Method Detail

listIndex

public static CTX listIndex(int index)

Lookup list by index offset.

If the index is negative, the resolved index starts backwards from end of list. If an index is out of bounds, a parameter error will be returned. Examples:

• 0: First item.
• 4: Fifth item.
• -1: Last item.
• -3: Third to last item.

listIndexCreate

public static CTX listIndexCreate(int index,
                                  ListOrder order,
                                  boolean pad)

Lookup list by base list's index offset. If the list at index offset is not found, create it with the given sort order at that index offset. If pad is true and the index offset is greater than the bounds of the base list, nil entries will be inserted before the newly created list.

listRank

public static CTX listRank(int rank)

Lookup list by rank.

• 0 = smallest value
• N = Nth smallest value
• -1 = largest value

listValue

public static CTX listValue(Value key)

Lookup list by value.

mapIndex

public static CTX mapIndex(int index)

Lookup map by index offset.

If the index is negative, the resolved index starts backwards from end of list. If an index is out of bounds, a parameter error will be returned. Examples:

• 0: First item.
• 4: Fifth item.
• -1: Last item.
• -3: Third to last item.

mapRank

public static CTX mapRank(int rank)

Lookup map by rank.

• 0 = smallest value
• N = Nth smallest value
• -1 = largest value

mapKey

public static CTX mapKey(Value key)

Lookup map by key.

mapKeyCreate

public static CTX mapKeyCreate(Value key,
                               MapOrder order)

Lookup map by base map's key. If the map at key is not found, create it with the given sort order at that key.

mapValue

public static CTX mapValue(Value key)

Lookup map by value.

toBytes

public static byte[] toBytes(CTX[] ctx)

Serialize context array to bytes.

fromBytes

public static CTX[] fromBytes(byte[] bytes)

Deserialize bytes to context array.

toBase64

public static String toBase64(CTX[] ctx)

Serialize context array to base64 encoded string.

fromBase64

public static CTX[] fromBase64(String base64)

Deserialize base64 encoded string to context array.
