UnionSourceManager

public UnionSourceManager(com.fishlib.io.logger.Logger log, TableDefinition tableDefinition, @Nullable NotificationQueue.Dependency parentDependency)

Method Details

setRefreshing

public void setRefreshing()

Ensure that this UnionSourceManager will be refreshing. Should be called proactively if it is expected that refreshing DynamicTables may be added *after* the initial set, in order to ensure that children of the result table are correctly setup to listen and refresh.

setDisallowReinterpret

public void setDisallowReinterpret()

Specify that columns sources using this manager should not allow reinterpret.

allowsReinterpret

public boolean allowsReinterpret()

Determine whether column sources that use this manager should allow reinterpret.

Returns:

If ColumnSource.reinterpret(Class) is allowed

noteUsingComponentsIsUnsafe

public void noteUsingComponentsIsUnsafe()

Note that this UnionSourceManager might have tables added dynamically throughout its lifetime.

isUsingComponentsSafe

public boolean isUsingComponentsSafe()

Determine whether using the component tables directly in a subsequent merge will affect the correctness of the merge.

Returns:

If using the component tables is allowed.

addTable

public void addTable(@NotNull Table table, boolean onNewTableMapKey)

Adds a table to the managed constituents.

Parameters:

table - the new table

onNewTableMapKey - whether this table is being added after the initial setup

getColumnSources

public Map<String,UnionColumnSource> getColumnSources()

getComponentTables

public Collection<Table> getComponentTables()

getResult

@NotNull public QueryTable getResult()
