Detailed Description

There are three types of nodes:

Tree nodes, which have a name and contain other nodes as children
Array nodes, which also contain other nodes but aren't considered part of a tree
Leaf nodes, which contain the actual data

This interface provides access to the tree structure and to the contents of array nodes, but it does not provide access to the internal structure of leaf nodes. Access to leaf data is provided via two means:

PPFrame::expand(), which provides expanded text
The PPNode::split*() functions, which provide metadata about certain types of tree node

Member Function Documentation

PPNode::getChildren ( )

Get an array-type node containing the children of this node.

Returns false if this is not a tree node.

Returns: PPNode

Implemented in PPNode_Hash_Attr, PPNode_Hash_Array, PPNode_Hash_Text, PPNode_DOM, and PPNode_Hash_Tree.

PPNode::getChildrenOfType ( $type )

Get all children of this tree node which have a given name.

Returns an array-type node, or false if this is not a tree node.

Parameters

string $type

Returns: bool|PPNode

Implemented in PPNode_Hash_Attr, PPNode_Hash_Array, PPNode_Hash_Text, PPNode_DOM, and PPNode_Hash_Tree.

PPNode::getFirstChild ( )

Get the first child of a tree node.

False if there isn't one.

Returns: PPNode

Implemented in PPNode_Hash_Attr, PPNode_Hash_Array, PPNode_Hash_Text, PPNode_DOM, and PPNode_Hash_Tree.

PPNode::getLength ( )

Returns the length of the array, or false if this is not an array-type node.

Implemented in PPNode_Hash_Attr, PPNode_Hash_Array, PPNode_Hash_Text, PPNode_DOM, and PPNode_Hash_Tree.

PPNode::getName ( )

Get the name of this node.

The following names are defined here:

h A heading node. template A double-brace node. tplarg A triple-brace node. title The first argument to a template or tplarg node. part Subsequent arguments to a template or tplarg node. #nodelist An array-type node

The subclass may define various other names for tree and leaf nodes.
