Method Details

flatten(self)

source code

returns a string representation of the text content of the tree.

This default implementation will only work if you returned all parsed elements as children. This, in turn, is something you only want to do if you are sure that the node is question will not be morphed.

Otherwise, override it to create an SQL fragment out of the parsed attributes.

Overrides: ADQLNode.flatten: (inherited documentation)

getAllFields(self)

source code

returns all fields from all tables in this FROM.

These will be qualified names. Columns taking part in joins are resolved here.

This will only work for annotated tables.

getFieldsForTable(self, srcTableName)

source code

returns the fields in srcTable.

srcTableName is a TableName.

init(self, tableReference=`()`, tables=`()`)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__: (inherited documentation)
