Class AbstractLazyCharSequence

Object

org.thymeleaf.util.AbstractLazyCharSequence

All Implemented Interfaces:

CharSequence, IWritableCharSequence

Direct Known Subclasses:

LazyEscapingCharSequence, LazyProcessingCharSequence

public abstract class AbstractLazyCharSequence
extends Object
implements IWritableCharSequence

Abstract class for character sequences that perform lazy evaluation of their textual contents.

Implementations of this class allow the possibility that their textual contents are actually computed during output writing (if possible), and therefore directly written to output buffers and never requiring being completely resolved in memory.

This is mostly an internal class, and its use is not recommended from user's code.

Children of this class are not thread-safe.

Since:

3.0.0

Method Detail

resolveText

protected abstract String resolveText()

length

public final int length()

Specified by:

length in interface CharSequence

charAt

public final char charAt(int index)

Specified by:

charAt in interface CharSequence

subSequence

public final CharSequence subSequence(int beginIndex,
                                      int endIndex)

Specified by:

subSequence in interface CharSequence

write

public final 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

writeUnresolved

protected abstract void writeUnresolved(Writer writer)
                                 throws IOException

Throws:

IOException

equals

public final boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public final int hashCode()

Overrides:

hashCode in class Object

toString

public final String toString()

Specified by:

toString in interface CharSequence

Overrides:

toString in class Object
