Constructor Detail

Group

public Group(XmlGroup group)
      throws IntakeException

Constructs a new Group based on the xml specification. Groups are instantiated and pooled by the IntakeService and should not be instantiated otherwise.

Parameters:

group - a XmlGroup value

Throws:

IntakeException - if an error occurs in other classes

Method Detail

init

public Group init(ValueParser pp)
           throws TurbineException

Initializes the default Group using parameters.

Parameters:

pp - a ValueParser value

Returns:

this Group

Throws:

TurbineException

init

public Group init(java.lang.String key,
                  ValueParser pp)
           throws IntakeException

Initializes the Group with parameters from RunData corresponding to key.

Parameters:

pp - a ValueParser value

Returns:

this Group

Throws:

IntakeException

init

public Group init(Retrievable obj)

Initializes the group with properties from an object.

Parameters:

obj - a Persistent value

Returns:

a Group value

getFieldNames

public java.lang.String[] getFieldNames()

Gets a list of the names of the fields stored in this object.

Returns:

A String array containing the list of names.

getIntakeGroupName

public java.lang.String getIntakeGroupName()

Return the name given to this group. The long name is to avoid conflicts with the get(String key) method.

Returns:

a String value

getPoolCapacity

public int getPoolCapacity()

Get the number of Group objects that will be pooled.

Returns:

an int value

getGID

public java.lang.String getGID()

Get the part of the key used to specify the group. This is specified in the key attribute in the xml file.

Returns:

a String value

getOID

public java.lang.String getOID()

Get the part of the key that distinguishes a group from others of the same name.

Returns:

a String value

getObjectKey

public java.lang.String getObjectKey()

Concatenation of gid and oid.

Returns:

a String value

getObjects

public java.util.ArrayList getObjects(ValueParser pp)
                               throws IntakeException

Describe getObjects method here.

Parameters:

pp - a ValueParser value

Returns:

an ArrayList value

Throws:

IntakeException - if an error occurs

get

public Field get(java.lang.String fieldName)
          throws IntakeException

Get the Field .

Returns:

Field.

Throws:

IntakeException - indicates the field could not be found.

isAllValid

public boolean isAllValid()

Performs an AND between all the fields in this group.

Returns:

a boolean value

setProperties

public void setProperties(java.lang.Object obj)
                   throws IntakeException

Calls a setter methods on obj, for fields which have been set.

Parameters:

obj - Object to be set with the values from the group.

Throws:

IntakeException - indicates that a failure occurred while executing the setter methods of the mapped object.

setValidProperties

public void setValidProperties(java.lang.Object obj)

Calls a setter methods on obj, for fields which pass validity tests. In most cases one should call Intake.isAllValid() and then if that test passes call setProperties. Use this method when some data is known to be invalid, but you still want to set the object properties that are valid.

getProperties

public void getProperties(java.lang.Object obj)
                   throws IntakeException

Calls getter methods on objects that are known to Intake so that field values in forms can be initialized from the values contained in the intake tool.

Parameters:

obj - Object that will be used to as a source of data for setting the values of the fields within the group.

Throws:

IntakeException - indicates that a failure occurred while executing the setter methods of the mapped object.

removeFromRequest

public void removeFromRequest()

Removes references to this group and its fields from the query parameters

resetDeclared

public void resetDeclared()

To be used in the event this group is used within multiple forms within the same template.

getHtmlFormInput

public java.lang.String getHtmlFormInput()

A xhtml valid hidden input field that notifies intake of the group's presence.

Returns:

a String value

appendHtmlFormInput

public void appendHtmlFormInput(java.lang.StringBuffer sb)

A xhtml valid hidden input field that notifies intake of the group's presence.
