Method Detail

normalizeQuoting

public Identifier normalizeQuoting(Identifier identifier)

Description copied from interface: IdentifierHelper

Essentially quotes the identifier if it needs to be. Useful to apply global quoting, as well as reserved word quoting after calls to naming strategies.

Specified by:

normalizeQuoting in interface IdentifierHelper

Parameters:

identifier - The identifier for which to normalize quoting.

Returns:

The quoting-normalized Identifier.

toIdentifier

public Identifier toIdentifier(String text)

Description copied from interface: IdentifierHelper

Generate an Identifier instance from its simple name as obtained from mapping information.

Note that Identifiers returned from here may be implicitly quoted based on 'globally quoted identifiers' or based on reserved words.

Specified by:

toIdentifier in interface IdentifierHelper

Parameters:

text - The text form of a name as obtained from mapping information.

Returns:

The identifier form of the name.

toIdentifier

public Identifier toIdentifier(String text,
                               boolean quoted)

Description copied from interface: IdentifierHelper

Generate an Identifier instance from its simple name as obtained from mapping information. Additionally, this form takes a boolean indicating whether to explicitly quote the Identifier.

Note that Identifiers returned from here may be implicitly quoted based on 'globally quoted identifiers' or based on reserved words.

Specified by:

toIdentifier in interface IdentifierHelper

Parameters:

text - The text form of a name as obtained from mapping information.

quoted - Is the identifier to be quoted explicitly.

Returns:

The identifier form of the name.

applyGlobalQuoting

public Identifier applyGlobalQuoting(String text)

Description copied from interface: IdentifierHelper

Needed to account for certain fields (Column.columnDefinition() comes to mind) that need to be quoted id global identifier quoting is requested, but only for spec compliance. TBH, I can not think of a argument why column-definitions should ever be *globally* quoted, but the spec is the spec.

Specified by:

applyGlobalQuoting in interface IdentifierHelper

Parameters:

text - The text to be (possibly) quoted

Returns:

The identifier form

isReservedWord

public boolean isReservedWord(String word)

Description copied from interface: IdentifierHelper

Check whether the given word represents a reserved word.

Specified by:

isReservedWord in interface IdentifierHelper

Parameters:

word - The word to check

Returns:

true if the given word represents a reserved word; false otherwise.

toMetaDataCatalogName

public String toMetaDataCatalogName(Identifier identifier)

Description copied from interface: IdentifierHelper

Render the Identifier representation of a catalog name into the String form needed in DatabaseMetaData calls.

Specified by:

toMetaDataCatalogName in interface IdentifierHelper

Parameters:

identifier - The Identifier representation of a catalog name

Returns:

The String representation of the given catalog name

toMetaDataSchemaName

public String toMetaDataSchemaName(Identifier identifier)

Description copied from interface: IdentifierHelper

Render the Identifier representation of a schema name into the String form needed in DatabaseMetaData calls.

Specified by:

toMetaDataSchemaName in interface IdentifierHelper

Parameters:

identifier - The Identifier representation of a schema name

Returns:

The String representation of the given schema name

toMetaDataObjectName

public String toMetaDataObjectName(Identifier identifier)

Description copied from interface: IdentifierHelper

Render the Identifier representation of an object name (table, sequence, etc) into the String form needed in DatabaseMetaData calls.

Specified by:

toMetaDataObjectName in interface IdentifierHelper

Parameters:

identifier - The Identifier representation of an object name

Returns:

The String representation of the given object name
