Method Detail

applySelectFunction
String applySelectFunction(String replacementValue)(Code)
	Wraps the column name with a FUNCTION. example: SQRT(?) generates: SQRT(columnName) Parameters: replacementValue - the replacement to ?. Probably it's a column name, that may be fully qualified name or not a String with function taking as parameter the replacementValue

copyConfigurationTo
void copyConfigurationTo(DatastoreField col)(Code)
	Copy the configuration of this field to another field Parameters: col - the datastore field

getDatastoreContainerObject
DatastoreContainerObject getDatastoreContainerObject()(Code)
	Accessor for the DatastoreContainerObject container of this field The DatastoreContainerObject

getDatastoreMapping
DatastoreMapping getDatastoreMapping()(Code)
	Accessor for the datastore mapping that this datastore field relates to. The datastore mapping

getFieldMetaData
AbstractMemberMetaData getFieldMetaData()(Code)
	Accessor for the MetaData of the field that this is the datastore field for. MetaData of the field (if representing a field of a class).

getMapping
JavaTypeMapping getMapping()(Code)
	Accessor for the Mapping for this field. TODO Change this to DatastoreMapping since a DatastoreField maps via that and not JavaTypeMapping. The Mapping

getMetaData
MetaData getMetaData()(Code)
	Access the metadata definition defining this DatastoreField. the MetaData

getStoredJavaType
String getStoredJavaType()(Code)
	Accessor for the type of data stored in this field. The type of data in the field.

isNullable
boolean isNullable()(Code)
	Accessor for whether the field is nullable in the datastore. whether the field is nullable

isPrimaryKey
boolean isPrimaryKey()(Code)
	Accessor for whether the field is the primary key in the datastore. whether the field is (part of) the primary key

setAsPrimaryKey
void setAsPrimaryKey()(Code)
	Mutator to make the field the primary key.

setDatastoreMapping
void setDatastoreMapping(DatastoreMapping mapping)(Code)
	Method to associate this datastore field with its mapping. Parameters: mapping - The mapping for this datastore field

setDefaultable
DatastoreField setDefaultable()(Code)
	Mutator for the defaultability of the datastore field. The datastore field with the updated info

setIdentifier
void setIdentifier(DatastoreIdentifier identifier)(Code)
	Mutator for the identifier of the column. Parameters: identifier - The identifier

setMetaData
void setMetaData(MetaData md)(Code)
	Method to set the MetaData for this datastore field. Should only be called before completion of initialisation. Parameters: md - The MetaData

setNullable
DatastoreField setNullable()(Code)
	Mutator for the nullability of the datastore field. The datastore field with the updated info
