Field Summary

private javax.swing.tree.DefaultMutableTreeNode	_attNode The representation of this attribute as a DefaultMutableTreeNode
private DataType	_dataType The data type of the attribute
private java.lang.String	_name The name of the attribute
private java.lang.String	_tempDataType The temporary data type

Constructor Summary

EntityAttribute(java.lang.String inName, DataType inDataType)
Default Constructor

EntityAttribute(java.lang.String inName, java.lang.String inType)
Constructor for reading in from file when the data types have not yet been initiated and thus we must load their references after loading them into the data type controller

Method Summary

DataType	getDataType() Returns data type
java.lang.String	getName() Returns name of attribute.
javax.swing.tree.DefaultMutableTreeNode	getNode() Returns the node used for displaying the attribute
static boolean	isAttNameUsed(EntityNode inNode, java.lang.String attName) Check to see if an attribute name is already used in the entity
static boolean	isProtectedName(EntityNode parent, java.lang.String attName) Determines whether an attribute name is protected.
void	setDataType(DataType inType) Sets the data type of the attribute
void	setName(java.lang.String inName) Sets the attribute name.
void	setNode(javax.swing.tree.DefaultMutableTreeNode inNode) Sets the node used for displaying the attribute
void	setTypeFromTemp() Sets the data type from the temporary type name
java.lang.String	toString() Overwrite standard toString function.

Constructor Detail

EntityAttribute

public EntityAttribute(java.lang.String inName,
                       DataType inDataType)

Default Constructor

EntityAttribute

public EntityAttribute(java.lang.String inName,
                       java.lang.String inType)

Constructor for reading in from file when the data types have not yet been initiated and thus we must load their references after loading them into the data type controller

Parameters:

inName - The name of the attribute

inType - The name of the data type used for the attribute

Method Detail

toString

public java.lang.String toString()

Overwrite standard toString function. (provides functionality for inserting attributes to the tree)

Overrides:

toString in class java.lang.Object

Returns:

The name of this attribute formatted for display on the tree

setName

public void setName(java.lang.String inName)

Sets the attribute name.

Parameters:

inName - Attribute Name

getName

public java.lang.String getName()

Returns name of attribute.

Returns:

Name of attribute.

getDataType

public DataType getDataType()

Returns data type

Returns:

Data type

setTypeFromTemp

public void setTypeFromTemp()

Sets the data type from the temporary type name

setDataType

public void setDataType(DataType inType)

Sets the data type of the attribute

Parameters:

inType - The data type of the attribute

setNode

public void setNode(javax.swing.tree.DefaultMutableTreeNode inNode)

Sets the node used for displaying the attribute

Parameters:

inNode - The node used for displaying the attribute

getNode

public javax.swing.tree.DefaultMutableTreeNode getNode()

Returns the node used for displaying the attribute

Returns:

The node used for displaying the attribute

isAttNameUsed

public static boolean isAttNameUsed(EntityNode inNode,
                                    java.lang.String attName)

Check to see if an attribute name is already used in the entity

Parameters:

inNode - The entity being checked against

attName - The name being checked for duplication

Returns:

true if the name is in use, false otherwise

isProtectedName

public static boolean isProtectedName(EntityNode parent,
                                      java.lang.String attName)

Determines whether an attribute name is protected. Attribute names that commence with the name of the entity followed by the SQL identifier are protected
