getLocals	back to summary
public Object[] getLocals() Implements java.lang.LiveStackFrame.getLocals. Doc from java.lang.LiveStackFrame.getLocals. Gets the local variable array of this stack frame. A single local variable can hold a value of type boolean, byte, char, short, int, float, reference or returnAddress. A pair of local variables can hold a value of type long or double (JVMS section 2.6.1). Primitive locals are represented in the returned array as `PrimitiveSlot`s, with longs and doubles occupying a pair of consecutive `PrimitiveSlot`s. The current VM implementation does not provide specific type information for primitive locals. This method simply returns the raw contents of the VM's primitive locals on a best-effort basis, without indicating a specific type. The returned array may contain null entries for local variables that are not live. Annotations @Override
