Class AggregateCharSequence

Object

org.thymeleaf.util.AggregateCharSequence

All Implemented Interfaces:

Serializable, CharSequence, IWritableCharSequence

public final class AggregateCharSequence
extends Object
implements Serializable, IWritableCharSequence

Character sequence that aggregates one or several CharSequence objects, without the need to clone them or convert them to String.

Special implementation of the CharSequence interface that can replace String objects wherever a specific text literal is composed of several parts and we want to avoid creating new String objects for them, using instead objects of this class that simply keep an array of references to the original CharSequences.

Note that any mutable CharSequence implementations used to build objects of this class should never be modified after the creation of the aggregated object.

This class is thread-safe

Method Detail

length

public int length()

Specified by:

length in interface CharSequence

charAt

public char charAt(int index)

Specified by:

charAt in interface CharSequence

subSequence

public CharSequence subSequence(int beginIndex,
                                int endIndex)

Specified by:

subSequence in interface CharSequence

write

public void write(Writer writer)
           throws IOException

Description copied from interface: IWritableCharSequence

Write the contents of this char sequence directly to an output Writer.

This method can avoid the need to create a String object containing all the contents in this character sequence just when we want to write it to a Writer.

Specified by:

write in interface IWritableCharSequence

Parameters:

writer - the writer to write the character sequence to.

Throws:

IOException - if an input/output exception happens during writing

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

contentEquals

public boolean contentEquals(StringBuffer sb)

contentEquals

public boolean contentEquals(CharSequence cs)

toString

public String toString()

Specified by:

toString in interface CharSequence

Overrides:

toString in class Object
