Constructor Detail

AVMComposer

public AVMComposer()
            throws java.net.MalformedURLException

Creates AVMComposer with a list of prototypes (avmStructures) of different typed AVMs and a local list of composed AVMs (avmList).

Throws:

java.net.MalformedURLException

AVMComposer

public AVMComposer(java.lang.String worldFile)
            throws java.net.MalformedURLException

Creates AVMComposer with a list of prototypes (avmStructures) of different typed AVMs and a local list of composed AVMs (avmList). Defaults to res/PentoAVMStructures for structure file.

Parameters:

worldFile - with list of AVMs in the world.

Throws:

java.net.MalformedURLException

AVMComposer

public AVMComposer(java.lang.String structureFile,
                   java.lang.String worldFile)
            throws java.net.MalformedURLException

Creates AVMComposer with a list of prototypes (avmStructures) of different typed AVMs and a local list of composed AVMs (avmList).

Parameters:

structureFile - with list of AVMstucture

worldFile - with list of AVMs in the world

Throws:

java.net.MalformedURLException

AVMComposer

public AVMComposer(AVMComposer c)

Method Detail

compose

public java.util.ArrayList<AVM> compose(AVPair avp)

Method to call when a new AVPair becomes known. Attempt unification with known AVM prototypes (from avmStructures) which incrementally grow with more input.

Parameters:

avp -

composeAll

public void composeAll(java.util.List<AVPair> avPairs)

Calls compose() for the list of AVPairs

Parameters:

avPairs - list of AVPairs to be composed

resolve

public java.util.ArrayList<AVM> resolve()

Method to resolve composed AVMs in avmList with known AVMs in worldList. Loops through both and attempts unification.

Returns:

resolveList the new list of resolved AVMs

uniquelyResolve

public AVPair uniquelyResolve()

Resolves AVMs, returns only a single AVPair of one AVM if one was resolved (else null).

Returns:

AVPair of AVM that resolved

getResolvedList

public java.util.ArrayList<AVM> getResolvedList()

Returns list of resolved AVMs (ones with which input AVPairs could be unified.)

Returns:

list of resolved AVMs

getAllAVMs

public java.util.ArrayList<AVM> getAllAVMs()

Returns list of AVMs known from AVM structures.

setAllAVMs

public void setAllAVMs()

Sets prototype AVMs to be used for matching against (e.g. from new AVPairs). getAllAVMs() sets these from known structures.

setAVMs

public void setAVMs(java.lang.String type)

Sets only one type of AVM by creating a compose list of only that type.

Parameters:

type -

unsetAVMs

public void unsetAVMs(java.lang.String type)

Unsets AVM of a given type by removing them from avmList list.

Parameters:

type -

printAVMs

private void printAVMs()

Prints out all known AVMs.

getAvmList

public java.util.ArrayList<AVM> getAvmList()

Returns:

the avmList

setAvmList

public void setAvmList(java.util.ArrayList<AVM> avmList)

Parameters:

avmList - the avmList to set

interactiveTest

static void interactiveTest()
                     throws java.io.IOException

Throws:

java.io.IOException

main

public static void main(java.lang.String[] args)
                 throws java.io.IOException

Main method mostly for local testing.

Parameters:

args -
