Method Details

determineSignatureOffsetDict

static int determineSignatureOffsetDict(byte[] _sigb,
 int _currentOffset)

This function determine the new offset in signature for empty Dictionary/Map collections. Normally the element inside a collection determines the new offset, however in case of empty collections there is no element to determine the sub signature of the list so this function determines which part of the signature to skip

Parameters:

_sigb - the total signature

_currentOffset - the current offset within the signature

Returns:

the index of the last element of the collection (subtype)

determineSignatureOffsetArray

static int determineSignatureOffsetArray(byte[] _sigb,
 int _currentOffset)

This function determine the new offset in signature for empty Array/List collections. Normally the element inside a collection determines the new offset, however in case of empty collections there is no element to determine the sub signature of the list so this function determines which part of the signature to skip

Parameters:

_sigb - the total signature

_currentOffset - the current offset within the signature

Returns:

the index of the last element of the collection (subtype)

determineSignatureOffsetStruct

private static int determineSignatureOffsetStruct(byte[] _sigb,
 int _currentOffset)

determineEndOfBracketStructure

private static int determineEndOfBracketStructure(byte[] _sigb,
 int _currentOffset,
 char _openChar,
 char _closeChar)

This is a generic function to determine the end of a structure that has opening and closing characters. Currently used for Struct () and Dict {}

determineSubSignature

private static String determineSubSignature(byte[] _sigb,
 int _currentOffset)

determineCollectionSubType

private static EmptyCollectionHelper.ECollectionSubType determineCollectionSubType(char _sig)

The starting type determines of a collection determines when it ends

Parameters:

_sig - the signature letter of the type
