ListTable

public ListTable(java.lang.String id,
                 java.lang.String description,
                 java.util.Collection<Column<?>> columns)

Constructor.

Parameters:

id - String; id

description - String; description

columns - Collection<Column<?>>; columns

Method Detail

iterator

public java.util.Iterator<Record> iterator()

It is imperative that the user manually synchronize on the returned list when traversing it via Iterator, Spliterator or Stream when there is a risk of adding records while traversing the iterator:

  List list = Collections.synchronizedList(new ArrayList());
      ...
  synchronized (list) 
  {
      Iterator i = list.iterator(); // Must be in synchronized block
      while (i.hasNext())
          foo(i.next());
  }
 

Failure to follow this advice may result in non-deterministic behavior.

isEmpty

public boolean isEmpty()

Returns whether the table is empty.

Returns:

whether the table is empty

addRecord

public void addRecord(java.util.Map<Column<?>,java.lang.Object> data)

Adds a record to the table.

Parameters:

data - Map<String, Object>; data with values given per column

Throws:

java.lang.IllegalArgumentException - when the size or data types in the data map do not comply to the columns

addRecordByColumnIds

public void addRecordByColumnIds(java.util.Map<java.lang.String,java.lang.Object> data)

Adds a record to the table.

Parameters:

data - Map<String, Object>; data with values given per column id

Throws:

java.lang.IllegalArgumentException - when the size or data types in the data map do not comply to the columns

addRecord

public void addRecord(java.lang.Object[] data)

Adds a record to the table. The order in which the elements in the array are offered should be the same as the order of the columns.

Parameters:

data - Object[]; record data

Throws:

java.lang.IllegalArgumentException - when the size, order or data types in the Object[] do not comply to the columns
