Methods

backspace() → DartBlockValueTreeAlgebraicNode?

Receive a delete (backspace) request, which should delete the right-most component (digit of a constant, variable, operator).

copy() → DartBlockValueTreeAlgebraicNode

Return a deep copy of the node.

override

findNodeByKey(String key) → DartBlockValueTreeAlgebraicNode?

findNodeByKey returns the subtype ValueCompositionNumberNode for ValueCompositionNumberNode and its concrete subclasses.

override

getRightLeaf() → DartBlockValueTreeAlgebraicNode

Used to retrieve current function call value. (See NumberValueComposer)

getRoot() → DartBlockValueTreeAlgebraicNode

Traverse the tree upwards and retrieve the root. The root is defined as the node which has no parent.

override

getValue(DartBlockArbiter arbiter) → num

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

receiveDigit(num digit) → DartBlockValueTreeAlgebraicNode

Receive a digit 0-9.

receiveDot() → DartBlockValueTreeAlgebraicNode

Receive a dot, indicating the user wants to compose a decimal constant value.

receiveDynamicValue(DartBlockDynamicValue dynamicValue) → DartBlockValueTreeAlgebraicNode

Receive a dynamic value, which may be a variable or a function call.

receiveNegation() → DartBlockValueTreeAlgebraicNode

receiveOperator(DartBlockAlgebraicOperator operator) → DartBlockValueTreeAlgebraicNode

Receive an operator (+, -, *, /)

replaceChild(DartBlockValueTreeAlgebraicNode oldChild, DartBlockValueTreeAlgebraicNode? newChild) → DartBlockValueTreeAlgebraicNode?

Only implemented by ArithmeticOperatorNode which features two child (left, right) properties. All other subclasses have empty implementations.

toJson() → Map<String, dynamic>

override

toScript({DartBlockTypedLanguage language = DartBlockTypedLanguage.java}) → String

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
