    • TYPE_ARGUMENTS_PROPERTY

      public static final ChildListPropertyDescriptor TYPE_ARGUMENTS_PROPERTY
      The "typeArguments" structural property of this node type (element type: Type) (added in JLS3 API).
      Since:
      3.1

    • NAME_PROPERTY

      public static final ChildPropertyDescriptor NAME_PROPERTY

  • Method Details

    • propertyDescriptors

      public static List propertyDescriptors(int apiLevel)
      Returns a list of structural property descriptors for this node type. Clients must not modify the result.
      Parameters:
      apiLevel - the API level; one of the AST.JLS* constants
      Returns:
      a list of property descriptors (element type: StructuralPropertyDescriptor)
      Since:

    • getExpression

      public Expression getExpression()
      Returns the expression of this method invocation expression, or null if there is none.
      Returns:
      the expression node, or null if there is none

    • isResolvedTypeInferredFromExpectedType

      public boolean isResolvedTypeInferredFromExpectedType()
      Returns true if the resolved return type has been inferred from the assignment context (JLS3 15.12.2.8), false otherwise.

      This information is available only when bindings are requested when the AST is being built

      .
      Returns:
      true if the resolved return type has been inferred from the assignment context (JLS3 15.12.2.8), false otherwise
      Since:
      3.3

    • setExpression

      public void setExpression(Expression expression)
      Sets or clears the expression of this method invocation expression.
      Parameters:
      expression - the expression node, or null if there is none
      Throws:
      IllegalArgumentException - if:
      • the node belongs to a different AST
      • the node already has a parent
      • a cycle in would be created

    • typeArguments

      public List typeArguments()
      Returns the live ordered list of type arguments of this method invocation (added in JLS3 API).
      Returns:
      the live list of type arguments (element type: Type)
      Throws:
      UnsupportedOperationException - if this operation is used in a JLS2 AST
      Since:
      3.1

    • getName

      public SimpleName getName()
      Returns the name of the method invoked in this expression.
      Returns:
      the method name node

    • setName

      public void setName(SimpleName name)
      Sets the name of the method invoked in this expression to the given name.
      Parameters:
      name - the new method name
      Throws:
      IllegalArgumentException - if:
      • the node belongs to a different AST
      • the node already has a parent

    • arguments

      public List arguments()
      Returns the live ordered list of argument expressions in this method invocation expression.
      Returns:
      the live list of argument expressions (element type: Expression)

    • resolveMethodBinding

      public IMethodBinding resolveMethodBinding()
      Resolves and returns the binding for the method invoked by this expression.

      Note that bindings are generally unavailable unless requested when the AST is being built.

      Returns:
      the method binding, or null if the binding cannot be resolved
