## com.bea.web.tag
Class DoubleTagSupport

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

All Implemented Interfaces:
  IterationTag, Serializable, Tag

public class DoubleTagSupport
extends AbstractInputTagSupport
implements Serializable

Provides the rendering logic for an HTML form field that accepts float values only. In addition, each instance of this class uses an instance of `com.bea.web.validation.DoubleWord` to perform runtime validation of the value for this field. This class places an DoubleWord 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 DoubleWord to validate user input passed in the HTTP request for this form field.

Constructor Detail

### DoubleTagSupport

    public DoubleTagSupport()

  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

### getMinInclusive

    public final String getMinInclusive()

### getMaxInclusive

    public final String getMaxInclusive()

### getMinExclusive

    public final String getMinExclusive()

### getMaxExclusive

    public final String getMaxExclusive()

### setMinInclusive

    public final void setMinInclusive(String str)

### setMaxInclusive

    public final void setMaxInclusive(String str)

### setMinExclusive

    public final void setMinExclusive(String str)

### setMaxExclusive

    public final void setMaxExclusive(String str)

### 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`
