Field Detail

metaType

private SqlMetaType metaType

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

hibernateType

private org.hibernate.type.Type hibernateType

The Hibernate type. A standard way to assing the type of parameter/scalar binding to the Hibernate Query.

value

private java.lang.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.

hibernateTypes

static java.util.Map<java.lang.String,java.lang.reflect.Field> hibernateTypes

The map between a String representation of Hibernate types and a Hibernate types.

hibernateTypes2

static java.util.Map<java.lang.Class<?>,org.hibernate.type.Type> hibernateTypes2

The map between an input/output Java types and a Hibernate types.

Constructor Detail

SqlType

SqlType()

Creates a new instance with unspecified internal and Hibernate types.

SqlType

SqlType(SqlMetaType metaType,
        org.hibernate.type.Type hibernateType)

Creates a new instance with specified internal and Hibernate types.

Parameters:

metaType - the internal type

hibernateType - the Hibernate type

SqlType

SqlType(java.lang.String sHibernateType)

Creates a new instance with specified Hibernate type.

Parameters:

sHibernateType - the String representation of the Hibernate type

SqlType

SqlType(java.lang.String sMetaType,
        SqlType previousType)

Creates a new instance with specified internal type.

Parameters:

sMetaType - the String representation of the internal type

previousType - the prevoius value of the input/output value type

Method Detail

getHibernateType

org.hibernate.type.Type getHibernateType()

Returns the Hibernate type.

Returns:

the Hibernate type

getHibernateType

org.hibernate.type.Type getHibernateType(java.lang.Class<?> pojoClass,
                                         java.lang.String attributeName)

Returns the Hibernate type of the attribute in the target pojoClass.

Parameters:

pojoClass - the target class

attributeName - the name of the attribute in the target pojoClass

Returns:

the Hibernate type

getMetaType

SqlMetaType getMetaType()

Returns the internal type.

Returns:

the internal type

setResult

void setResult(java.lang.Object resultInstance,
               java.lang.String attributeName,
               java.lang.Object resultValue)

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

Parameters:

resultInstance - the instance of the result class

attributeName - the name of the attribute in the result class

resultValue - Query execution output value

setParameter

void setParameter(org.hibernate.Query query,
                  java.lang.String paramName,
                  java.lang.Object inputValue)

Bind an input value to a named query parameter.

Parameters:

query - the object-oriented representation of a Hibernate query

paramName - the name of the parameter

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

getValue

public java.lang.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(java.lang.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 java.lang.String toString()

For debug purposes.

Overrides:

toString in class java.lang.Object

Returns:

a String representation for a debug output
