Method Detail

computeConstantValueback to summary
private TypedValue computeConstantValue()

If all the components of the map are constants, or lists/maps that themselves contain constants, then a constant map can be built to represent this node.

This will speed up later getValue calls and reduce the amount of garbage created.
