Detailed Description

A context blob, holding context values across some range of code addresses.

This is an internal object that allocates the actual "array of words" for a context blob. An associated mask array holds 1-bits for context variables that were explicitly set for the specific split point.

ContextInternal::FreeArray & ContextInternal::FreeArray::operator=

(

const FreeArray &

op2

)

Assignment operator.

Clone a context blob into this.

Parameters

op2	is the context blob being cloned/copied

Returns

a reference to this

void ContextInternal::FreeArray::reset

(

int4

sz

)

Resize the context blob, preserving old values.

The "array of words" and mask array are resized to the given value. Old values are preserved, chopping off the last values, or appending zeroes, as needed.

Parameters

sz	is the new number of words to resize array to
