New Operators for Extracting and Evaluating Numeric Data

Operators	Operation
number.TYPECAST_TIME_AT	Transform, extract, and evaluate time
and operators of the format	values.
"number.TYPECAST_TIME_AT.<operator>."
For example,
number.TYPECAST_TIME_AT.DAY,
number.TYPECAST_TIME_AT.BETWEEN(t
ime1, time2), and
number.TYPECAST_TIME_AT.EQ(t).
Operators of the format "double.<operator>."	Extract and evaluate double-precision
For example, double.ADD (i),	floating-point numeric data.
double.BETWEEN(i, j), and double.DIV(i).

Operators for Extracting and Evaluating Text

The following operators have been introduced for extracting and evaluating text.

New Operators for Evaluating Text

Operators	Operation
EXTEND(m,n)	Extend the scope of the search by a
	specified number of bytes on both sides of
	a pattern match.
text.GET_SIGNED16(n, endianness),	Extract a series of bytes that represent a
text.GET_SIGNED32(n, endianness),	sequence of 8, 16, or 32 bit integers (signed
text.GET_SIGNED8(n),	or unsigned), and the extract the nth integer
text.GET_UNSIGNED16(n, endianness),	from the sequence.
and text.GET_UNSIGNED8(n)
text.SUBSTR_ANY(patset_name)	Select a sub-string that matches a string in
	the given pattern set.
text.SET_TEXT_MODE(PLUS_AS_SPAC	Set the mode of a text object.
E NO_PLUS_AS_SPACE),
text.SET_TEXT_MODE(BACKSLASH_E
NCODED
NO_BACKSLASH_ENCODED), and
text.SET_TEXT_MODE(BAD_ENCODE_
RAISE_UNDEF
NO_BAD_ENCODE_RAISE_UNDEF)
.B64DECODE and .B64ENCODE	Encode and decode text by using the
	Base64 encoding algorithm.
.HASH	Convert text to a hash value.
