Constructor Detail

FElem

public FElem(byte[] n)

Convenience constructor.

Parameters:

n - element name

FElem

public FElem(QNm n)

Constructor.

Parameters:

n - element name

FElem

public FElem(byte[] n,
     Atts nsp)

Convenience constructor.

Parameters:

n - element name

nsp - namespaces

FElem

public FElem(QNm n,
     Atts nsp)

Constructor.

Parameters:

n - element name

nsp - namespaces

FElem

public FElem(QNm nm,
     NodeCache ch,
     NodeCache at,
     Atts nsp)

Constructor.

Parameters:

nm - element name

ch - children; can be null

at - attributes; can be null

nsp - namespaces; can be null

FElem

public FElem(org.w3c.dom.Element elem,
     ANode p,
     TokenMap nss)

Constructor for DOM nodes. Originally provided by Erdal Karaca.

Parameters:

elem - DOM node

p - parent reference

nss - namespaces in scope

Method Detail

optimize

public FElem optimize()

Description copied from class: ANode

Minimizes the memory consumption of the node.

Overrides:

optimize in class ANode

Returns:

self reference

add

public FElem add(ANode node)

Adds a node and updates its parent reference.

Parameters:

node - node to be added

Returns:

self reference

namespaces

public Atts namespaces()

Description copied from class: ANode

Returns all namespaces defined for the nodes. Overwritten by FElem and DBNode.

Overrides:

namespaces in class ANode

Returns:

namespace array

string

public byte[] string()

Description copied from class: ANode

Returns the string value.

Overrides:

string in class FNode

Returns:

string value

baseURI

public byte[] baseURI()

Description copied from class: ANode

Returns the base URI of the node.

Overrides:

baseURI in class ANode

Returns:

base URI

qname

public QNm qname()

Description copied from class: ANode

Returns the QName of the node. This function must only be called for elements, attributes and pi's.

Overrides:

qname in class ANode

Returns:

name

name

public byte[] name()

Description copied from class: ANode

Returns the name of the node, composed of an optional prefix and the local name. This function must only be called for element and attribute nodes. It is more efficient than calling ANode.qname(), as no QNm instance is created.

Overrides:

name in class ANode

Returns:

name

attributes

public AxisMoreIter attributes()

Description copied from class: ANode

Returns an attribute axis iterator.

Overrides:

attributes in class FNode

Returns:

iterator

children

public AxisMoreIter children()

Description copied from class: ANode

Returns a child axis iterator.

Overrides:

children in class FNode

Returns:

iterator

hasChildren

public boolean hasChildren()

Description copied from class: ANode

Returns true if the node has children.

Overrides:

hasChildren in class FNode

Returns:

result of test

copy

public FNode copy()

Description copied from class: ANode

Returns a copy of the node.

Specified by:

copy in class ANode

Returns:

copy

plan

public void plan(FElem plan)

Description copied from class: ExprInfo

Creates an expression tree.

Overrides:

plan in class Item

Parameters:

plan - root element

toString

public java.lang.String toString()

Specified by:

toString in class ExprInfo
