Method Details

getArgumentValue

public ArgumentValue getArgumentValue(String argName)

Look up an argument by name only, for cases in which we do not have the full argument definition, such as arguments used for defining the length of other variable-length arguments.

Parameters:

argName - the name of the argument

Returns:

the argument value, if found, or null

getAggregateReference

public TcProcessingContext.AggregateWithValue getAggregateReference(String argName)

Lookup the argument by name in the stack of aggregates

The returned AggregateWithValue may not have the value set

Parameters:

argName - the name of the aggregate member to look up

Returns:

the argument value, if found, or null

getRawParameterValue

public Value getRawParameterValue(Parameter param)

getArgValues

public Map<Argument,ArgumentValue> getArgValues()

hasArgumentValue

public boolean hasArgumentValue(Argument a)

pushCurrentAggregate

public void pushCurrentAggregate(TcProcessingContext.AggregateWithValue newAggregate)

Pushes a new current aggregate onto the stack.

Parameters:

newAggregate - the aggregate to push

popCurrentAggregate

public TcProcessingContext.AggregateWithValue popCurrentAggregate()

Pops the current aggregate from the stack and returns it.

Returns:

the previous current aggregate, or null if the stack is empty

addArgumentValue

public void addArgumentValue(Argument a,
 Value argValue)

getArgument

public Argument getArgument(String argName)

getSize

public int getSize()

setSize

public void setSize(int size)

sets the size in bytes of the encoded command

getCommand

public MetaCommand getCommand()

returns the size in bytes of the encoded command
