Package org.apache.taglibs.standard.tag.common.core

Class OutSupport

  • All Implemented Interfaces:
    jakarta.servlet.jsp.tagext.BodyTag, jakarta.servlet.jsp.tagext.IterationTag, jakarta.servlet.jsp.tagext.JspTag, jakarta.servlet.jsp.tagext.Tag, Serializable
    Direct Known Subclasses:
    OutTag, OutTag
    public class OutSupport
extends jakarta.servlet.jsp.tagext.BodyTagSupport

    Support for handlers of the <out> tag, which simply evalutes and prints the result of the expression it's passed. If the result is null, we print the value of the 'default' attribute's expression or our body (which two are mutually exclusive, although this constraint is enforced outside this handler, in our TagLibraryValidator).
