Interface FlowableShortHandExpressionFunction

All Superinterfaces:

FlowableExpressionEnhancer, FlowableFunctionDelegate

All Known Implementing Classes:

AbstractFlowableShortHandExpressionFunction, AbstractFlowableVariableExpressionFunction, AbstractVariableComparatorExpressionFunction, VariableContainsAnyExpressionFunction, VariableContainsExpressionFunction, VariableEqualsExpressionFunction, VariableExistsExpressionFunction, VariableGetExpressionFunction, VariableGetOrDefaultExpressionFunction, VariableGreaterThanExpressionFunction, VariableGreaterThanOrEqualsExpressionFunction, VariableIsEmptyExpressionFunction, VariableIsNotEmptyExpressionFunction, VariableLowerThanExpressionFunction, VariableLowerThanOrEqualsExpressionFunction, VariableNotEqualsExpressionFunction

public interface FlowableShortHandExpressionFunction
extends FlowableFunctionDelegate, FlowableExpressionEnhancer

Implementations of this interface are both - a FlowableFunctionDelegate, allowing to define a custom function to be used in an Expression - a FlowableExpressionEnhancer, allowing to use a shorthand version of a function that gets expanded by enhancing the expression string before it gets transformed to an Expression instance. This simplifies registration with an engine configuration, as only one instance needs to be added instead of keeping both in sync.
