Citrix Systems Network Router 9.2 ユーザーズマニュアル

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

number.TYPECAST_TIME_AT

and operators of the format 
"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).

Transform, extract, and evaluate time 
values.

Operators of the format "double.<operator>."

For example, double.ADD (i), 
double.BETWEEN(i, j), and double.DIV(i).

Extract and evaluate double-precision 
floating-point numeric data.

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), 
text.GET_SIGNED32(n, endianness), 
text.GET_SIGNED8(n), 
text.GET_UNSIGNED16(n, endianness), 
and text.GET_UNSIGNED8(n)

Extract a series of bytes that represent a 
sequence of 8, 16, or 32 bit integers (signed 
or unsigned), and the extract the nth integer 
from the sequence.

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
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)

Set the mode of a text object.

.B64DECODE and .B64ENCODE

Encode and decode text by using the 
Base64 encoding algorithm.

.HASH

Convert text to a hash value.
