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

getChildren()

PPNode::getChildren

(

)

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

Returns false if this is not a tree node.

Returns

false|PPNode

Implemented in PPNode_Hash_Array, PPNode_Hash_Attr, PPNode_Hash_Text, and PPNode_Hash_Tree.

getChildrenOfType()

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

false|PPNode

Implemented in PPNode_Hash_Array, PPNode_Hash_Attr, PPNode_Hash_Text, and PPNode_Hash_Tree.

getFirstChild()

PPNode::getFirstChild

(

)

False if there isn't one.

Returns

false|PPNode

Implemented in PPNode_Hash_Array, PPNode_Hash_Attr, PPNode_Hash_Text, and PPNode_Hash_Tree.

getLength()

PPNode::getLength

Implemented in PPNode_Hash_Array, PPNode_Hash_Attr, PPNode_Hash_Text, and PPNode_Hash_Tree.

getName()

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.

Returns

string

Implemented in PPNode_Hash_Array, PPNode_Hash_Attr, PPNode_Hash_Text, and PPNode_Hash_Tree.

getNextSibling()

PPNode::getNextSibling

(

)

Get the next sibling of any node.

False if there isn't one

Returns

false|PPNode

Implemented in PPNode_Hash_Array, PPNode_Hash_Attr, PPNode_Hash_Text, and PPNode_Hash_Tree.

item()

PPNode::item

(

$i

)

Returns an item of an array-type node.

Parameters

int

$i

Returns

bool|PPNode

Implemented in PPNode_Hash_Array, PPNode_Hash_Attr, PPNode_Hash_Text, and PPNode_Hash_Tree.

splitArg()

PPNode::splitArg

(

)

Split a "<part>" node into an associative array containing: name PPNode name index String index value PPNode value.

Returns

array

Implemented in PPNode_Hash_Array, PPNode_Hash_Attr, PPNode_Hash_Text, and PPNode_Hash_Tree.

splitExt()

PPNode::splitExt
