  • Method Summary

    Modifier and Type
    Method
    Description
    Method
    functionMethod()
    Returns the method that is invoked by JUEL.
    default Method
    functionMethod(String prefix, String localName)
     
    String
    localName()
    The name of the method when used in an expression, like the second part of ${prefix:method()}.
    default Collection<String>
    localNames()
    All the names of the method when used in an expression, like the second part of ${prefix:method()}.
    String
    prefix()
    The prefix of the method when used in an expression, like the first part of ${prefix:method()}.
    default Collection<String>
    prefixes()
    All the prefixes of the method when used in an expression.

  • Method Details

    • 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() throws NoSuchMethodException
      Returns the method that is invoked by JUEL.
      Throws:
      NoSuchMethodException

    • functionMethod

      default Method functionMethod(String prefix, String localName) throws NoSuchMethodException
      Throws:
      NoSuchMethodException
