Class EventMigrationPropertyBuilderFor<TTarget, TSource>

Namespace: Cratis.Chronicle.Events.Migrations

Assembly: Cratis.Chronicle.dll

Represents an implementation of IEventMigrationPropertyBuilder<TTarget, TSource> that converts expression-based property accessors to PropertyName values and delegates to the underlying IEventMigrationPropertyBuilder.

public class EventMigrationPropertyBuilderFor<TTarget, TSource> : IEventMigrationPropertyBuilder<TTarget, TSource>

Type Parameters

TTarget: The target event type of the migration.
TSource: The source event type of the migration.

Constructors

EventMigrationPropertyBuilderFor(IEventMigrationPropertyBuilder)

public EventMigrationPropertyBuilderFor(IEventMigrationPropertyBuilder inner)

Parameters

inner IEventMigrationPropertyBuilder: The underlying IEventMigrationPropertyBuilder to delegate to.

Methods

Combine<TProperty>(Expression<Func<TTarget, TProperty>>, PropertySeparator, params Expression<Func<TSource, object>>[])

Combine multiple source properties into a single target property by concatenation.

public IEventMigrationPropertyBuilder<TTarget, TSource> Combine<TProperty>(Expression<Func<TTarget, TProperty>> targetProperty, PropertySeparator separator, params Expression<Func<TSource, object>>[] sourceProperties)

Parameters

targetProperty Expression<Func<TTarget, TProperty>>: Expression selecting the target property to write the combined result into.
separator PropertySeparator: The separator to use between the combined values.
sourceProperties Expression<Func<TSource, object>>[]: Expressions selecting the source properties to concatenate.

Returns

IEventMigrationPropertyBuilder<TTarget, TSource>: The builder for continued configuration.

Type Parameters

TProperty: The type of the target property.

DefaultValue<TProperty>(Expression<Func<TTarget, TProperty>>, TProperty)

Provide a default value for a new property that did not exist in the source generation.

public IEventMigrationPropertyBuilder<TTarget, TSource> DefaultValue<TProperty>(Expression<Func<TTarget, TProperty>> targetProperty, TProperty value)

Parameters

targetProperty Expression<Func<TTarget, TProperty>>: Expression selecting the target property to set the default value on.
value TProperty: The default value.

Returns

IEventMigrationPropertyBuilder<TTarget, TSource>: The builder for continued configuration.

Type Parameters

TProperty: The type of the target property.

MapValues<TProperty, TSourceProperty>(Expression<Func<TTarget, TProperty>>, Expression<Func<TSource, TSourceProperty>>, Action<IValueMapBuilder<TSourceProperty, TProperty>>)

Translate the individual values of a property that mean something different in the target generation.

public IEventMigrationPropertyBuilder<TTarget, TSource> MapValues<TProperty, TSourceProperty>(Expression<Func<TTarget, TProperty>> targetProperty, Expression<Func<TSource, TSourceProperty>> sourceProperty, Action<IValueMapBuilder<TSourceProperty, TProperty>> map)

Parameters

targetProperty Expression<Func<TTarget, TProperty>>: Expression selecting the target property to write the translated value into.
sourceProperty Expression<Func<TSource, TSourceProperty>>: Expression selecting the source property to read the value from.
map Action<IValueMapBuilder<TSourceProperty, TProperty>>: Action declaring which value becomes which.

Returns

IEventMigrationPropertyBuilder<TTarget, TSource>: The builder for continued configuration.

Type Parameters

TProperty: The type of the target property.
TSourceProperty: The type of the source property.

Remarks

This states the translation for one direction only. To state it once and have both directions follow, override MapValues on EventTypeMigration<TUpgrade, TPrevious> instead.

RenamedFrom<TProperty>(Expression<Func<TTarget, TProperty>>, Expression<Func<TSource, object>>)

Rename a property from an old name to a new target property.

public IEventMigrationPropertyBuilder<TTarget, TSource> RenamedFrom<TProperty>(Expression<Func<TTarget, TProperty>> targetProperty, Expression<Func<TSource, object>> sourceProperty)

Parameters

targetProperty Expression<Func<TTarget, TProperty>>: Expression selecting the new target property.
sourceProperty Expression<Func<TSource, object>>: Expression selecting the old source property to read from.

Returns

IEventMigrationPropertyBuilder<TTarget, TSource>: The builder for continued configuration.

Type Parameters

TProperty: The type of the target property.

Split<TProperty>(Expression<Func<TTarget, TProperty>>, Expression<Func<TSource, object>>, PropertySeparator, SplitPartIndex)

Split a source property value into a target property by extracting one part.

public IEventMigrationPropertyBuilder<TTarget, TSource> Split<TProperty>(Expression<Func<TTarget, TProperty>> targetProperty, Expression<Func<TSource, object>> sourceProperty, PropertySeparator separator, SplitPartIndex part)

Parameters

targetProperty Expression<Func<TTarget, TProperty>>: Expression selecting the target property to write the split result into.
sourceProperty Expression<Func<TSource, object>>: Expression selecting the source property to split.
separator PropertySeparator: The separator to use.
part SplitPartIndex: The zero-based part index to extract.

Returns

IEventMigrationPropertyBuilder<TTarget, TSource>: The builder for continued configuration.

Type Parameters

TProperty: The type of the target property.
