Method Details

getRegistrationKeys

public String[] getRegistrationKeys()

Description copied from interface: Type

Returns the names that this type will be mapped as.

For example, when creating a custom mapping for io.debezium.data.Bits, a type could be registered using the LOGICAL_NAME of the schema if the type is to be used when a schema name is identified; otherwise it could be registered as the raw column type when column type propagation is enabled.

getQueryBinding

public String getQueryBinding(ColumnDescriptor column,
 org.apache.kafka.connect.data.Schema schema,
 Object value)

Description copied from interface: Type

Return the SQL string to be used in DML statements for binding this type to SQL.

Specified by:

getQueryBinding in interface Type

Overrides:

getQueryBinding in class AbstractType

Parameters:

column - column descriptor in the table relational model, never null

schema - field schema, never null

value - value to be bound, may be null

Returns:

query parameter argument binding SQL fragment

getTypeName

public String getTypeName(DatabaseDialect dialect,
 org.apache.kafka.connect.data.Schema schema,
 boolean key)

Description copied from interface: Type

Return the SQL type name for this type.

Parameters:

dialect - dialect instance, never null

schema - field schema, never null

key - whether the type resolution is for a key field

Returns:

the resolved type to be used in DDL statements

bind

public int bind(org.hibernate.query.Query<?> query,
 int index,
 org.apache.kafka.connect.data.Schema schema,
 Object value)

Description copied from interface: Type

Binds the value to the query.

Specified by:

bind in interface Type

Overrides:

bind in class AbstractType

Parameters:

query - hibernate query, is never null

index - parameter index to bind

schema - field schema, never null

value - value to be bound, may be null

Returns:

the number of bound parameters

resolveType

private String resolveType(org.apache.kafka.connect.data.Schema schema)

isJsonb

private boolean isJsonb(org.apache.kafka.connect.data.Schema schema)

isHstore

private boolean isHstore(org.apache.kafka.connect.data.Schema schema)
