Class CallJavaConstructor

java.lang.Object

public class CallJavaConstructor extends Expression
An expression to call a Java constructor. In the Java Virtual Machine, object creation is a two-step process that requires the creation of an object via the new_object instruction, and then executing the constructor method to initialize the newly-created object. This class takes care of both of those operations.

      Create a Java constructor expression
      Parameters:
      className - The name of the class to create

    • CallJavaConstructor

      public CallJavaConstructor(String className, Type[] parameterTypes, Expression[] arguments, String filename, int lineNumber)
      Create a Java constructor expression
      Parameters:
      className - The name of the class to create
      parameterTypes - The parameter types of the constructor, in case they differ from the types of the argument expressions

  • Method Details

    • getType

      public Type getType()
      Description copied from class: Expression
      Get the type returned by this expression
      Specified by:
      getType in class Expression
      Returns:
      The type of this expression

    • reset

      public void reset()
      Description copied from class: Expression
      Resets any labels in expressions so that the method can be regenerated
      Overrides:
      reset in class Expression

    • findCaptured

      public void findCaptured(Environment env)
      Description copied from class: Expression
      Search for local variables that would be captured by a lambda. Each expression has its own implementation of this, because each subexpression must be searched.
      Specified by:
      findCaptured in class Expression
      Parameters:
      env - The environment chain to search

    • convertToFullTailCalls

      public Expression convertToFullTailCalls(boolean inTailPosition)
      Description copied from class: Expression
      Converts this expression to one that is compatible with full tail call optimization
      Specified by:
      convertToFullTailCalls in class Expression
      Parameters:
      inTailPosition - True if this expression is called from the tail position
      Returns:
      A version of this expression whose types are compatible with full tail call optimization

    • generate

      public void generate(ClassGenerator generator, Environment env, boolean inTailPosition)
      Description copied from class: Expression
      Generate the bytecode for this expression
      Specified by:
      generate in class Expression
      Parameters:
      generator - The generator for generating instructions and additional declarations
      env - The environment containing the local variables currently visible to this expression
      inTailPosition - True if this expression is being generated from the tail position of the method
