question: get the leaf child of this continuationstate . when mediate using the continuationstatestack , first we start from the lead child of the continuationstate . concode_field_sep ContinuationState childContState concode_elem_sep int position concode_field_sep int getPosition concode_elem_sep void addLeafChild concode_elem_sep boolean hasChild concode_elem_sep void removeLeafChild concode_elem_sep ContinuationState getChildContState concode_elem_sep void setChildContState concode_elem_sep void setPosition
target: ContinuationState function ( ) { if ( this . hasChild ( ) ) { return childContState . getLeafChild ( ) ; } else { return this ; } }
