protected QualifiedDBIdentifier(DBIdentifier... sNames)

Method Detail

newPath

public static QualifiedDBIdentifier newPath(DBIdentifier... names)

Creates a qualified identifier based upon an array of DBIdentifiers. Identifiers must be specified in order.

Parameters:

names -

setPath

public void setPath(DBIdentifier... sNames)

Set the identifiers that make up the path. Identifiers must be specified in path order. (ex. [ table, column ] )

Parameters:

sNames -

splitPath

public static DBIdentifier[] splitPath(DBIdentifier sName)

Splits a qualified path into separate identifiers.

Parameters:

sName -

getPath

public static QualifiedDBIdentifier getPath(DBIdentifier sName)

Creates a qualified path from an identifier.

Parameters:

sName -

setSchemaName

public void setSchemaName(DBIdentifier schemaName)

Sets the schema component of the path.

getSchemaName

public DBIdentifier getSchemaName()

Gets the schema component of the path.

setObjectTableName

public void setObjectTableName(DBIdentifier objectName)

Sets the object table name component of the path, if the path is a table qualified identifier such as a constraint or column.

getObjectTableName

public DBIdentifier getObjectTableName()

Gets the object table name component of the path, if the path is a table qualified identifier such as a constraint or column.

isUnqualifiedObject

public boolean isUnqualifiedObject()

Returns true if this object is not qualified by a schema component.

isUnqualifiedColumn

public boolean isUnqualifiedColumn()

Returns true if this object is not qualified by a table or schema component.

equals

public boolean equals(Object obj)

Equality operator.

Overrides:

equals in class DBIdentifier

pathEqual

public static boolean pathEqual(QualifiedDBIdentifier path1,
                QualifiedDBIdentifier path2)

Compares two qualified identifiers for equality.

Parameters:

path1 -

path2 -

toString

public String toString()

Returns a fully qualified name as a string.

Overrides:

toString in class IdentifierImpl

getName

public String getName()

Returns the fully qualified name as a string

Specified by:

getName in interface Identifier

Overrides:

getName in class IdentifierImpl

getBaseName

public String getBaseName()

Returns the base name of this qualified name. For example, if the qualified name is a schema qualified table, the table name is returned.

getIdentifier

public DBIdentifier getIdentifier()

Returns this object as a DBIdentifier.

setName

public void setName(String name)

Set the name of this qualified identifier. Splits the string into multiple components. This method assumes the type does not change.

Specified by:

setName in interface Identifier

Overrides:

setName in class DBIdentifier

setBaseName

protected void setBaseName(String name)
