canDoExtraction

boolean canDoExtraction()

Can the given instance of this type actually perform the parameter value extractions?

返回:

true indicates that @{link #extract} calls will not fail due to IllegalStateException.

extract

T extract(CallableStatement statement,
          int startIndex,
          SharedSessionContractImplementor session)
   throws SQLException

Perform the extraction

参数:

statement - The CallableStatement from which to extract the parameter value(s).

startIndex - The parameter index from which to start extracting; assumes the values (if multiple) are contiguous

session - The originating session

返回:

The extracted value.

抛出:

SQLException - Indicates an issue calling into the CallableStatement

IllegalStateException - Thrown if this method is called on instances that return false for canDoExtraction()

extract

T extract(CallableStatement statement,
          String[] paramNames,
          SharedSessionContractImplementor session)
   throws SQLException

Perform the extraction

参数:

statement - The CallableStatement from which to extract the parameter value(s).

paramNames - The parameter names.

session - The originating session

返回:

The extracted value.

抛出:

SQLException - Indicates an issue calling into the CallableStatement

IllegalStateException - Thrown if this method is called on instances that return false for canDoExtraction()
