Parameters:

value - event data value

appendChars

public void appendChars(char[] buff,
                        int offset,
                        int length)

Append characters to store.

Parameters:

buff - array supplying character data

offset - starting offset in array

length - number of characters

appendString

public int appendString(java.lang.String text)

Append string to store.

Parameters:

text - string to be appended

Returns:

index number of namespace

addQName

public NameImpl addQName(BasicNamespace ns,
                         java.lang.String name)

Create qname, adding it to store.

Parameters:

ns - namespace for name

name - local name

appendNs

public int appendNs(BasicNamespace ns)

Append namespace to store.

Parameters:

ns - namespace to be appended

appendElementStart

public void appendElementStart(BasicNamespace ns,
                               java.lang.String name,
