Constructor Detail

BaseAttributeDefinition

public BaseAttributeDefinition(java.lang.String id,
                               StructureDefinition parent,
                               java.lang.String javaType,
                               boolean isReadOnly,
                               boolean isKey)

Constructor.

Parameters:

id - Identifier, or name, of the attribute.

parent - Metadata of the parent structure.

javaType - Fully-qualified Java class name of the attribute type.

isReadOnly - Whether the attribute is read-only.

isKey - Whether the attribute is the primary key of a row.

Method Detail

isReadOnly

public boolean isReadOnly()

Finds out whether this attribute is read-only or is updateable.

Specified by:

isReadOnly in interface AttributeDefinition

Returns:

True if this attribute is read-only, false otherwise.

setReadOnly

public void setReadOnly(boolean isReadOnly)

Specify whether this attribute is read-only or is updateable.

setSourceTypeString

public void setSourceTypeString(java.lang.String sourceTypeString)

Set the java type of this attribute in the data source.

Parameters:

sourceTypeString - A String representing the java type.

isKey

public boolean isKey()

Finds out whether this attribute is the primary key of the row.

Specified by:

isKey in interface AttributeDefinition

Returns:

True if this attribute is the primary key, false otherwise.

getSourceTypeString

public java.lang.String getSourceTypeString()

Returns the actual java type of the attribute in the data source. This may be different from the java type returned by getJavaTypeString if the data control is returning an attribute as a different datatype as what it is in its data source. For example, if the source type is a java.lang.String representing some number, the java type of the attribute could be java.lang.Integer.

Specified by:

getSourceTypeString in interface AttributeDefinition

Returns:

The java type of the attribute in the data source.

getProperty

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

Retrieves the value of the given property. This class does not provide any properties.

Specified by:

getProperty in interface NamedDefinition

Overrides:

getProperty in class BaseValueObjectDefinition

Parameters:

propertyName - Name of property whose value should be returned.

Returns:

Value of the property whose name is given.

getDefinitionType

public int getDefinitionType()

Description copied from interface: Definition

Retrieves the type of this definition. It can be one of the TYPE_* constants defined in this class. This is useful to find out the actual type of the Definition without doing an instanceof operations.

Specified by:

getDefinitionType in interface Definition

Overrides:

getDefinitionType in class BaseValueObjectDefinition

Returns:

Always return TYPE_PRIMITIVE.
