Field Detail

• protected java.util.Set<java.lang.String> associationNames

• protected org.grails.datastore.mapping.model.PersistentEntity entity

• protected java.lang.String propertyName

Constructor Detail

• public EntityFetchOptions(java.lang.Class<?> entityClass)

• public EntityFetchOptions(java.lang.Class<?> entityClass, java.lang.String projectionName)

• public EntityFetchOptions(org.grails.datastore.mapping.model.PersistentEntity entity)

• public EntityFetchOptions(org.grails.datastore.mapping.model.PersistentEntity entity, java.lang.String projectionName)

  Designed for use when a projection query is used. The fetch arguments need prepended with the projection property name.

  Parameters:

  entity - The org.grails.datastore.mapping.model.PersistentEntity being queried

  projectionName - The name of the property being projected

Method Detail

• public java.util.Map<java.lang.String, org.grails.datastore.mapping.model.types.Association> getAssociations()

  Returns:

  The associations of the org.grails.datastore.mapping.model.PersistentEntity. The key is the property name and the value is the association.

• public java.util.Map<java.lang.String, java.util.Map> getFetchArgument(java.util.Set<java.lang.String> properties)

  Creates the fetch argument prepared to pass to grails.gorm.DetachedCriteria#list(Map)

  Parameters:

  properties - The properties to fetch

  Returns:

  The fetch argument

• public java.util.Map<java.lang.String, java.util.Map> getFetchArgument(graphql.schema.DataFetchingEnvironment environment)

• public java.util.Map<java.lang.String, java.util.Map> getFetchArgument(graphql.schema.DataFetchingEnvironment environment, boolean skipCollections)

  Inspects the environment for requested fields and compares against the org.grails.datastore.mapping.model.PersistentEntity associations to determine which fields should be eagerly fetched. Creates the fetch argument prepared to pass to grails.gorm.DetachedCriteria#list(Map)

  Parameters:

  environment - The fetching environment

  skipCollections - Whether to exclude associations that are collections

  Returns:

  The fetch argument

• public java.util.Set<java.lang.String> getJoinProperties(java.util.List<graphql.language.Field> fields)

• public java.util.Set<java.lang.String> getJoinProperties(java.util.List<graphql.language.Field> fields, boolean skipCollections)

  Designed for internal use to inspect nested selections

  Parameters:

  fields - The list of fields to search

  skipCollections - Whether to exclude associations that are collections

  Returns:

  The list of properties to eagerly fetch

• public java.util.Set<java.lang.String> getJoinProperties(graphql.schema.DataFetchingEnvironment environment)

• public java.util.Set<java.lang.String> getJoinProperties(graphql.schema.DataFetchingEnvironment environment, boolean skipCollections)

  Inspects the environment for requested fields and compares against the org.grails.datastore.mapping.model.PersistentEntity associations to determine which fields should be eagerly fetched.

  Parameters:

  environment - The data fetching environment

  skipCollections - Whether to exclude associations that are collections

  Returns:

  The list of properties to eagerly fetch

• protected void handleField(java.lang.String parentName, Field selectedField, java.util.Set<java.lang.String> joinProperties)

• protected boolean isForeignKeyInChild(org.grails.datastore.mapping.model.types.Association association)
