Functions

fun CompositionNode.filter(filter: (CompositionNode) -> Boolean): CompositionNode?

Filters a CompositionNode and its hierarchy based on the provided filter function. The method recursively applies the filter to the node and its children, creating a new hierarchy that contains only the nodes for which the filter returns true. If the filter condition fails for the root node, null is returned.

fun CompositionNode.find(predicate: (CompositionNode) -> Boolean): CompositionNode?

Finds first CompositionNode to match the given predicate.

fun CompositionNode.findAll(filter: (CompositionNode) -> Boolean): List<CompositionNode>

Finds all CompositionNode instances in the current node hierarchy that satisfy the given filter. Traverses the hierarchy recursively, evaluating each node and its children.

fun CompositionNode.findGroups(): List<GroupNode>

find all descendant GroupNode nodes, including potentially this node

fun CompositionNode.findImages(): List<ImageNode>

find all descendant ImageNode nodes, including potentially this node

fun CompositionNode.findShapes(): List<ShapeNode>

find all descendant ShapeNode nodes, including potentially this node

fun CompositionNode.findTerminals(filter: (CompositionNode) -> Boolean): List<CompositionNode>

Recursively finds all terminal nodes within the composition tree starting from the current node and applies the provided filter to determine which nodes to include in the result.

fun CompositionNode.map(mapper: (CompositionNode) -> CompositionNode): CompositionNode

fun CompositionNode.remove()

remove node from its parent CompositionNode

fun CompositionNode.visitAll(visitor: CompositionNode.() -> Unit)

visit this CompositionNode and all descendant nodes and execute visitor
