- Method Detail
  - prefix
```
String prefix()
```
    The prefix of the method when used in an expression, like the first part of ${prefix:method()}. Will be used to match the text of the expression to the actual FlowableFunctionDelegate instance.
  - prefixes
```
default Collection<String> prefixes()
```
    All the prefixes of the method when used in an expression. It allows one method to cover multiple prefixes. e.g. ${prefix:method()} or {$code ${alternativePrefix:method()}}. Will be used to match the text of the expression to the actual FlowableFunctionDelegate instance.
  - localName
```
String localName()
```
    The name of the method when used in an expression, like the second part of ${prefix:method()}. Will be used to match the text of the expression to the actual FlowableFunctionDelegate instance.
  - localNames
```
default Collection<String> localNames()
```
    All the names of the method when used in an expression, like the second part of ${prefix:method()}. It allows one method to cover multiple local names. e.g. ${prefix:method()} or ${prefix:alternativeMethod()}. Will be used to match the text of the expression to the actual FlowableFunctionDelegate instance.
  - functionMethod
```
Method functionMethod()
```
    Returns the method that is invoked by JUEL.
