Method Detail

getMethod

public Method getMethod()

Description copied from interface: JDBCQueryMetaData

Gets the method which invokes this query.

Specified by:

getMethod in interface JDBCQueryMetaData

Returns:

the Method object which invokes this query

---

getQLCompilerClass

public Class getQLCompilerClass()

Specified by:

getQLCompilerClass in interface JDBCQueryMetaData

Returns:

EJBQL compiler implementation

---

getJBossQL

public String getJBossQL()

Gets the JBossQL query which will be invoked.

Returns:

the ejb ql String for this query

---

isResultTypeMappingLocal

public boolean isResultTypeMappingLocal()

Description copied from interface: JDBCQueryMetaData

Is the result set of ejbSelect is mapped to local ejb objects or remote ejb objects.

Specified by:

isResultTypeMappingLocal in interface JDBCQueryMetaData
