                          DataTypeAttribute[] attributes)

Use this constructor when the datatype is not just a simple name, but has declarable attributes, e.g. Oracle TIMESTAMP[(<scale>)][ WITH <zone>].

Parameters:

Description copied from interface: DataType

Returns an DataTypeUsage object for this type, populated with attributes. Should be overridden by sub-classes to return an object of the sub-class type.

Specified by:

createUsage in interface DataType

validateUsage

public void validateUsage(DataTypeUsage dataTypeUsage,
                          DBObject dbObject)
                   throws DataTypeValidationException

Description copied from interface: DataType

Validates dataTypeUsage against self's definition. Uses dataTypeUSage's get() methods to get the actual property values for validation. Should be overridden by sub-classes to do sub-class validation.

Specified by:

validateUsage in interface DataType

Parameters:

dataTypeUsage - : the usage to be validated

dbObject - : the context of the data type usage

Throws:

DataTypeValidationException

validateDefaultValue

public void validateDefaultValue(java.lang.Object defaultValue,
                                 DataTypeUsage dataTypeUsage,
                                 DBObject dbObject)
                          throws DefaultValueValidationException

Description copied from interface: DataType

Validates defaultValue for dataTypeUsage against self's definition. Method should be overridden by sub-classes to do sub-class validation.

Specified by:

validateDefaultValue in interface DataType

Parameters:

defaultValue - : the default value

dataTypeUsage - : the usage to be validated

dbObject - : the context of the data type usage

Throws:

DefaultValueValidationException

getDDL

public java.lang.String getDDL(DataTypeUsage dataTypeUsage)

Description copied from interface: DataType

Generates the DDL for this type. Uses dataTypeUsages's get() methods to get the actual property values. Should be overridden by sub-classes to generate extra bits.

Specified by:

getDDL in interface DataType

hasDataTypeAttribute

public final boolean hasDataTypeAttribute(java.lang.String name)

Returns true if the DataTypeAttribute name is on this DataType.

Specified by:

hasDataTypeAttribute in interface DataType

Returns:

true if the DataTypeAttribute corresponding to name exists.

getDataTypeAttribute

public final DataTypeAttribute getDataTypeAttribute(java.lang.String name)

Returns the DataTypeAttribute called name or null if this data type doesn't define it.

Specified by:

getDataTypeAttribute in interface DataType

Parameters:

name - the name of the attribute to find

Returns:

The DataTypeAttribute corresponding to name or null if none exists.

getDataTypeAttributes

public final DataTypeAttribute[] getDataTypeAttributes()

Specified by:

getDataTypeAttributes in interface DataType

Returns:

DataType's DataTypeAttributes in the order they were added.

setDataTypeAttributes

public final void setDataTypeAttributes(DataTypeAttribute[] attrs)

getParent

public final DBObject getParent()

Description copied from interface: DBObject

Returns the parent of this object, if one exists. This does not return the Schema for a SchemaObject. Schema's are not considered part of the ownership parent tree.

Specified by:

getParent in interface DBObject

getType

public final java.lang.String getType()

Description copied from interface: DBObject

Returns the type of this object. Valid types include things like tables, views, synonyms, and columns.

Specified by:

                          IDPolicy idPolicy)

Description copied from class: AbstractDBObject

Implementation method for making a copy of this object. To add custom copyTo logic, a subclass must override this method (exactly), and must call back to the super implementation.

Overrides:

copyToImpl in class AbstractDBObject

Parameters:

other - the copy being created of this object

copyParent - if this object is being copied underneath a parent, this parameter is the copy of the parent of this object, which will therefore need to be the parent of the copy of this object.

idPolicy - the policy for copying the object's ID.

equalsImpl

protected boolean equalsImpl(AbstractDBObject target)

Description copied from class: AbstractDBObject

Equals implementation for testing equality with another AbstractDBObject. Override this method (with exact signature) to customise the equality comparison.

Overrides:

equalsImpl in class AbstractDBObject

validateDefinition

public void validateDefinition()
                        throws DataTypeValidationException

Throws:

DataTypeValidationException

tokenize

protected static java.lang.String[] tokenize(java.lang.String string,
                                             java.lang.String delimiters)

Creates a String[] of tokens extracted from string. The String[] that is returned contains the tokens and delimiters, except for spaces.

parseDefaultValue

protected static PlsqlNode parseDefaultValue(java.lang.String strDefaultValue,
                                             DataType dataType,

                                      throws DefaultValueValidationException

Parse the default value. Return the Node at the top of the parse tree, or null if the parser result is not understood.

Throws:

DefaultValueValidationException - if there are parser exceptions

matches

public boolean matches(java.lang.String usageString)

Description copied from interface: DataType

Returns true if the usageString is valid syntax for the DataType, false otherwise. Should be overridden by sub-classes to do the validation.

Specified by:

matches in interface DataType

createUsage

public DataTypeUsage createUsage(java.lang.String usageString)

Description copied from interface: DataType

Returns an DataTypeUsage object for this type, populated with attributes based on the usageString. Returns null if the usageString does not match the syntax of the DataType. See DataType.matches(java.lang.String). Should be overridden by sub-classes to return an object of the sub-class type.
