Field Detail

isBackingBytesReused

protected boolean isBackingBytesReused

EMPTY

public static final Binary EMPTY

Method Detail

toStringUsingUTF8

public abstract String toStringUsingUTF8()

length

public abstract int length()

writeTo

public abstract void writeTo(OutputStream out)
                      throws IOException

Throws:

IOException

writeTo

public abstract void writeTo(DataOutput out)
                      throws IOException

Throws:

IOException

getBytes

public abstract byte[] getBytes()

getBytesUnsafe

public abstract byte[] getBytesUnsafe()

Variant of getBytes() that avoids copying backing data structure by returning backing byte[] of the Binary. Do not modify backing byte[] unless you know what you are doing.

Returns:

backing byte[] of correct size, with an offset of 0, if possible, else returns result of getBytes()

slice

public abstract Binary slice(int start,
           int length)

compareTo

public abstract int compareTo(Binary other)

Specified by:

compareTo in interface Comparable<Binary>

toByteBuffer

public abstract ByteBuffer toByteBuffer()

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object

copy

public Binary copy()

isBackingBytesReused

public boolean isBackingBytesReused()

Signals if backing bytes are owned, and can be modified, by producer of the Binary

Returns:

if backing bytes are held on by producer of the Binary
