E4HtmlElement_Intf

public class E4HtmlContent
extends E4HtmlElementGeneral
implements E4HtmlElement_Intf

Base content of HTML elements, not defined or structured in HTML tags, just pure text. Some elements may contain other tags, mixed with text. E.g. a >TABLE< tag may only contain tags, no text. But a <TD> tag may contain both.

Constructor Detail

E4HtmlContent

public E4HtmlContent()

Method Detail

append

public void append(java.lang.String s)

Append a String. Appends a String to the internal StringBuffer object which collects all the content temporary unless the E4ServletImplementation_Intf.write(E4HtmlElement) function is called with toHtml(e4s.util.E4StringBufferHtml, e4s.servlet.E4ServletImplementation_Intf) as parameter.

Parameters:

s - the string to append

addElement

public void addElement(E4HtmlElement_Intf dummy)
                throws java.lang.Throwable

-- do not call this function, an error will result --. This function is for compatibility reasons only, but it should never be called. The reason is, that this object cannot have any subnodes.

Parameters:

dummy - will be ignored and result in an error anyway

Throws:

java.lang.Throwable

toHtml

public void toHtml(E4StringBufferHtml buf,
                   E4ServletImplementation_Intf servlet)

Content of the object as HTML output. The internal StringBuffer is returned (see {link append(String s)}). This function is used by the other recursive toHtml() calls when the element vector is completley collected to build the HTML content.

Specified by:

toHtml in interface E4HtmlElement_Intf

Overrides:

toHtml in class E4HtmlElementGeneral

servlet - the servlet environment currently running in

toHtml_Hidden

public void toHtml_Hidden(E4StringBufferHtml buf,
                          E4ServletImplementation_Intf servlet)

getStringContent

public java.lang.String getStringContent()

Description copied from interface: E4HtmlElement_Intf

Get the pure string content of the elements and sub elements, without any tag information.

Specified by:

getStringContent in interface E4HtmlElement_Intf

Overrides:

getStringContent in class E4HtmlElementGeneral

Returns:

the pure string content or null if none

removeAll

public void removeAll()

Destroys the StringBuffer

Specified by:

removeAll in interface E4HtmlElement_Intf

Overrides:

removeAll in class E4HtmlElementGeneral

debugToString

public java.lang.String debugToString(int n)

Output for debugging reasons. General: returns a tree-like formatted display of the elements vector including recursivley all sub elements. This special case: has no subnodes (elements), the String "+--content" followed by the length of the internal StringBuffer content is returned

Specified by:

debugToString in interface E4HtmlElement_Intf

Overrides:

debugToString in class E4HtmlElementGeneral

Parameters:

n - the level (start with 0 when called external)

Returns:

the structured String with at the end of each line

isContentClass

public boolean isContentClass()

Returns true. This function returns false normally, except for this, the collecting class, E4HtmlContent which is a special case. It is detected, if it is the end of the elements. If not, such a class is added, othervise only a string is appended. This avoids excessive creation of objects.

Specified by:

isContentClass in interface E4HtmlElement_Intf

Overrides:

isContentClass in class E4HtmlElementGeneral

Returns:

always true

_getSVNVersionString

public static java.lang.String _getSVNVersionString()
