Field Detail

• public static final BytecodeVariable SUPER_VARIABLE

  Sentinel metadata for the implicit super receiver.

• public static final BytecodeVariable THIS_VARIABLE

  Sentinel metadata for the implicit this receiver.

Constructor Detail

• public BytecodeVariable(int index, ClassNode type, String name, int prevCurrent)

  Creates bytecode metadata for a local variable slot.

  Parameters:

  index - the JVM local-variable index

  type - the variable type

  name - the variable name

  prevCurrent - the previous current-variable index

Method Detail

• public org.objectweb.asm.Label getEndLabel()

  Returns:

  the end label used for local-variable table metadata

• public int getIndex()

  Returns:

  the stack index for this variable

• public String getName()

  Returns:

  the source-level variable name

• public int getPrevIndex()

  Returns:

  the previous current-variable index

• public org.objectweb.asm.Label getStartLabel()

  Returns:

  the start label used for local-variable table metadata

• public ClassNode getType()

  Returns:

  the variable type

• public boolean isDynamicTyped()

  Returns:

  whether the variable uses dynamic typing

• public boolean isHolder()

  Returns:

  is this local variable shared in other scopes (and so must use a ValueHolder)

• public void setDynamicTyped(boolean dynamicTyped)

  Marks whether the variable should be treated as dynamically typed.

  Parameters:

  dynamicTyped - true if the variable is dynamically typed

• public void setEndLabel(org.objectweb.asm.Label endLabel)

  Sets the end label used for local-variable table metadata.

  Parameters:

  endLabel - the ending label

• public void setHolder(boolean holder)

  Marks whether this variable must be stored through a holder object.

  Parameters:

  holder - true if the variable is closure-shared

• public void setStartLabel(org.objectweb.asm.Label startLabel)

  Sets the start label used for local-variable table metadata.

  Parameters:

  startLabel - the starting label

• public void setType(ClassNode type)

  Updates the tracked variable type.

  Parameters:

  type - the new variable type

• public String toString()

  Returns a string representation of the object.

  API Note:

  In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method. The string output is not necessarily stable over time or across JVM invocations.

  Implementation Requirements:

  The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

  
  getClass().getName() + '@' + Integer.toHexString(hashCode())
  

  Returns:

  a string representation of the object.
