Field Detail

pointerindex

public boolean pointerindex

The pointerindex boolean describes whether the Temp induction variable is a pointer [true] or an integer [false].

ptrvariable

objectsize

public HClass objectsize

The objectsize HClass saves the array type.

pointeroffset

public ArrayList pointeroffset

The ArrayList saves pointer Temps that are added in.

copied

public boolean copied

Method Detail
