Tap

Overview

Tap can be used for broadcasting a stream of data onto 2 or more output streams, where each stream will have different analysis and/or visualization being done on the data. It can also be used for filtering data records from the input stream by specifying an expression. It can also be used although very rarely, to join 2 streams of data.

Input Channel

One or more input channles (2 or more rarely used).

Output Channel

One or more output channel with each of them having identical data comming out of them

Properties

Property	Description	Type	Default
Filter	Reduces the number of records passed from the input to the output. The Filter can work based on values of the fields and supports the use of regular expression, which supports operators such as ==, >=, <=, >, <,	, && E.g. (Field1 > 1000) &&. (Field2 == “QDMA3”). For using regular expressions use the Like keyword in the expression E.g.(Field Like “QDMA.*). The records which meet the filter criteria will make it to the output channel	Text
Name	Displays the unique name for the component. Name can be changed through GSB	Text
Num Inputs	Number of input channels	Integer	1
Num Outputs	Number of output channels	Integer	1
Tap Flow	Not supported	Boolean	true

Example

• Input

The following records

Time	Priority	Event	Size
1000	0	ReadCmd	8
1100	0	ReadResp	8
1200	2	WriteCmd	8
1300	3	WriteCmd	8
1400	1	ReadCmd	22
1500	0	WriteCmd	8
1600	1	ReadResp	16

• Properties

These are properties changed from the default values

Property	Value
Filter	(Size==22)	(Size==16)
Num Outputs	3

• Output

Identical data streams on each of the 3 output channels having the below data

Time	Priority	Event	Size
1400	1	ReadCmd	22
1600	1	ReadResp	16
