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

---

getEjbQl

public String getEjbQl()

Gets the EJB QL 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

Returns:

true, if the result set is to be local objects

---

getReadAhead

public JDBCReadAheadMetaData getReadAhead()

Gets the read ahead metadata for the query.

Specified by:

getReadAhead in interface JDBCQueryMetaData

Returns:

the read ahead metadata for the query.

---

isLazyResultSetLoading

public boolean isLazyResultSetLoading()

Specified by:

isLazyResultSetLoading in interface JDBCQueryMetaData

---

equals

public boolean equals(Object o)

Compares this JDBCQlQueryMetaData against the specified object. Returns true if the objects are the same. Two JDBCQlQueryMetaData are the same if they are both invoked by the same method.

Parameters:

o - the reference object with which to compare

Returns:

true if this object is the same as the object argument; false otherwise

---

hashCode

public int hashCode()

Returns a hashcode for this JDBCQlQueryMetaData. The hashcode is computed by the method which invokes this query.

Returns:

a hash code value for this object

---

toString

public String toString()

Returns a string describing this JDBCQlQueryMetaData. The exact details of the representation are unspecified and subject to change, but the following may be regarded as typical:

"[JDBCQlQueryMetaData: method=public org.foo.User findByName(java.lang.String)]"

Returns:

a string representation of the object
