public class PartialCall extends Expression
A lambda (anonymous function) representing a partial call of some kind of function

  • Field Details

    • parameters

      public final Field[] parameters
      The lambda parameters

    • body

      public final Expression body
      The body of the lambda

    • returnType

      public final Type returnType
      The return type of the lambda

    • interfaceType

      public final Type interfaceType
      The type of the interface representing the lambda

    • interfaceMethodName

      public final String interfaceMethodName
      The name of the method in the lambda's interface

    • parameterTypes

      public Type[] parameterTypes
      The types of the lambda parameters

    • useObjectInterface

      public final boolean useObjectInterface
      If true, the interface describing this lambda should use objects instead of native types. This allows it to be compatible with the java.util.function package

    • partialArguments

      public final Expression[] partialArguments
      The arguments that have already been supplied for the function call

  • Constructor Details

    • PartialCall

      public PartialCall(Field[] parameters, Type returnType, Expression[] partialArguments, Expression body)
      Create a partial call lambda expression
      Parameters:
      parameters - The lambda parameters and their types
      returnType - The lambda return type
      partialArguments - The arguments that have already been supplied to the function
      body - The body of the lambda

    • PartialCall

      public PartialCall(Field[] parameters, Type returnType, Expression[] partialArguments, Expression body, String filename, int lineNumber)
      Create a partial call lambda expression
      Parameters:
      parameters - The lambda parameters and their types
      returnType - The lambda return type
      partialArguments - The arguments that have already been supplied to the function
      body - The body of the lambda
      filename - The name of the source file where this partial call is defined
      lineNumber - The line number in the source file where this partial call is defined

  • 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
