advances the bit position to the specified alignment.
advances the bit position to the specified alignment.
Note that the bitAlignment1b argument is 1-based.
Passing 0 as the argument is a usage error.
Passing 1 as the argument performs no alignment, as any bit position is 1-bit aligned.
For any other value, the bit position (1-based) is advanced to the next multiple of that argument value.
False is returned if there are insufficient available bits to achieve the alignment.
Debugging flag.
Debugging flag. If set then performance may be reduced, but historic and upcoming data may be viewed using the pastData and futureData methods.
This should be set at the beginning of execution. If it is set after data has been accessed then IllegalStateException is thrown.
For assertion checking really.
For assertion checking really. Optimizations should remove the need for most alignment operations. This can be used in assertions that check that this is working properly.
Note that the bitAlignment1b argument is 1-based.
Passing 0 as the argument is a usage error.
Passing 1 as the argument performs no alignment, as any bit position is 1-bit aligned.
Access to historic (past data) and upcoming data for purposes of display in a trace or debugger.
Access to historic (past data) and upcoming data for purposes of display in a trace or debugger.
If areDebugging is false, these throw IllegalStateException
Returns number of bits remaining (if a limit is defined).
Returns number of bits remaining (if a limit is defined). Nope if not defined.
Allow tuning of these thresholds and starting values.
Allow tuning of these thresholds and starting values. These could, in principle, be tuned differently for different elements, thereby keeping limits small when the schema component can be determined to only require small space, but enabling larger limits/starting values when a component has larger needs.
These could be cached on, say, the ElementRuntimeData object for each element, or some other kind of dynamic cache.
Advances the bit position by nBits.
Advances the bit position by nBits. If nBits aren't available this returns false. Otherwise it returns true.
Called once after each parse operation to verify final invariants for the implementation.
Called once after each parse operation to verify final invariants for the implementation.
Use to perform checks such as that data structures held in pools are all returned before end of parse.
This is an interface trait, and it defines methods shared by both DataInputStream and DataOutputStream.
Implementation (partial) is in DataStreamCommonImplMixin.
