Constructor Detail

RFldDatetimeArray

public RFldDatetimeArray()

Default constructor.

RFldDatetimeArray

public RFldDatetimeArray(java.lang.String name,
                         int fieldId)

Constructor.

Parameters:

name - Field name.

fieldId - Field id. Field ids must be either 0 to indicate that there is no id on the field, or greater. In addition, field ids must be unique within a messages - no two fields are allowed to have the same field id.

RFldDatetimeArray

public RFldDatetimeArray(java.lang.String name,
                         int fieldId,
                         java.lang.String desc)

Constructor.

Parameters:

name - Field name.

fieldId - Field id. Field ids must be either 0 to indicate that there is no id on the field, or greater. In addition, field ids must be unique within a messages - no two fields are allowed to have the same field id.

desc - Field description.

Method Detail

getType

public final RFldType getType()

Get field type.

Specified by:

getType in interface RFldInterface

Specified by:

getType in class RFld

Returns:

Field type STRINGARRAY.

RFldType

equals

public boolean equals(java.lang.Object anObject)

Check if another field is equal to this field. Equality is defined as the fields having the same string representation. A short cut that needs to be fixed for cases where the string representation is rounding off numbers etc.

Specified by:

equals in class RFld

Parameters:

anObject - Another field.

Returns:

true if another field is equal to this field. Otherwise, returns false.

length

public int length()

Get the number of elements in the array.

Returns:

Number of elements in the array. If the value is not set returns -1.

getElement

Get an element from the array.

Parameters:

index - Array index.

Returns:

Specified element. Returns null if the index is out of bounds or the value is not set.

See Also:

length()

hashCode

public int hashCode()

Returns the hash code value for the field.

Specified by:

hashCode in class RFld

Returns:

set in interface RFldInterface

Specified by:

set in class RFld

Parameters:

newData - New data.

Returns:

Reference to self so method chaining can be used.

Throws:

FieldValidationException

set

public RFld set(java.util.Date[] newData)
         throws FieldValidationException

Set data.

Parameters:

newData - New data.

Throws:

FieldValidationException

set

public RFld set(java.util.Hashtable newData)
         throws FieldValidationException

Set data.

Parameters:

newData - New data.

Throws:

FieldValidationException

set

public final RFld set(org.jdom.Element elem)
               throws FieldValidationException

Set the field value from a JDOM element.

Specified by:

set in interface RFldInterface

Specified by:

set in class RFld

Parameters:

elem - Field value as a JDOM element.

Returns:

Reference to self so method chaining can be used.

Throws:

FieldValidationException

validate

public void validate()
              throws FieldValidationException
