Constructor Detail

Asn1PerTraceHandler

protected Asn1PerTraceHandler(Asn1PerMessageBuffer messageBuffer)

This constructor initializes internal trace handler member variables.

Parameters:

messageBuffer - PER message buffer object reference

Method Detail

addElemName

public void addElemName(java.lang.String name,
                        int arrayx)

This method adds an element name to the current fully qualified name. The fully qualified name is a string of name components separated by dots (ex. a.b.c).

Parameters:

name - Name component to append to string

enable

public abstract void enable()

This method is used to turn PER bit tracing on or off

getBitFieldList

public Asn1PerBitFieldList getBitFieldList()

This method returns a reference to the bit field list

newBitField

public void newBitField(java.lang.String name,
                        int bitCount)

This method creates a new bit field and appends it to the bit field list.

Parameters:

name - Name suffix to append to the current fully qualified name.

bitCount - Number of bits in the bit field.

print

public abstract void print(java.io.PrintStream out,
                           java.lang.String varName)

This method prints the trace to the given output stream in a default format.

Parameters:

out - Print stream to which output is to be written.

varName - Name of the object variable being printed.

removeLastElemName

public void removeLastElemName()

This method removes the last element name int the current fully qualified name string. For example, if the current string is 'a.b.c', it will be 'a.b' after calling this method.

reset

public abstract void reset()

This method resets the trace bit field list.

setBitCount

public void setBitCount()

This method sets the bit count within the current bit field to the difference between the current but offset and the starting bit offset currently stored in the field object.

setBitOffset

public void setBitOffset()

This method sets the bit offset within the current bit field to the current offset within the PER message buffer.
