  - ### Methods Summary

    Methods
    Type Params | Return Type | Name and description
    --- | --- | ---
    `` | `Expression` | `getArguments()`
    `` | `GenericsType[]` | `getGenericsTypes()`
    `` | `Expression` | `getMethod()`
    `` | `String` | `getMethodAsString()` This method returns the method name as String if it is no dynamic calculated method name, but a constant.
    `` | `MethodNode` | `getMethodTarget()` @return the target as method node if set
    `` | `Expression` | `getObjectExpression()`
    `` | `ASTNode` | `getReceiver()`
    `` | `String` | `getText()`
    `` | `boolean` | `isImplicitThis()` @return true if no object expression was specified otherwise if some expression was specified for the object on which to evaluate the method then return false
    `` | `boolean` | `isSafe()` @return is this a safe method call, i.e. if true then if the source object is null then this method call will return null rather than throwing a null pointer exception

  - ### Method Detail

    - #### public Expression getArguments()

    - #### public GenericsType[] getGenericsTypes()

    - #### public Expression getMethod()

    - #### public String getMethodAsString()

      This method returns the method name as String if it is no dynamic calculated method name, but a constant.

    - #### public MethodNode getMethodTarget()

      Returns:
        the target as method node if set

    - #### public Expression getObjectExpression()

    - #### public ASTNode getReceiver()

    - #### public String getText()

    - #### public boolean isImplicitThis()

      Returns:
        true if no object expression was specified otherwise if some expression was specified for the object on which to evaluate the method then return false

    - #### public boolean isSafe()

      Returns:
        is this a safe method call, i.e. if true then if the source object is null then this method call will return null rather than throwing a null pointer exception

    - #### public boolean isSpreadSafe()

    - #### public boolean isUsingGenerics()

    - #### public void setArguments(Expression arguments)

    - #### public void setGenericsTypes(GenericsType[] genericsTypes)

    - #### public void setImplicitThis(boolean implicitThis)

    - #### public void setMethod(Expression method)

    - #### public void setMethodTarget(MethodNode mn)

      Sets a method call target for a direct method call. WARNING: A method call made this way will run outside of the MOP!

      Parameters:
        `mn` - the target as MethodNode, mn==null means no target
