examineEntries

public abstract boolean examineEntries(SymbolObjectVisitor<T> visitor)

Examines map entries via specified SymbolObjectVisitor. Returns true if not all entries were examined (this happens when visitor.hasCapacity() return false) or false if all entries were examined.

Parameters:

visitor - SymbolObjectVisitor to use

Returns:

true, if some data left unexamined
