Method Detail

debug

public static boolean debug()

Print statements in equal methods

decodeNumber

public static double decodeNumber(String s)

Decodes a String into a Double. The string can have the following formats:

      0ds :   where number is the DoubleToLongBits encoding in special format
      0d0x:   where number is the DoubleToLongBits encoding in hex
      0d# :   where number is the DoubleToLongBits encoding in hex
      0d  :   where number is the DoubleToLongBits encoding in decimal
      0x  :   where number is the Hex encoding of a Long
          :   where number contains (.Ee) and is parsed into a Double
          :   where number contains no (.Ee) and is parsed into a Long
 

decodeHex

public static long decodeHex(String s)
                      throws NumberFormatException

Decodes a non-negative Hex number into a long

Throws:

NumberFormatException

decodeSpecial

public static long decodeSpecial(String s)
                          throws NumberFormatException

Decodes a non-negative Special number into a long

Throws:

NumberFormatException

encodeSpecial

public static String encodeSpecial(long d)

main

public static void main(String[] args)

copyAttributes

public static void copyAttributes(HepRepAttribute src,
                                  HepRepAttribute dst)
                           throws CloneNotSupportedException

copy all attributes (defs and values) from node src to node dst

Throws:

CloneNotSupportedException

getType

public static HepRepType getType(Collection types,
                                 String name)

Look for hierarchical type name in Collection (Set) of types, checking its subtypes.

getInstances

public static HepRepIterator getInstances(List instanceTrees,
                                          List layers,
                                          Set types,
                                          boolean iterateFrames)

Returns an iterator which walks the full list of instances within a list of HepRepInstanceTrees

Parameters:

layers - list of layers to iteratate over or null.

iterator

public static Iterator iterator(Iterator first,
                                Iterator second)

iterates two iterations in order

getHepRepProvider

public static HepRepProvider getHepRepProvider(org.openide.util.Lookup registry,
                                               Object object)

Finds the first HepRepProvider which converts object. Return null if not found.

getHepRepConverter

public static HepRepConverter getHepRepConverter(org.openide.util.Lookup registry,
                                                 Class cls)

Deprecated. use getHepRepProvider().

Finds the first HepRepConverter which handles object. For backwards compatibility. Return null if not found.

getUnit

public static String getUnit(HepRepAttDef attDef)

Returns the Unit from the extra info. Normally the string up to the first colon, or null if extra is null.

getAllLayerNames

public static Set getAllLayerNames(HepRepInstanceTree instanceTree,
                                   boolean checkVisible,
                                   boolean checkPickable)

Returns a Set of all layernames which are used.
