Field Summary

protected org.slf4j.Logger	logger The internal type, which means special processing of the input/output value.
private SqlMetaType	metaType The internal META type, which means special processing of the input/output value.
private String	value Right now only for the special of the enumeration type of the input value.

Constructor Summary

SqlType()
Creates a new instance with unspecified internal type.

SqlType(SqlMetaType metaType)
Creates a new instance with specified internal type.

Method Summary

(package private) SqlMetaType	getMetaType(SqlProcessContext ctx) Returns the internal type.
String	getValue() Returns the value.
(package private) void	setParameter(SqlProcessContext ctx, SqlQuery query, String paramName, Object inputValue, Class<?> inputType) Bind an input value to a named query parameter.
(package private) void	setResult(SqlProcessContext ctx, Object resultInstance, String attributeName, Object resultValue) Initializes the attribute of the result class with output values from SQL query execution.
void	setValue(String value) Sets the value.

Field Detail

logger

protected final org.slf4j.Logger logger

The internal type, which means special processing of the input/output value.

metaType

private SqlMetaType metaType

The internal META type, which means special processing of the input/output value.

value

private String value

Right now only for the special of the enumeration type of the input value. The logical evaluation of the input value is based on the comparison to this value.

Constructor Detail

SqlType

SqlType()

Creates a new instance with unspecified internal type.

SqlType

SqlType(SqlMetaType metaType)

Creates a new instance with specified internal type.

Parameters:

metaType - the internal type

Method Detail

getMetaType

SqlMetaType getMetaType(SqlProcessContext ctx)

Returns the internal type.

Parameters:

ctx - the crate for all input parameters and the context of processing

Returns:

the internal type

setResult

void setResult(SqlProcessContext ctx,
               Object resultInstance,
               String attributeName,
               Object resultValue)
         throws SqlRuntimeException

Initializes the attribute of the result class with output values from SQL query execution.

Parameters:

ctx - the crate for all input parameters and the context of processing

resultInstance - the instance of the result class

attributeName - the name of the attribute in the result class

resultValue - Query execution output value

Throws:

SqlRuntimeException - in the case of any problem with output values handling

setParameter

void setParameter(SqlProcessContext ctx,
                  SqlQuery query,
                  String paramName,
                  Object inputValue,
                  Class<?> inputType)
            throws SqlRuntimeException

Bind an input value to a named query parameter.

Parameters:

ctx - the crate for all input parameters and the context of processing

query - the SQL Engine query, an adapter or proxy to the internal JDBC or ORM staff

paramName - the name of the parameter

inputValue - the possibly-null parameter value, a dynamic input value

Throws:

SqlRuntimeException - in the case of any problem with input values handling

getValue

public String getValue()

Returns the value. Right now only for the special of the enumeration type of the input value. The logical evaluation of the input value is based on the comparison to this value.

Returns:

the value for special enumeration treatment

setValue

public void setValue(String value)

Sets the value. Right now only for the special of the enumeration type of the input value. The logical evaluation of the input value is based on the comparison to this value.

Parameters:

value - the value for special enumeration treatment

toString

public String toString()

For debug purposes.

Overrides:

toString in class Object

Returns:

a String representation for a debug output
