java.lang.Objectcom.crystaldecisions.sdk.occa.report.data.Field
com.crystaldecisions.sdk.occa.report.data.ParameterField
This object enables you to get and set values
for the parameter field. When possible, use the
IParameterField
interface to manipulate this object.
Parameters prompt the user of a report to enter information.
Think of a parameter as a question that the user needs to answer before the report is generated. The information users enter, or the way they respond, determines what appears in the report. For example, in a report used by sales people, there might be a parameter that asks the user to choose a region. The report would return the results for the specific region instead of returning the results for all of the regions.
By using parameter fields in formulas, selection formulas, and in the report itself, you can create a single report that you can modify whenever your needs change. Parameter fields can also be used in subreports. Parameter values are discrete or ranged. A discrete value represents a particular, single value, while a range value represents a value between a certain range. Additionally, parameters can have one value (discrete or ranged) or multiple values (discrete or ranged).
The ParameterField
object allows you to manipulate
a parameter in the report.

object.public java.lang.String getEditMask()
IParameterField
Returns the edit mask for the parameter values. This is used for UI-display purposes. The edit mask can be any of a set of masking characters used to restrict the values you can enter as parameter values. The edit mask also limits the values you can enter as default prompting values.
Note: The value of the edit mask is not checked if you use the SDK to change parameter values. You must check to ensure that any values the user enters respect the edit mask. If a user enters an invalid value according to the edit mask, it will not be possible to view or schedule the report.
The edit mask follows the following guidelines:
Note: Some of the edit mask characters require that you enter a character in their place (when entering a parameter value), while others allow you to leave a space, if needed. For example, if the edit mask is 000099, you can enter a parameter value with four digits, five digits, or six digits, since the '9' edit mask character does not require the entry of a character. However, since '0' does require such an entry, you could not enter a parameter value with less than four digits.

.public FieldKind getKind()

Returns the maximum value the parameter can have, providing that a minimum value is also specified.
If the parameter is discrete, the discrete values must be between the minimum and maximum values. If the parameter has a range limit, both the maximum and minimum values are defined. The BeginValue and/or EndValue of each ranged value must be between the minimum and maximum values.
If the parameter is a number, this property represents the largest allowable number the parameter may have. If it is a string, this is the maximum length the string may be. If it is a Date/Time value, this is the earliest date and time the parameter may be. This property does not apply to Boolean values.
