## com.bea.web.tag
Class TextTagSupport

    java.lang.Object
      javax.servlet.jsp.tagext.TagSupport
          com.bea.web.tag.AbstractInputTagSupport
              com.bea.web.tag.TextTagSupport

All Implemented Interfaces:
  IterationTag, Serializable, Tag

public class TextTagSupport
extends AbstractInputTagSupport
implements Serializable

Provides the rendering logic for an HTML form field that accepts text values only. In addition, each instance of this class uses an instance of `com.bea.web.validation.Word` to perform runtime validation of the value for this field. This class places a Word instance in application scope, i.e. accessible via the ServletContext object. The ServletContext is shared by all servlets in a Web application. Consequently, the controller servlet can access the Word to validate user input passed in the HTTP request for this form field.

Constructor Detail

### TextTagSupport

    public TextTagSupport()

  Default constructor, all subclasses of `javax.servlet.jsp.tagext.TagSupport` are required to only define a public constructor with the same signature, and to call the superclass constructor.

Method Detail

### setPattern

    public final void setPattern(String strPattern)

### doStartTag

    public int doStartTag()

  Prints the tag to the JSP writer.

  Specified by:
    `doStartTag` in interface `Tag`
  Returns:
    `javax.servlet.jsp.tagext.Tag.SKIP_BODY` to indicate to the tag handler to skip body evaluation.

### release

    public void release()

  Resets the internal state of this instance. This is called after this tag has rendered itself in the `doStartTag` method. This is needed because the tag handler will reuse this instance for every int tag on the page.

  Specified by:
    `release` in interface `Tag`
  Overrides:
    `release` in class `AbstractInputTagSupport`
