Parse_String

Full Library / Math Operator / Parser / Parse_String
Block Name: Parse_String

Code File Location: VisualSim/actor/lib/Parse_String

Block Overview

This actor parses an incoming string at the 'string_in' port into Java String Tokens. Spaces are used to delineate the Java String Tokens.
The Use Model is primarily bring in an incoming string, that can then be used with other blocks to create an internal 'Model_List' or 'Model_List_DS' that can be executed very fast in a simulation. The 'Parse_File' Block is similar to 'Parse_String' except it opens a file. One most likely will need to use a 'File_to_String' block to obtain the text file.
When Parse_String receives an input in the string_in port, it converst the string into a Java String Token. When the parse_string port is activated, the string is parsed to match the list of keywords provided in the keyword parameter field. When a keyword is matched, the keyword followed by the string tokens are placed on the string_output. The keyword is sent to both the keyword port and string port, when matched. An End_Of_File marker is generated on the End-of-File output port once the entire file has been parsed. A trigger is required in the parse_file input for the next string_token to be matched and placed on the output ports

The trigger can be any value. The strings in the file must be separated by space to indicate the next string.

Field Detail

public TypedIOPort string_in

public TypedIOPort parse_string

Input port and is a trigger to parse the next Java String Token. The type is general.

public TypedIOPort string_output

public TypedIOPort keyword_output

Keyword output port, for each Java String Token that matches comma separated list of keywords, sends to this port. The type is string.

public TypedIOPort end_of_string

EOF Output port, StringToken indicating end of file, which can be used to activate other blocks in the model. The type is string.
