Method Detail

getAttributeKind

public byte getAttributeKind()

Description copied from interface: AttributeDef

Gets the attribute value.

Specified by:

getAttributeKind in interface AttributeDef

Returns:

one of the ATTR constants defined for this class.

getName

public java.lang.String getName()

Description copied from interface: AttributeDef

Gets the name of the attribute.

Specified by:

getName in interface AttributeDef

Returns:

the name of the attribute.

getColumnName

public java.lang.String getColumnName()

Description copied from interface: AttributeDef

Gets the name of the database column the attribute represents.

Specified by:

getColumnName in interface AttributeDef

Returns:

the name of the column.

getColumnNameForQuery

public java.lang.String getColumnNameForQuery()

Description copied from interface: AttributeDef

Gets the column name to be used in query statement. If the VO involves multiple entity usages, the column name may have to be qualified with the table alias for the appropriate entity. If the query statement is a full query ("expert mode"), the where-clause in the outer select must use column alias used for the inner select. This method takes care of all this and returns the right column name to be used for a query statement.

Specified by:

getColumnNameForQuery in interface AttributeDef

Returns:

the column name to be used in query.

getIndex

public int getIndex()

Description copied from interface: AttributeDef

Gets the index of the attribute in the context of a StoreInfo instance.

Specified by:

getIndex in interface AttributeDef

Returns:

the index of the attribute row's definition object.

getJavaType

public java.lang.Class getJavaType()

Description copied from interface: AttributeDef

Gets the Java class of the object stored for this attribute definition.

Specified by:

getJavaType in interface AttributeDef

Returns:

the class of the attribute.

getSQLType

public int getSQLType()

Description copied from interface: AttributeDef

Gets the JDBC type of the attribute.

Specified by:

getSQLType in interface AttributeDef

Returns:

the JDBC type.

Types

getScale

public int getScale()

Description copied from interface: AttributeDef

Get the scale value of a numeric attribute.

Specified by:

getScale in interface AttributeDef

Returns:

the scale value for this attribute, if applicable.

getPrecision

public int getPrecision()

Description copied from interface: AttributeDef

Gets the precision of a numeric or string attribute.

'Precision' for a string is the maximum length.

Specified by:

getPrecision in interface AttributeDef

Returns:

the precision value for this attribute.

isQueriable

public boolean isQueriable()

Description copied from interface: AttributeDef

Tests if an attribute is queriable.

Queriable is a UI/Control-Hint that the JSP and other form-generation utilities use to generate the find form. In JClient this flag is consulted at runtime to decide if an attribute-bound control should participate in find mode to build where-clause-fragments for a ViewObject.

Specified by:

isQueriable in interface AttributeDef

Returns:

true if this attribute is queriable.

getUpdateableFlag

public byte getUpdateableFlag()

Description copied from interface: AttributeDef

Tests if an attribute can be modified.

Specified by:

getUpdateableFlag in interface AttributeDef

Returns:

READONLY, UPDATEABLE, or UPDATEABLE_WHILE_NEW.

isPrimaryKey

public boolean isPrimaryKey()

Description copied from interface: AttributeDef

Tests if an attribute is a Primary Key.

Specified by:

isPrimaryKey in interface AttributeDef

Returns:

true if this is either a Primary Key attribute or part of the attributes that constitute the Primary Key for a given row.

isMandatory

public boolean isMandatory()

Description copied from interface: AttributeDef

Tests if an attribute does not allow null values.

Specified by:

isMandatory in interface AttributeDef

Returns:

true if this attribute cannot store a null value

getUIHelper

public AttributeHints getUIHelper()

Description copied from interface: AttributeDef

Returns the user interface hints interface for retrieving hint information such as labels, prompts,...

Specified by:

getUIHelper in interface AttributeDef

See Also:

AttributeHints

getElemType

public java.lang.Class getElemType()

Description copied from interface: AttributeDef

Returns the element type of the attribute.

For VARRAYs, this method returns the class name of the elements that are in the VARRAY.

Element type is relevant only if the attribute is an array attribute.

Specified by:

getElemType in interface AttributeDef

Returns:

the attribute's element class, or null if the attribute is not an array attribute.

getElemSQLType

public int getElemSQLType()

Description copied from interface: AttributeDef

Returns the jdbc type of the elements of this attribute.

For VARRAYs, this method returns the jdbc type of the elements that are in the VARRAY.

Element type is relevant only if the attribute is an array attribute.

Specified by:

getElemSQLType in interface AttributeDef

Returns:

the jdbc type (java.sql.Types.*) of this attribute's elements, or java.sql.Types.NULL if this attribute is not an array attribute.

getProperty

public java.lang.Object getProperty(java.lang.String hintName)

Description copied from interface: Properties

Retrieves the specified property, if it exists.

Specified by:

getProperty in interface Properties

hintName - Property name.

Returns:

the value of the property, if any, otherwise null.

refreshProperty

public java.lang.Object refreshProperty(java.lang.String hintName)

Description copied from interface: Properties

Retrieves the specified property, if it exists. If the application running in a 3 tier environment, it retrieves the property from the middle-tier server, refreshing the value on the client side. If the application is running in a 2 tier environment, it is equivalent to getProperty.

Specified by:

Parameters:

hintName - Property name.

Returns:

the value of the property, if any, otherwise null.

getProperties

public java.util.Hashtable getProperties()

Description copied from interface: Properties

Gets the table of properties.
