Method Detail

isPrimitiveMappedToNullableColumn

public boolean isPrimitiveMappedToNullableColumn()

isMappedToLob

public boolean isMappedToLob()

Determines if this field is mapped to a LOB column type. It is assumed that lob fields are mapped to only one columns and UI and model verifications enforce it.

Returns:

true if field is mapped to LOB column type. false otherwise.

isCharLobType

public static boolean isCharLobType(int sqlType)

Determines if sqltype passed to this method is to be considered a character LOB type.

Returns:

true if field is mapped to character LOB column type. false otherwise.

isFixedCharType

public static boolean isFixedCharType(int sqlType)

Determines if the sqlType passed to this method corresponds to a fixed char type.

Parameters:

sqlType - The input sqlType.

Returns:

true if field is mapped to Types.CHAR false otherwise.

getPrimaryColumn

public org.netbeans.modules.dbschema.ColumnElement getPrimaryColumn()

Gets the ColumnElement for the primary column of this field.

Returns:

The ColumnElement for the primary column of this field.

getColumnElements

public Iterator getColumnElements()

Returns an iterator on the mapped column elements.

Returns:

An iterator on the mapped column elements.

isVersion

public boolean isVersion()

Returns true if this field is a version field.

incrementValue

public void incrementValue(StateManager sm)

Increments this field in the instance managed by state manager sm by one.

Parameters:

sm - State manager to be modified.

setupDesc

protected void setupDesc(Field f)

Calls the superclass method and disables concurrency checking for certain field types.

Overrides:

setupDesc in class FieldDesc
