Method Detail

compareTo

public int compareTo(Entity other)
              throws IllegalArgumentException

Specified by:

compareTo in interface Comparable<Entity>

Overrides:

compareTo in class AbstractMetaChildEntity<String,DatabaseModel>

Throws:

IllegalArgumentException

determineReferences

public List<ColumnDefinition> determineReferences()

getDecimals

public final int getDecimals()

getDefaultValue

public final String getDefaultValue()

getLogicalName

public final String getLogicalName()

Specified by:

getLogicalName in interface MetaEntity<String>

Overrides:

getLogicalName in class AbstractMetaEntity<String>

Returns:

the logicalName

getMappings

public Map<String,String> getMappings()

Description copied from interface: Entity

returns a map with mappings of logical property names to physical property names (column names in database terms).

Every implementation should respect the parents mappings. The following sample shows different mapping types:

 public Map<String, String> getMappings() {
     Map<String, String> mappings = super.getMappings();
     mappings.put("title", "name");
     mappings.put("streams", Stream.class.getName());
     mappings.put("pageDefinitions", "pageType|" + ThemeElement.class.getName());
     return mappings;
 }
 

The mappings explained:

"title" -> "name"

the logical "title"-attribute is stored to persistence with a physical name "name"

"streams" -> Stream.class.getName()

the "streams" property holds related children. Unknown children are hold in a List, known (named) children are hold in a Map. The mapped value is used as classname to create child instances.

"pageDefinitions" -> "pageType|" + ThemeElement.class.getName()

pageDefinitions is a property of type Map, that holds grouped children. Known children are hold by a Map, unknown children by a List, so "pageDefinitions" may contain elements of type Map, or List. pageType, a property of ThemeElement, is used to group the children. The word before the '|' is the property name used as key value for grouping and the type after '|' is used to create instances.

Specified by:

getMappings in interface Entity

Overrides:

getMappings in class AbstractMetaEntity<String>

Returns:

a Map with property names as keys and column names as values.

getParentType

public Class<DatabaseModel> getParentType()

Description copied from interface: ChildEntity

returns the type of the parent entity

Returns:

the parent entity

getPersistenceName

public String getPersistenceName()

Description copied from interface: Entity

returns the name of the entity for persistance. Normally it would be the same result as getClass().getSimpleName(), but some storage may have size limitations, or don't support case sensitive names, so this call is to deal with that kind of limitations.

Specified by:

getPersistenceName in interface Entity

Overrides:

getPersistenceName in class AbstractEntity

Returns:

the entity-name used for persistence

getSize

public final int getSize()

getType

public final ColumnType getType()

isAutoincrement

public final boolean isAutoincrement()

needsUpdate

public boolean needsUpdate(AttributeDomain other)

setAutoincrement

public final void setAutoincrement(boolean autoincrement)

setDecimals

public final void setDecimals(int decimals)

setDefaultValue

public final void setDefaultValue(String defaultValue)

setLogicalName

public final void setLogicalName(String logicalName)

Parameters:

logicalName - the logicalName to set

setSize

public final void setSize(int size)

setType

public final void setType(ColumnType type)

toString

public String toString()

Overrides:

toString in class AbstractEntity
