ChildNodeInterface extends NodeInterface

The created AST consists of a NodeRoot object with nested NodeObject children.

This is the interface implemented by all children nodes (not RootNode).

Methods

addChild()  : void
Helper methods to operate on children.
addComment()  : void
Helper methods to attach TypoScript tokens to a node.
appendValue()  : void
flatten()  : array<string|int, mixed>
Flatten the tree. A RootNode with a ChildNode "foo" and value "fooValue", with this ChildNode again having a ChildNode "bar" and value "barValue" becomes: [ 'foo' => 'fooValue', 'foo.bar' => 'barValue', ]
getChildByName()  : ChildNodeInterface|null
getComments()  : array<string|int, TokenStreamInterface>
getIdentifier()  : string
getName()  : string|null
Helper methods for node name.
getNextChild()  : iterable<string|int, ChildNodeInterface>
getOriginalValueTokenStream()  : TokenStreamInterface|null
getPreviousValue()  : string|null
getValue()  : string|null
hasChildren()  : bool
isValueNull()  : bool
removeChildByName()  : void
setIdentifier()  : void
An identifier for this node. Typically, a hash of some kind. This identifier is unique within the tree, by being created from the parent identifier plus the name. This identifier is used in the backend, when referencing single nodes.
setOriginalValueTokenStream()  : void
Helper method for backend object browser to retrieve the original stream when a constant substitution happened, only set by CommentAwareAstBuilder.
setPreviousValue()  : void
Previous value is only set by comment aware ast builder. It is used in constant editor to see if a value has been changed.
setValue()  : void
Helper methods for value.
sortChildren()  : void
toArray()  : array<string|int, mixed>|null
b/w compat method to turn AST into an array.
updateName()  : void

Methods

addComment()

Helper methods to attach TypoScript tokens to a node.

public addComment(TokenStreamInterface $tokenStream) : void

This is used in ext:tstemplate "Constant Editor" and "Object Browser" and handled by CommentAwareAstBuilder.

Parameters
$tokenStream : TokenStreamInterface

appendValue()

public appendValue(string $value) : void
Parameters
$value : string

flatten()

Flatten the tree. A RootNode with a ChildNode "foo" and value "fooValue", with this ChildNode again having a ChildNode "bar" and value "barValue" becomes: [ 'foo' => 'fooValue', 'foo.bar' => 'barValue', ]

public flatten([string $prefix = '' ]) : array<string|int, mixed>

Flattening a TypoScript tree is especially used for constants to quickly look up constants when parsing setup node value streams that use T_CONSTANT tokens.

Parameters
$prefix : string = ''
Return values
array<string|int, mixed>

getIdentifier()

public getIdentifier() : string
Return values
string

getName()

Helper methods for node name.

public getName() : string|null
Return values
string|null

getPreviousValue()

public getPreviousValue() : string|null
Return values
string|null

getValue()

public getValue() : string|null
Return values
string|null

hasChildren()

public hasChildren() : bool
Return values
bool

isValueNull()

public isValueNull() : bool
Return values
bool

removeChildByName()

public removeChildByName(string $name) : void
Parameters
$name : string

setIdentifier()

An identifier for this node. Typically, a hash of some kind. This identifier is unique within the tree, by being created from the parent identifier plus the name. This identifier is used in the backend, when referencing single nodes.

public setIdentifier(string $identifier) : void

Calculating identifiers is initiated by calling setIdentifier() on RootNode, which will recurse the tree. Call this on the final tree, after AST calculation finished, so AST building itself does not need to fiddle with identifier updates when for instance tree parts are cloned using '<' operator. Note this value is skipped when persisting to caches since it's a Backend related thing that does not use cached context: When retrieving nodes from cache (e.g. in Frontend), the identifier is null and calling the getter will throw an exception.

Parameters
$identifier : string

setOriginalValueTokenStream()

Helper method for backend object browser to retrieve the original stream when a constant substitution happened, only set by CommentAwareAstBuilder.

public setOriginalValueTokenStream(TokenStreamInterface|null $tokenStream) : void
Parameters
$tokenStream : TokenStreamInterface|null

setPreviousValue()

Previous value is only set by comment aware ast builder. It is used in constant editor to see if a value has been changed.

public setPreviousValue(string|null $value) : void
Parameters
$value : string|null

setValue()

Helper methods for value.

public setValue(string|null $value) : void
Parameters
$value : string|null

sortChildren()

public sortChildren() : void

toArray()

b/w compat method to turn AST into an array.

public toArray() : array<string|int, mixed>|null

Note we're NOT using magic __toArray() here to avoid calling array-cast of AST by accident: toArray() should be called explicitly if needed, which makes it much easier to drop this b/w compat method when we later want to drop that layer.

Note RootNode always returns an array, while ObjectNode's may return null.

Return values
array<string|int, mixed>|null

updateName()

public updateName(string $name) : void
Parameters
$name : string
