Interfaces

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

Properties

$children  : array<string, ChildNodeInterface>
$name  : string

Methods

__serialize()  : array<string|int, mixed>
When storing to cache, we only store FE relevant properties and skip various BE related properties which then default to class defaults when unserialized. This is done to create smaller php cache files.
addChild()  : void
Helper methods to operate on children.
addComment()  : void
Helper methods to attach TypoScript tokens to a node.
appendValue()  : void
getChildByName()  : ChildNodeInterface|null
getComments()  : array<string|int, TokenStreamInterface>
getIdentifier()  : string
getNextChild()  : iterable<string|int, ChildNodeInterface>
getOriginalValueTokenStream()  : TokenStreamInterface|null
getPreviousValue()  : string|null
getValue()  : string|null
hasChildren()  : bool
isValueNull()  : bool
removeChildByName()  : void
Note this does *not* choke if that child does not exist, so we can "blindly" remove without error.
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
updateName()  : void
This forces $this->name NOT to be readonly.
serialize()  : array<string|int, mixed>

Properties

Methods

__serialize()

When storing to cache, we only store FE relevant properties and skip various BE related properties which then default to class defaults when unserialized. This is done to create smaller php cache files.

public final __serialize() : array<string|int, mixed>
Return values
array<string|int, mixed>

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

getIdentifier()

public getIdentifier() : string
Return values
string

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()

Note this does *not* choke if that child does not exist, so we can "blindly" remove without error.

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

updateName()

This forces $this->name NOT to be readonly.

public updateName(string $name) : void

Used with '<' operator on tree root to copy: foo = value bar < foo The 'foo' object node is copied, but added to AST as name 'bar'

Parameters
$name : string

serialize()

protected serialize() : array<string|int, mixed>
Return values
array<string|int, mixed>
