ByteArrayUtf8CharSequence(String utf16)

    • ByteArrayUtf8CharSequence

      public ByteArrayUtf8CharSequence(byte[] buf, int offset, int length)

  • Method Details

    • getBuf

      public byte[] getBuf()

    • offset

      public int offset()

    • byteAt

      public byte byteAt(int idx)
      Specified by:
      byteAt in interface Utf8CharSequence

    • getStringOrNull

      public String getStringOrNull()
      this is for internal use, to get a cached string value. returns null if there is no cached String value

    • write

      public int write(int start, byte[] buffer, int pos)
      Description copied from interface: Utf8CharSequence
      Write the bytes into a buffer. The objective is to avoid the local bytes being exposed to other classes if the implementation is expected to be immutable. It writes as many bytes as possible into the buffer and then return how many bytes were written. It's the responsibility of the caller to call this method repeatedly and ensure that everything is completely written
      Specified by:
      write in interface Utf8CharSequence
      Parameters:
      start - position from which to start writing
      buffer - the buffer to which to write to
      pos - position to start writing
      Returns:
      no:of bytes written

    • size

      public int size()
      Description copied from interface: Utf8CharSequence
      The size of utf8 bytes
      Specified by:
      size in interface Utf8CharSequence
      Returns:
      the size
