The byte sequence indicating use of Ion 1.0 binary format.

The number of bytes in BINARY_VERSION_MARKER_1_0.

maximum size of textual representation of a long.

Prefix string used in IonStructs' equality checks. When a IonValue's field name's text is unknown, this String is prepended to the field name's SID to coerce it to a string to be used as the key. This will eliminate collisions with IonValues with numbers as their field names.

For example, these two IonValues (nested in the IonStructs) will have distinct keys:

{"$99":random_value},
{$99:random_value}

TODO amazon-ion/ion-java/issues/23 However, there is still a potential failure if one of the IonStruct's nested value has a field name with text " -- UNKNOWN SYMBOL TEXT -- $123", and that another nested value of an IonStruct has a field name with unknown text and sid 123, these two values will be considered a match within IonStruct's equality checks, which is wrong.

See IonAssert for another use of this idiom.

Extract the type code (high nibble) from a type descriptor.

Parameters

td:int

must be a positive int between 0x00 and 0xFF.

Returns:int

the high nibble of the input byte, between 0x00 and 0x0F.

Make a type descriptor from two nibbles; all of which are represented as ints.

Parameters

highNibble:int

must be a positive int between 0x00 and 0x0F.

lowNibble:int

must be a positive int between 0x00 and 0x0F.

Returns:int

the combined nibbles, between 0x00 and 0xFF.
