## Class BshMethod

- java.lang.Object
- - org.gjt.sp.jedit.bsh.BshMethod

- All Implemented Interfaces:
    java.io.Serializable
  Direct Known Subclasses:
    DelayedEvalBshMethod

      public class BshMethod
      extends java.lang.Object
      implements java.io.Serializable

  This represents an instance of a bsh method declaration in a particular namespace. This is a thin wrapper around the BSHMethodDeclaration with a pointer to the declaring namespace.

  When a method is located in a subordinate namespace or invoked from an arbitrary namespace it must nontheless execute with its 'super' as the context in which it was declared.

- - ### Method Detail

    - #### getParameterTypes

          public java.lang.Class[] getParameterTypes()

      Get the argument types of this method. loosely typed (untyped) arguments will be represented by null argument types.

    - #### getParameterNames

          public java.lang.String[] getParameterNames()

    - #### getReturnType

          public java.lang.Class getReturnType()

      Get the return type of the method.
      Returns:
        Returns null for a loosely typed return value, Void.TYPE for a void return type, or the Class of the type.

    - #### getModifiers

          public Modifiers getModifiers()

    - #### getName

          public java.lang.String getName()

    - #### invoke

          public java.lang.Object invoke(java.lang.Object[] argValues,
                                Interpreter interpreter)
                                  throws EvalError

      Invoke the declared method with the specified arguments and interpreter reference. This is the simplest form of invoke() for BshMethod intended to be used in reflective style access to bsh scripts.
      Throws:
        `EvalError`

    - #### invoke

          public java.lang.Object invoke(java.lang.Object[] argValues,
                                Interpreter interpreter,
                                CallStack callstack,
                                org.gjt.sp.jedit.bsh.SimpleNode callerInfo)
                                  throws EvalError

      Invoke the bsh method with the specified args, interpreter ref, and callstack. callerInfo is the node representing the method invocation It is used primarily for debugging in order to provide access to the text of the construct that invoked the method through the namespace.
      Parameters:
        `callerInfo` - is the BeanShell AST node representing the method invocation. It is used to print the line number and text of errors in EvalError exceptions. If the node is null here error messages may not be able to point to the precise location and text of the error.
        `callstack` - is the callstack. If callstack is null a new one will be created with the declaring namespace of the method on top of the stack (i.e. it will look for purposes of the method invocation like the method call occurred in the declaring (enclosing) namespace in which the method is defined).
      Throws:
        `EvalError`

    - #### hasModifier

          public boolean hasModifier(java.lang.String name)

    - #### toString

          public java.lang.String toString()

      Overrides:
        `toString` in class `java.lang.Object`
