Method Details

write

public void write(BytecodeSerialization out)
           throws IOException

Throws:

IOException

getInParameter

public int getInParameter()

getOutParameter

public int getOutParameter()

getParameterKind

public int getParameterKind(int index)

Specified by:

getParameterKind in class Pattern

createMatcher

public Pattern.Matcher createMatcher(Graph src,
 XBitSet providedConstants,
 IntList neededConstantsOut)

Creates a Matcher object for this CompoundPattern instance.

Specified by:

createMatcher in class Pattern

Parameters:

src - the runtime graph in which the created matcher will search for matches

providedConstants - specifies which parameters are already bounded

neededConstantsOut - specifies which parameters need to be bounded

Returns:

Matcher object that can find matches in the graph

isDeleting

public boolean isDeleting()

Overrides:

isDeleting in class Pattern

getTotalParameterCount

public final int getTotalParameterCount()

forceAllParamContext

public void forceAllParamContext(boolean b)

getPredicates

public Pattern[] getPredicates()

paramString

protected String paramString()

Overrides:

paramString in class Pattern

getPlaceForLocalMap

public short[] getPlaceForLocalMap()

This map contains the mapping between the signature variable to the declared QV place. The signature variables are assumed to be in order of their declaration in the method signature. Used for UserDefinedCompoundPattern.

setPlaceForLocalMap

public void setPlaceForLocalMap(short[] m)
