Constructor Detail

Identifier

public Identifier(String text,
                  boolean quoted)

Constructs an identifier instance.

Parameters:

text - The identifier text.

quoted - Is this a quoted identifier?

Method Detail

toIdentifier

public static Identifier toIdentifier(String text)

Means to generate an Identifier instance from its simple text form.

If passed text is null, null is returned.

If passed text is surrounded in quote markers, the generated Identifier is considered quoted. Quote markers include back-ticks (`), and double-quotes (").

Parameters:

text - The text form

Returns:

The identifier form, or null if text was null

toIdentifier

public static Identifier toIdentifier(String text,
                                      boolean quote)

Means to generate an Identifier instance from its simple text form.

If passed text is null, null is returned.

If passed text is surrounded in quote markers, the generated Identifier is considered quoted. Quote markers include back-ticks (`), and double-quotes (").

Parameters:

text - The text form

quote - Whether to quote unquoted text forms

Returns:

The identifier form, or null if text was null

isQuoted

public static boolean isQuoted(String name)

Is the given identifier text considered quoted. The following patterns are recognized as quoted:

• `name`
• [name]
• "name"

That final form using double-quote (") is the JPA-defined quoting pattern. Although it is the standard, it makes for ugly declarations.

Parameters:

name -

Returns:

getText

public String getText()

Get the identifiers name (text)

Returns:

The name

isQuoted

public boolean isQuoted()

Is this a quoted identifier>

Returns:

True if this is a quote identifier; false otherwise.

render

public String render(Dialect dialect)

If this is a quoted identifier, then return the identifier name enclosed in dialect-specific open- and end-quotes; otherwise, simply return the unquoted identifier.

Parameters:

dialect - The dialect whose dialect-specific quoting should be used.

Returns:

if quoted, identifier name enclosed in dialect-specific open- and end-quotes; otherwise, the unquoted identifier.
