Modifier and Type	Method	Description
(package private) abstract boolean	equalsRange(ByteString other, int offset, int length)	Check equality of the substring of given length of this object starting at zero with another ByteString substring starting at offset.
protected int	getTreeDepth()	Return the depth of the tree representing this ByteString, if any, whose root is this node.
protected boolean	isBalanced()	Return true if this ByteString is literal (a leaf node) or a flat-enough tree in the sense of RopeByteString.
(package private) void	writeToReverse(ByteOutput byteOutput)	This method behaves exactly the same as ByteString.writeTo(ByteOutput) unless the ByteString is a rope.

Method Detail

getTreeDepth

protected final int getTreeDepth()

Description copied from class: ByteString

Return the depth of the tree representing this ByteString, if any, whose root is this node. If this is a leaf node, return 0.

Specified by:

getTreeDepth in class ByteString

Returns:

tree depth or zero

isBalanced

protected final boolean isBalanced()

Description copied from class: ByteString

Return true if this ByteString is literal (a leaf node) or a flat-enough tree in the sense of RopeByteString.

Specified by:

isBalanced in class ByteString

Returns:

true if the tree is flat enough

writeToReverse

void writeToReverse(ByteOutput byteOutput)
             throws java.io.IOException

Description copied from class: ByteString

This method behaves exactly the same as ByteString.writeTo(ByteOutput) unless the ByteString is a rope. For ropes, the leaf nodes are written in reverse order to the byteOutput.

Specified by:

writeToReverse in class ByteString

Parameters:

byteOutput - the output target to receive the bytes

Throws:

java.io.IOException - if an I/O error occurs

See Also:

UnsafeByteOperations#unsafeWriteToReverse(ByteString, ByteOutput)

equalsRange

abstract boolean equalsRange(ByteString other,
                             int offset,
                             int length)

Check equality of the substring of given length of this object starting at zero with another ByteString substring starting at offset.

Parameters:

other - what to compare a substring in

offset - offset into other

length - number of bytes to compare

Returns:

true for equality of substrings, else false.
