public class ParameterFieldDiscreteValue
extends ParameterFieldValue
implements IParameterFieldDiscreteValue, IClone

This object represents a discrete value belonging to a parameter. A discrete value is a value that does not have a range--that is, it is singular. Examples of discrete values are: 1, 56.4, "Jeremy", and so on. When possible, use the interfaces IParameterFieldValue and IValue to manipulate this object.

Method Detail

clone

public java.lang.Object clone(boolean deepClone)
Specified by:
clone in class ParameterFieldValue

computeText

public java.lang.String computeText()
Description copied from interface: IValue

The ComputeText method returns a String representation of the field value that can be used in a report formula.

The String is not formatted or localized. The syntax will always be Crystal syntax. If the field contains a date, ComputeText returns Date(x, x, x); if it contains a date and time, ComputeText returns DateTime(x, x, x, x, x, x). However, when the date is 1900, 0, 1 (the Java start date), ComputeText returns Time(x, x, x). If you want to set a field to a time value only (that is, with no date), you should set the date to 1900, 0, 1, so that ComputeText will retrieve the correct information.

Specified by:
computeText in interface IValue
Specified by:
computeText in class Value
Returns:
A String representation of the field value that can be used in a report formula.

copyTo

public void copyTo(java.lang.Object destObject,
                   boolean deepCopy)
Overrides:
copyTo in class ParameterFieldValue

createMember

public java.lang.Object createMember(java.lang.String eleName,
                                     org.xml.sax.Attributes attrs,
                                     XMLSerializationContext ctxt,
                                     java.util.Map objState,
                                     boolean[] bLoaded)
Description copied from class: Value

For internal use only.

Overrides:
createMember in class ParameterFieldValue

displayText

public java.lang.String displayText(java.util.Locale locale)
Description copied from interface: IValue

Returns the field's value as a localized and formatted String. The Locale can be a java.util.Locale value.

The value is formatted according to the locale. The user is required to pass in a locale; the system default locale or user default locale is not used. If the field contains a date, displayText returns a locale-specific date string; if it contains a date and time, displayText returns a locale-specific date time String; if it contains a time String, displayText returns a locale-specific time String.

Specified by:
displayText in interface IValue
Specified by:
displayText in class Value
Parameters:
locale - The locale as specified by java.util.Locale .
Returns:
The field's value as a localized and formatted String.

endElement

public void endElement(java.lang.String eleName,
                       java.util.Map objState)
Description copied from class: Value

For internal use only.

Overrides:
endElement in class ParameterFieldValue

getValue

public java.lang.Object getValue()
Description copied from interface: IParameterFieldDiscreteValue

Returns the discrete value of the parameter.

Specified by:
getValue in interface IParameterFieldDiscreteValue
Returns:
The value as an object.

hasContent

public boolean hasContent(java.lang.Object srcParameterFieldDiscreteValue)

                        java.util.Map objState)
Description copied from class: Value

For internal use only.

Overrides:

          throws java.io.IOException
Description copied from class: Value

For internal use only.

Overrides:
save in class ParameterFieldValue
Throws:
java.io.IOException

saveContents

public void saveContents(XMLWriter writer,

Description copied from class: Value

For internal use only.

Overrides:
saveContents in class ParameterFieldValue
Throws:
java.io.IOException

setValue

public void setValue(java.lang.Object value)
Description copied from interface: IParameterFieldDiscreteValue

Specified by:
setValue in interface IParameterFieldDiscreteValue
Parameters:
value - The value as an object.

startElement
