public boolean isCanSendAid()

This routine is used to check if we can send the Aid key to the host Taken from Section 16.2.1.2 Enter/Rec Adv Key In the normal unlocked state, when the workstation operator presses the Enter/Rec Adv key: 1. The 5494 checks for the completion of mandatory-fill, self-check, and right-adjust fields when in an active field. (An active field is one in which the workstation operator has begun entering data.) If the requirements of the field have not been satisfied, an error occurs.

Returns:

findByString

public ScreenField findByString(String targetString,
                                int startPos,
                                int length,

                                boolean ignoreCase)

Searches the collection for the target string and returns the iOhioField object containing that string. The string must be totally contained within the field to be considered a match.

Parameters:

targetString - The target string.

startPos - The row and column where to start the search. The position is inclusive (for example, row 1, col 1 means that position 1,1 will be used as the starting location and 1,1 will be included in the search).

length - The length from startPos to include in the search.

dir - An OHIO_DIRECTION value:

ignoreCase - flag

summary

Constant	Value	Description
OS_OHIO_DIRECTION_FORWARD	0	Forward (beginning towards end)
OS_OHIO_DIRECTION_BACKWARD	1	Backward (end towards beginning)

Constant Value Description ignoreCase - Indicates whether the search is case sensitive. True means that case will be ignored. False means the search will be case sensitive.

Returns:

If found, an iOhioField object containing the target string. If not found, returns a null.

findByPosition

public ScreenField findByPosition(int targetPosition)

Searches the collection for the target position and returns the ScreenField object containing that position.

Parameters:

targetPosition - The target row and column expressed as a linear position within the presentation space.

Returns:

If found, a ScreenField object containing the target position. If not found, returns a null.

findByPosition

public ScreenField findByPosition(int row,
                                  int col)

Searches the collection for the target position and returns the ScreenField object containing that position.

Parameters:

row - The beginning row to start search with in the presentation space.

col - The beginning column to start search with in the presentation space.

Returns:

If found, a ScreenField object containing the target position. If not found, returns a null.
