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.
