Method Detail

getResolvedFunction

public ContextResolvedFunction getResolvedFunction()

getArguments

public List<org.apache.flink.table.expressions.ResolvedExpression> getArguments()

getResolvedSchema

public org.apache.flink.table.catalog.ResolvedSchema getResolvedSchema()

Description copied from interface: QueryOperation

Resolved schema of this operation.

Specified by:

getResolvedSchema in interface QueryOperation

asSummaryString

public String asSummaryString()

Description copied from interface: Operation

Returns a string that summarizes this operation for printing to a console. An implementation might skip very specific properties.

Specified by:

asSummaryString in interface Operation

Returns:

summary string of this operation for debugging purposes

asSerializableString

public String asSerializableString(org.apache.flink.table.expressions.SqlFactory sqlFactory)

Description copied from interface: QueryOperation

Returns a SQL string that fully serializes this instance. The serialized string can be used for storing the query in e.g. a Catalog as a view.

Specified by:

asSerializableString in interface QueryOperation

Parameters:

sqlFactory - can be used to customize the serialization to a SQL string

Returns:

Flink SQL string for persisting in a catalog

Specified by:

getChildren in interface QueryOperation

accept

public <U> U accept(QueryOperationVisitor<U> visitor)
