Constructor Detail

ColumnList

public ColumnList(@Nonnull
                  Class<T> rootClass,
                  @Nonnull
                  ClassMetaModel cmm)

Method Detail

size

public int size()

add

public void add(@Nonnull
                ColumnDef<T,?> cd)

get

@Nonnull
public ColumnDef<T,?> get(int ix)

setDefaultSortColumn

public void setDefaultSortColumn(@Nullable
                                 String sort)

Set the default sort column by property name. If it is null the default sort is undone.

Parameters:

sort -

setSortColumn

public void setSortColumn(@Nullable
                          ColumnDef<T,?> cd,
                          @Nullable
                          SortableType type)

setSortColumn

public void setSortColumn(@Nullable
                          ColumnDef<T,?> cd)

addDefaultColumns

public void addDefaultColumns()

Add all of the columns as defined by the metadata to the list.

assignPercentages

public void assignPercentages()

Width calculations: this tries to assign widths to columns that have no explicit width assigned. It starts by calculating all assigned widths in percents and in pixels. It then calculates widths for the columns that have no widths assigned.

iterator

@Nonnull
public Iterator<ColumnDef<T,?>> iterator()

Return the iterator for all elements.

Specified by:

iterator in interface Iterable<ColumnDef<T,?>>

See Also:

Iterable.iterator()

indexOf

public int indexOf(@Nonnull
                   ColumnDef<T,?> scd)

getSortColumn

@Nullable
public ColumnDef<T,?> getSortColumn()

updateDefaultSort

protected void updateDefaultSort(@Nonnull
                                 ColumnDef<T,?> scd)

isSortDescending

public boolean isSortDescending()

setSortDescending

public void setSortDescending(boolean desc)

column

@Nonnull
public <V> ColumnDef<T,V> column(@Nonnull
                                          Class<V> type,
                                          @Nonnull
                                          String property)

Add and return the column definition for a column on the specified property. Because Java still has no first-class properties (sigh) you need to pass in the property's type to get a typeful column. If you do not need a typeful column use column(String).

Parameters:

type -

property -

Returns:

column

@Nonnull
public ColumnDef<T,?> column(@Nonnull
                                      String property)

This adds a column on the specified property, but has no idea about the real type. It can be used as long as that type is not needed.

Parameters:

property -

Returns:

column

@Nonnull
public ColumnDef<T,T> column()

Add a column which gets referred the row element instead of a column element. This is normally used together with

Returns:
