Member Function Documentation

Command_Element * Parse_Command_Sets::dual

(

vector< string >

str

Called when one connector connects exactly two commands.

Returns

Returns a pointer to the Command_Element which can be executed

Command_Element * Parse_Command_Sets::multi

(

vector< string >

str

)

Called when many connectors (2+) are in the submitted command.

Returns

Returns a pointer to the Command_Element which can be executed

Command_Element * Parse_Command_Sets::parse

(

)

Parses the string 'cmds' into a Command_Element* which can be executed.

Returns

Returns a pointer to the Command_Element which can be executed

Command_Element * Parse_Command_Sets::parse

(

string

input

)

Parses the string 'cmds' into a Command_Element* which can be executed.

Returns

Returns a pointer to the Command_Element which can be executed

This parsing class is the gateway between Command_Element and all other parsing classes. First the main string is ensured it isn't empty and is passed to Parse_Multiple_Commands. Based on the size of the returning vector the class sends the vector to single(), dual() or multi() which organize and create a single root command. Calling execute on this root recursively calls all other commands to emulate Bash

Command_Element * Parse_Command_Sets::single

(

string

str

)

called when no connectors are passed indicating a single command

Returns

Returns a pointer to the Command_Element which can be executed
