PropertyValueDelegate class

A delegate class that helps retrieving the value of a node property from multiple sources such as conditions, variables, data, and node values.

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

Static Methods

getPredefinedVariableValue<R extends Object>(String path, {required ScopedValues scopedValues, required Object? nodeValue}) → R?

Retrieves the value of a predefined variable name using given path. Predefined variables are data, index, and item.

getPropertyValue<R extends Object>(BaseNode node, String property, {required ScopedValues scopedValues}) → R?

Retrieves the value of a node property from multiple sources. Sources: Conditions, Variables, Data, item, index, and Node Values.

getPropertyValueFromCondition<R extends Object>(BaseNode node, String property, {required ScopedValues scopedValues}) → R?

Retrieves the value of a node property from a condition by evaluating the condition if it exists.

getPropertyValueFromNodeValues<R extends Object>(BaseNode node, String property, {required ScopedValues scopedValues}) → R?

Retrieves the value of a node property from node values by evaluating the node values if it exists.

getPropertyValueFromVariable<R extends Object>(BaseNode node, String property, {required ScopedValues scopedValues}) → R?

Retrieves the value of a node property from a variable by evaluating the variable path if it exists. This also supports predefined variables such as data, index, and item.

getVariableProperties(Object? value, VariableType type) → Map<String, dynamic>

Creates a map of variable properties for given value and type. This is experimental and is subject to change. It is used for development purposes only.

getVariableValueFromPath<R extends Object>(String path, {required ScopedValues scopedValues}) → R?

Retrieves the value of a variable path. This also supports predefined variables such as data, index, and item.

putValueInJsonPath(String path, Object? value, Map<String, dynamic> data) → void

retrievePredefinedVariableValue(VariableMatch match, ScopedValues scopedValues) → Object?

substituteJsonPath(String text, Map<String, dynamic> data) → (Object?, JsonPointer?)

Substitutes json paths found in text with values from data. supported text format:

substituteVariables(String text, {required ScopedValues scopedValues, required NullSubstitutionMode nullSubstitutionMode}) → String

Substitutes variables & data paths used in given text with their values.
