Method Summary

Modifier and Type	Method and Description
void	dissect(Parsable<?> parsable, String inputname) This method must dissect the provided field from the parsable into 'smaller' pieces.
abstract void	dissect(Parsable<?> parsable, String inputname, Value value)
String	getInputType()
List<String>	getPossibleOutput() What are all possible outputs that can be provided.
protected void	initializeNewInstance(Dissector newInstance) This is called after instantiating the class that is actually in the parsetree.
EnumSet<Casts>	prepareForDissect(String inputname, String outputname) This tells the dissector that it should prepare that we will call it soon with 'inputname' and expect to get 'inputname.outputname' because inputname is of the type returned by getInputType and outputname was part of the answer from getPossibleOutput.
void	setInputType(String nInputType)

Constructor Detail

SimpleDissector

public SimpleDissector(String inputType,
                       Map<String,EnumSet<Casts>> outputTypes)

Method Detail

getInputType

public String getInputType()

Specified by:

getInputType in class Dissector

Returns:

The required typename of the input

setInputType

public void setInputType(String nInputType)

Overrides:

setInputType in class Dissector

getPossibleOutput

public List<String> getPossibleOutput()

Description copied from class: Dissector

What are all possible outputs that can be provided.

Specified by:

getPossibleOutput in class Dissector

Returns:

array of "type:name" values that indicates all the possible outputs. Never a null!

prepareForDissect

public EnumSet<Casts> prepareForDissect(String inputname,
                                        String outputname)

Description copied from class: Dissector

This tells the dissector that it should prepare that we will call it soon with 'inputname' and expect to get 'inputname.outputname' because inputname is of the type returned by getInputType and outputname was part of the answer from getPossibleOutput. This can be used by the dissector implementation to optimize the internal parsing algorithms and lookup tables and such. The dissector must return the types to which this value can be mapped later on during the run.

Specified by:

prepareForDissect in class Dissector

Returns:

The EnumSet of all allowed casts. Returns an empty EnumSet if nothing is allowed. Never a null !

initializeNewInstance

protected void initializeNewInstance(Dissector newInstance)
                              throws InvalidDissectorException

Description copied from class: Dissector

This is called after instantiating the class that is actually in the parsetree.

Overrides:

initializeNewInstance in class Dissector

Parameters:

newInstance - The new instances of this class that must be initialized

Throws:

InvalidDissectorException

dissect

public final void dissect(Parsable<?> parsable,
                          String inputname)
                   throws DissectionFailure

Description copied from class: Dissector

This method must dissect the provided field from the parsable into 'smaller' pieces.

Specified by:

dissect in class Dissector

Throws:

DissectionFailure

dissect

public abstract void dissect(Parsable<?> parsable,
                             String inputname,
                             Value value)
                      throws DissectionFailure

Throws:

DissectionFailure
