### Constructor Detail

#### MethodCallExpression

    public MethodCallExpression(Expression objectExpression,
                        java.lang.String method,
                        Expression arguments)

#### MethodCallExpression

    public MethodCallExpression(Expression objectExpression,
                        Expression method,
                        Expression arguments)

### Method Detail

#### visit

    public void visit(GroovyCodeVisitor visitor)

Overrides:
  `visit` in class `ASTNode`

#### transformExpression

    public Expression transformExpression(ExpressionTransformer transformer)

Description copied from class: `Expression`
Return a copy of the expression calling the transformer on any nested expressions

Specified by:
  `transformExpression` in class `Expression`

#### getArguments

    public Expression getArguments()

#### setArguments

    public void setArguments(Expression arguments)

#### getMethod

    public Expression getMethod()

#### setMethod

    public void setMethod(Expression method)

#### getMethodAsString

    public java.lang.String getMethodAsString()

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

#### setObjectExpression

    public void setObjectExpression(Expression objectExpression)

#### getObjectExpression

    public Expression getObjectExpression()

#### getText

    public java.lang.String getText()

Overrides:
  `getText` in class `ASTNode`

#### isSafe

    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

#### setSafe

    public void setSafe(boolean safe)

#### isSpreadSafe

    public boolean isSpreadSafe()

#### setSpreadSafe

    public void setSpreadSafe(boolean value)

#### isImplicitThis

    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

#### setImplicitThis

    public void setImplicitThis(boolean implicitThis)

#### toString

    public java.lang.String toString()

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

#### getGenericsTypes

    public GenericsType[] getGenericsTypes()

#### setGenericsTypes

    public void setGenericsTypes(GenericsType[] genericsTypes)

#### isUsingGenerics

    public boolean isUsingGenerics()

#### setMethodTarget

    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

#### getMethodTarget

    public MethodNode getMethodTarget()

Returns:
  the target as method node if set
