Interface Chunking

All Known Implementing Classes:

ChunkingImpl

public interface Chunking

The Chunking interface specifies a set of chunks over a shared underlying character sequence. Each chunk in the chunk set should provide a valid slice of that character sequence.

A simple mutable implementation of the Chunking interface is provided by the ChunkingImpl class.

Method Summary

CharSequence	charSequence() Returns the character sequence underlying this chunking.
Set<Chunk>	chunkSet() Returns the chunks for this chunking.
boolean	equals(Object that) Returns true if the specified object is a chunking equal to this one.
int	hashCode() Returns the hash code for this chunking.

Method Detail

chunkSet

Set<Chunk> chunkSet()

Returns the chunks for this chunking.

Returns:

The chunks for this chunking.

charSequence

CharSequence charSequence()

Returns the character sequence underlying this chunking.

Returns:

The character sequence underlying this set of chunks.

equals

boolean equals(Object that)

Returns true if the specified object is a chunking equal to this one. Equality for chunking is defined by character sequence yield equality and chunk set equality. Character sequences are tested for equality with Strings.equalCharSequence(CharSequence,CharSequence) and chunks are compared as sets with elements tested for equality using Chunk.equals(Object). There is a utility implementation of this definition provided for chunkings in ChunkingImpl.equal(Chunking,Chunking).

Overrides:

equals in class Object

Parameters:

that - Object to compare.

Returns:

true if the specified object is a chunking equal to this one.

hashCode

int hashCode()

Returns the hash code for this chunking. Hash codes for chunkings are defined by:

 hashCode() 
   = Strings.hashCode(charSequence())
     + 31 * chunkSet().hashCode()
 

There is a utility implementation of this definition provided for chunkings in ChunkingImpl.hashCode(Chunking).

Overrides:

hashCode in class Object

Returns:

The hash code for this chunking.
