Class AbstractLazyCharSequence

  • All Implemented Interfaces:
    java.lang.CharSequence, IWritableCharSequence
    Direct Known Subclasses:
    LazyEscapingCharSequence, LazyProcessingCharSequence
    public abstract class AbstractLazyCharSequence
extends java.lang.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

        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:
        java.io.IOException - if an input/output exception happens during writing
