public NativeBuilder(Parser p)

Constructor.

Parameters:

p - parser

Method Detail

init

public void init(java.lang.String db)

Description copied from class: Builder

Initializes the database construction.

Specified by:

init in class Builder

Parameters:

db - name of database

init

public void init(NativeData mdata)

Uses the specified data instance (and its indexes) for the build process.

Parameters:

mdata - data instance

close

public void close()

Description copied from class: Builder

Closes open references.

Specified by:

close in class Builder

addDoc

public void addDoc(byte[] tok)

Description copied from class: Builder

Adds a document node to the database.

Specified by:

addDoc in class Builder

Parameters:

tok - the token to be added (tag name or content)

addElem

public void addElem(int tok,
                    int s,
                    int dis,
                    int a,
                    boolean n)
             throws java.io.IOException

Description copied from class: Builder

Adds an element node to the database. This method stores a preliminary size value; if this node has further descendants, Builder.setSize(int, int) has to be called with the final size value.

Specified by:

addElem in class Builder

Parameters:

tok - the tag name reference

s - the tag namespace

dis - distance (relative parent reference)

a - number of attributes

n - element has namespaces

Throws:

java.io.IOException - I/O exception

addAttr

public void addAttr(int n,
                    int s,
                    byte[] v,
                    int d)

Description copied from class: Builder

Adds an attribute to the database.

Specified by:

addAttr in class Builder

Parameters:

n - attribute name

s - namespace

v - attribute value

d - distance (relative parent reference)

addText

public void addText(byte[] tok,
                    int par,
                    byte kind)

Description copied from class: Builder

Adds a text node to the database.

Specified by:

addText in class Builder

Parameters:

tok - the token to be added (tag name or content)

par - distance (relative parent reference)

kind - the node kind

setSize

Description copied from class: Builder

Stores a size value to the specified table position.

Specified by:

setSize in class Builder

Parameters:

pre - pre reference

val - value to be stored

setAttValue

public void setAttValue(int pre,
