Method Detail

setName

public void setName(String n)
             throws JspTagException

Throws:

JspTagException

setNotfound

public void setNotfound(String i)
                 throws JspTagException

Throws:

JspTagException

getNodeVar

public Node getNodeVar()
                throws JspTagException

A fieldprovider also provides a node.

Specified by:

getNodeVar in interface FieldProvider

Throws:

JspTagException

getFieldVar

public Field getFieldVar()

Specified by:

getFieldVar in interface FieldProvider

Returns:

the field contained in the tag

setFieldVar

protected void setFieldVar(String n)
                    throws JspTagException

Throws:

JspTagException

setFieldVar

protected void setFieldVar()
                    throws JspTagException

Throws:

JspTagException

convert

protected String convert(String s)
                  throws JspTagException

Does something with the generated output. This default implementation does nothing, but extending classes could override this function.

Throws:

JspTagException

handleEditTag

protected void handleEditTag()

Method to handle the EditTag if it is present around fields and their nodes.

When the FieldTag finds itself inside an EditTag then it will register its contents with the EditTag. The EditTag can provide access to an editor. Not only the field and its nodes will be registered but also the query it originated from. It passes these to the method EditTag#registerField(Query query, int nodenr, String fieldName).

Since:

MMBase-1.8
