  • Field Details

    • EMPTY_EXPRESSION_ARRAY

      static final IASTExpression[] EMPTY_EXPRESSION_ARRAY
      Empty expression array.

  • Method Details

    • getExpressionType

      IType getExpressionType()
      Returns the type of the value the expression evaluates to.

    • isLValue

      boolean isLValue()
      Returns whether this expression is an lvalue. LValues are for instance required on the left hand side of an assignment expression.
      Since:
      5.2

    • getValueCategory

      IASTExpression.ValueCategory getValueCategory()
      Returns the value category of this expression.
      Since:
      5.3

    • copy

      IASTExpression copy()
      Description copied from interface: IASTNode
      Returns a mutable copy of the tree rooted at this node. The following postconditions hold: 
       copy.getParent() == null
 copy.getPropertyInParent() == null
 copy.isFrozen() == false
      Preprocessor nodes do not currently support being copied. Implicit name nodes are not copied, instead they can be regenerated if required.

      Calling this method is equivalent to copy(CopyStyle.withoutLocations).

    • copy

      IASTExpression copy(IASTNode.CopyStyle style)
      Description copied from interface: IASTNode
      Returns a mutable copy of the tree rooted at this node. The following postconditions hold: 
       copy.getParent() == null
 copy.getPropertyInParent() == null
 copy.isFrozen() == false
      Preprocessor nodes do not currently support being copied. Implicit name nodes are not copied, instead they can be regenerated if required.
      Specified by:
      copy in interface IASTInitializerClause
      Specified by:
      copy in interface IASTNode
      Parameters:
      style - IASTNode.CopyStyle create a copy with or without locations. Please see IASTNode.CopyStyle for restrictions on copies with Locations.
